Four characteristics of AI security in 2021

In recent years, artificial intelligence technology has begun to be applied on a large scale in the security market, vigorously promoting the innovation and evolution of the traditional security industry, and security has also become the most basic and fastest-growing application landing industry of artificial intelligence technology. At this stage, machine learning, deep learning, self-identified language processing, robotics, computer vision, etc. are the most important development areas of artificial intelligence technology. The development of these sub-fields cannot be separated from the massive data sets in the security field for algorithm training. At present, artificial intelligence technology has formed large-scale landing applications in several scenarios such as smart policing, smart transportation, smart communities, smart construction sites, scientific and technological epidemic prevention, and emergency management.

At this stage, security has two major characteristics. One is that in the traditional video-based security industry, after years of development, a large amount of data resources have been accumulated to meet the requirements of artificial intelligence based on big data-based algorithm model training; The characteristics of pre-prevention, response during the event, and tracing after the event in the security industry also coincide with the fit of artificial intelligence algorithms and technical applications. Therefore, artificial intelligence technology will inevitably bring huge changes and influences to the security industry, and promote the rapid development and progress of the industry.


Broaden the boundaries, video surveillance will become a strategic infrastructure

With the integration of new technologies such as artificial intelligence and the Internet of Things, the security industry presents new business models, and the boundaries are constantly being widened. The largest sector is still the video surveillance field. According to data, video surveillance systems account for 54% of the security market and are the most important segment of the security industry. For example, the application of AI+AR technology, through camera video tag addition, video intelligent analysis, realization of video real-world map, visual inspection and other functions, the camera is no longer just a means to achieve security, but also the most important way to obtain images and videos in the Internet of Things era. Information portals and carriers will become the strategic infrastructure of an information society.

Increasing demand for analysis capabilities in China and Taiwan

Compared with traditional security, the AI algorithm middle station can eliminate the interference factors in the surveillance scene and complete the main target path and related functional analysis. The analysis center also puts forward new requirements for the integration capabilities of security companies, not only to improve the efficiency of compatibility between the algorithm side and the front end, but also to avoid the simple application of structured data, and to truly realize the benefit of customers through analysis capabilities The goal of achieving high-quality big data structure and achieving excellent and precise decision-making. In general, the demand for high-end intelligent security equipment with analytical capabilities will continue to grow.

Edge computing and central intelligence combined application

With the continuous extension of security intelligence, the industry’s demand for AI algorithms is increasing, and most smart city solutions require corresponding algorithms to implement related functions. Taking smart transportation as an example, the current bayonet capture requires tracking of vehicle license plates, models, and trajectories, and processing these data requires lightweight data fusion. With the improvement of the hardware performance of smart cameras, more calculations are transferred to the edge, and preliminary analysis and processing of data are completed at the front end, realizing the liberation of the back-end computing power.

Edge computing and smart centers are indeed an indispensable part of the construction of smart cities. IDC data shows that the global edge computing market will reach 41.1 billion U.S. dollars in 2020, which is equivalent to half the output value of the security market. As the smart era continues to deepen, Edge computing is bound to bring greater technical and commercial value, which is also a rare opportunity for the development of security companies.

The 3D reality is gradually mature, and the market has great potential for development

Most of the existing security system solutions are deployed on two-dimensional maps (GIS). With the maturity of three-dimensional technologies such as BIM, CIM, and oblique photography, most of the security monitoring systems in the past two years have achieved three-dimensional real-world upgrades. , Because it is a new thing, the current applications are not rich enough and have great development potential. The reconstruction algorithm integrated with artificial intelligence can bring a full-chain optimization and upgrade to the 3D modeling industry, and realize intelligent data preprocessing, intelligent reconstruction and intelligent data application. Breaking the traditional three-dimensional model, understanding and giving the model real scene information, the semantic three-dimensional model that can be perceived, recognized and used by the machine is the necessary foundation for the intelligent future.

Access Control Models: How to Navigate Changing Security Frontiers

Access control helps organizations ensure security both online and offline. Here’s how to do it.

As businesses undertake digital transformation projects frontiers expand in both physical and digital spaces, access control has become about more than just keycards and security kiosks. The need for more robust security across organizations has led IT leaders to explore various access control systems, including examining how different access control models and management structures could work together to benefit business. 

But before an access control management structure or model can be implemented, let’s take a look at access control in the interconnected age.  

What Is Access Control and How Does It Work with IoT?

Access control is a security technique that regulates who or what can view or use resources in any environment. There are two main types: physical and logical. Both forms of access control are concerned with entry to restricted areas but vary on how to define those areas.  

Logical access control addresses who or what can attain virtual access to data, digital resources and computer networks (think password-protected documents or two-factor authentication). Meanwhile, physical access control impedes bodily access to buildings, rooms or other tangible assets (think metered gates or doors that lock automatically). 

The rise of the Internet of Things has transformed access control. Security cameras, card readers, locks and more can now connect via a single wireless network, allowing security managers to control them from various software-based platforms. Whether it’s using a smartphone to open a door or monitoring security footage via a tablet from a remote location, IoT has increased the mobility and scope of access control in a way never before seen on previous systems.  

But even as the IoT revolution changes access control, it can create added vulnerability for hackers looking to exploit these interconnected networks. That’s where access control models and management become key.

Understanding Access Control Models and Management

There are three primary models of access control:

Web-based access control systems are entirely cloud-based and store permissions on the web rather than on a physical device. This model allows security managers greater access and visibility into the areas they’re monitoring and makes it easier to update or change security permissions in real time from any location. 

Mobile-based access control models function in much the same way. Using a smartphone, security teams can remotely access every aspect of a business’s security system — from the password-protected server to a locked door — to update and change permissions via codes sent over Wi-Fi or cellular signal.

For businesses looking for even greater mobility, connecting all access control software and hardware via one network allows security managers to update these devices all at once in real time. This IoT-based access control model keeps systems up to date with the latest security patches.

However, these models can create their own security risks. Anything cloud- or web-based, or which links several devices to one source, can easily fall prey to hackers. Access control management systems can reduce this increased cybersecurity risk by clearly identifying who can access secured information. 

What Are the Types of Access Control?

Mandatory Access Control (MAC) management is the strictest management option and cedes total control of an entire operating system — doors, cloud-based services, elevators, smartphones — to a system administrator. Without this administrator’s permission, no one and nothing can gain access. 

Discretionary Access Control (DAC) management is one step down from MAC and allows businesses to decide who has access to which areas. Think of this as a bit like the official guest list for a party: The people on the list have access to the party, but they can’t bring a friend and might not have access to every room at the event. Unlike with MAC systems, there is no single entity that grants permissions. 

Similar to DAC, Role-Based Access Control (RAC) grants permissions based on certain criteria. Here, a user might have access to his or her personal email, but not to a business’s private files on the same server. This allows businesses to create layers of security and grant access based on unique needs. 

Last, Rule-Based Access Control (RBAC) is a mixture of DAC and RAC. Here, an individual or list of individuals have access to certain areas based on unique needs but must abide by certain rules (think of elevators that lock out employees after hours, regardless of whether they have keycards). 


How to Choose an Access Control Model and Management System

No one type of access control is foolproof, and no one model or management structure is better than another. What’s important is that a business identifies its end goal before implementing any type of access control structure. 

R&S Erection of Concord, a California-based vendor of garage doors, commercial gates and loading dock equipment, recommends following four steps when selecting access control:

  1. Consider access control policies, models and mechanisms. As outlined above, the model and management structure selected is critical to the success of access control. Choosing the model and structure helps identify the hardware and software requirements.
  2. Know the hardware and security requirements. Hardware will vary based on what level of security is needed and what kind of authentication process is required. For instance, fingerprinting will require different hardware and offer a different level of security than, say, keycard readers or facial recognition requirements.
  3. Assess connectivity and costs. Not all access control systems work with all types of operating systems. Some offer web-based connectivity solutions that may require network upgrades. Consider network capacity and the cost of additions or extensions before selecting certain access control models.
  4. Plan for the future. While many access control system vendors will offer upgrades, make sure to examine such policies before purchasing. Also consider future business developments before committing to one type of access control model or management structure.  


What is facial recognition?

Facial recognition is a way of identifying or confirming an individual’s identity using their face. Facial recognition systems can be used to identify people in photos, videos, or in real-time.

Facial recognition is a category of biometric security. Other forms of biometric software include voice recognition, fingerprint recognition, and eye retina or iris recognition. The technology is mostly used for security and law enforcement, though there is increasing interest in other areas of use.

How does facial recognition work?

Many people are familiar with face recognition technology through the FaceID used to unlock iPhones (however, this is only one application of face recognition). Typically, facial recognition does not rely on a massive database of photos to determine an individual’s identity — it simply identifies and recognizes one person as the sole owner of the device, while limiting access to others.

Beyond unlocking phones, facial recognition works by matching the faces of people walking past special cameras, to images of people on a watch list. The watch lists can contain pictures of anyone, including people who are not suspected of any wrongdoing, and the images can come from anywhere — even from our social media accounts. Facial technology systems can vary, but in general, they tend to operate as follows:

Step 1: Face detection

LThe camera detects and locates the image of a face, either alone or in a crowd. The image may show the person looking straight ahead or in profile.


Step 2: Face analysis

Next, an image of the face is captured and analyzed. Most facial recognition technology relies on 2D rather than 3D images because it can more conveniently match a 2D image with public photos or those in a database. The software reads the geometry of your face. Key factors include the distance between your eyes, the depth of your eye sockets, the distance from forehead to chin, the shape of your cheekbones, and the contour of the lips, ears, and chin. The aim is to identify the facial landmarks that are key to distinguishing your face.

Step 3: Converting the image to data

The face capture process transforms analog information (a face) into a set of digital information (data) based on the person’s facial features. Your face’s analysis is essentially turned into a mathematical formula. The numerical code is called a faceprint. In the same way that thumbprints are unique, each person has their own faceprint.

Step 4: Finding a match

Your faceprint is then compared against a database of other known faces. For example, the FBI has access to up to 650 million photos, drawn from various state databases. On Facebook, any photo tagged with a person’s name becomes a part of Facebook's database, which may also be used for facial recognition. If your faceprint matches an image in a facial recognition database, then a determination is made.

Of all the biometric measurements, facial recognition is considered the most natural. Intuitively, this makes sense, since we typically recognize ourselves and others by looking at faces, rather than thumbprints and irises. It is estimated that over half of the world's population is touched by facial recognition technology regularly.

How facial recognition works

How facial recognition works
You might be good at recognizing faces. You probably find it a cinch to identify the face of a family member, friend, or acquaintance. You’re familiar with their facial features — their eyes, nose, mouth — and how they come together.

That’s how a facial recognition system works, but on a grand, algorithmic scale. Where you see a face, recognition technology sees data. That data can be stored and accessed. For instance, half of all American adults have their images stored in one or more facial-recognition databases that law enforcement agencies can search, according to a Georgetown University study.

So how does facial recognition work? Technologies vary, but here are the basic steps:

Step 1. A picture of your face is captured from a photo or video. Your face might appear alone or in a crowd. Your image may show you looking straight ahead or nearly in profile.

Step 2. Facial recognition software reads the geometry of your face. Key factors include the distance between your eyes and the distance from forehead to chin. The software identifies facial landmarks — one system identifies 68 of them — that are key to distinguishing your face. The result: your facial signature.

Step 3. Your facial signature — a mathematical formula — is compared to a database of known faces.

Step 4. A determination is made. Your faceprint may match that of an image in a facial recognition system database.

In general, that’s how facial recognition works, but who uses it?

Facial recognition system

facial recognition system is a technology capable of matching a human face from a digital image or a video frame against a database of faces. Researchers are currently developing multiple methods in which facial recognition systems work. The most advanced face recognition method, which is also employed to authenticateusers through ID verification services, works by pinpointing and measuring facial features from a given image.

While initially a form of computer application, facial recognition systems have seen wider uses in recent times on smartphones and in other forms of technology, such as robotics. Because computerized facial recognition involves the measurement of a human’s physiological characteristics facial recognition systems are categorised as biometrics. Although the accuracy of facial recognition systems as a biometric technology is lower than iris recognition and fingerprint recognition, it is widely adopted due to its contactless and non-invasive process. Facial recognition systems have been deployed in advanced human-computer interactionvideo surveillance and automatic indexing of images. Techniques for face recognition While humans can recognize faces without much effort, facial recognition is a challenging pattern recognition problem in computing. Facial recognition systems attempt to identify a human face, which is three-dimensional and changes in appearance with lighting and facial expression, based on its two-dimensional image. To accomplish this computational task, facial recognition systems perform four steps. First face detection is used to segment the face from the image background. In the second step the segmented face image is aligned to account for face pose, image size and photographic properties, such as illumination and grayscale. The purpose of the alignment process is to enable the accurate localization of facial features in the third step, the facial feature extraction. Features such as eyes, nose and mouth are pinpointed and measured in the image to represent the face. The so established feature vector of the face is then, in the fourth step, matched against a database of faces.

Access control system connection mode and several networking modes

With the deepening of the degree of electronic intelligence in society, the access control systems we see now can be divided into: password access control systems, swipe card access control systems, and biometric access control systems based on different input devices, media and methods.

1. Integrated access control, also called independent access control

We started from the most primitive. This is also the most used office in some office buildings and the most affordable and cheap one. It is an access control machine, electromagnetic lock, door opening button, and power supply, which are combined to form a whole. It is installed on the gate to realize the access management function. If you need a larger function, you need to add a set of software. The premise is to realize the digitalization, which means that it needs to be connected to the Internet and establish an independent intranet. The following picture shows the integrated access control network diagram

     Advantages: The integrated access control is the first-level product of access control. It is simple and convenient to network, install, and debug. It is an essential system for small offices. The integrated access control has the following functions: password to open the door, swipe card to open the door, and button to open the door.

Disadvantages: Cannot realize network remote management, access control cards can only be authorized locally, and remote access control cards cannot be authorized. The total amount of access control cards is limited, and most of them can only store 2000 access control card information

  • RS485 access control mode

 Through the RS485 communication bus (must use a twisted pair or a set of network cables), the controller is connected to the RS485 converter (hub) by hand in series, and then connected to the computer serial port to achieve One computer (software) manages and communicates with multiple controllers.                                                   

 The theoretical distance between the farthest controller and the computer is 1200 meters. It is recommended that the customer control it within 800 meters, and the best results can be controlled within 300 meters. If the distance is too long, you can purchase a 485 repeater (extender) (please buy from a professional converter manufacturer. Whether the repeater is placed in the middle of the bus or the beginning, please refer to the instructions of the relevant manufacturer.) The repeater can theoretically be extended to 3000 meters

  • TCP/IP communication mode

The TCP/IP communication protocol is the current universal standard protocol for computer networks. It has the advantages of fast transmission speed, international standards, and good compatibility.

 The access method of the controller is the same as that of the HUB and computer network card of the local area network.

Communication distance:

 In a small local area network, the communication distance can be extended through the cascading of HUB, the communication distance of each level is up to 100 meters, and multiple levels can be cascaded. Moreover, large-scale local area networks can be extended to a long distance or even many kilometers through various methods such as optical fiber and wireless, and even across cities, it can also be connected to thousands of kilometers through the Internet. Number of loads: There is no limit in theory, HUB can be cascaded, and thousands of controllers can be networked without problems.

Communication speed:

The communication speed is fast. The communication speed of TCP/IP products is ten times or even dozens of times that of RS485 RS232 controllers. Up to 100 or even hundreds of upload permissions or download records per second. The following figure shows the networking mode of the network access control system

In summary, now is the era of the Internet. 485 bus-controlled access control has been withdrawn from the stage of history. The network access control system is the mainstream of the society. The additional functions of the network access control are more complete, making life more intelligent and faster. Therefore, weak current equipment is constantly being updated, moving towards more intelligent equipment and realizing the Internet of Everything

Security integration

Driven by the advancement of science and technology and people’s demand for mobile communication services, building access control intercom systems are being applied to communities. So how does the high-intelligence access control realize the integration of security and protection? What aspects of the integration of security and protection should be paid attention to? Is it necessary to focus on customer needs? Finally, what are the prospective advantages of placement integration in smart access control? Here are the answers for readers one by one.

Alarm and event information management

The integrated security system based on the access control system mainly includes two parts: a front-end controller and a management platform. This way of integration based on the access control system is that the main functions served by the overall system are biased towards access control and entrance and exit management. “When an event occurs, the alarm front-end system must first detect the target. After the alarm information is transmitted back to the management center, it can be viewed in real time by calling the video image. However, in this series of reactions, the alarm system is only An early warning mechanism, while the video system realizes review and review, only the access control system can truly control the on-site conditions.

Of course, once an event occurs, all alarm events of the system (access control, alarm, patrol, etc.) can be linked to the hard disk recording system of the TV monitoring system and the matrix controller to respond accordingly. For example, when a door in the access control system is opened illegally, the integrated system will control the matrix controller of the TV monitoring system to switch the camera image corresponding to this door to the main screen of the TV monitoring system display screen and the management platform of the integrated system, and go Start the hard disk video recorder to record. If the camera has a PTZ, you can also control the PTZ to rotate to the preset position on the management platform.

At the same time, the system also has the function of triggering the execution of script programs by alarm events, which can associate some alarm events with DVR control according to user needs, for example, when an alarm event starts, trigger DVR to start recording and perform remote control of DVR Program, you can also query and retrieve video information as required.

In addition, you can view the live video at the time through the alarm event record of the access control system. The matrix control module of the system can also directly control the selected camera, and the control protocol of the matrix controller such as PELCO, PHILIPS, PANASONIC, etc. is usually built-in to realize the Control of other brands’ matrix.

Integration with other software

For security system integration, it is not only the integration between the hardware, but also the integration with other software (such as: fire alarm, building automation, information release, elevator control, consumer system, daily management, etc.). Integration depends on the degree of protocol openness of various hardware devices, that is, whether these hardware devices provide interfaces and protocols.

Only when the hardware provides a unified interface (SDK or API function), the software can manage and control the hardware uniformly through the interface, and grasp the working status of the hardware from time to time. Of course, the software should also provide linkage strategies and pre-plan mechanisms. At the same time, the software integration of the system should also support hierarchical management. For example, the software integration in the rail transit system includes the software integration of the operation management center and the station-level software integration.

However, different hardware provides different interfaces, which requires us to modularize the software, and we use a module for each hardware to manage it. Because of different projects, the front-end equipment used is not exactly the same. It is impossible to take a project, it is necessary to develop or purchase a set of software. Just like WINDOWS is an operating system platform software, you can install and use it no matter what hardware configuration your PC has, because different hardware has corresponding drivers for WINDOWS. Change an accessory, just reinstall the corresponding driver. Therefore, security integrated software will also gradually realize ‘platform’ and ‘module’.

The interface provided by the hardware should be able to provide functions such as status access, device operation, system configuration, etc., through the TCP/IP protocol, the unified management of various hardware and the realization of hardware functions to achieve system integration. However, in the current Chinese security market, many manufacturers are unwilling to disclose their product agreements in order to ensure their market share. Therefore, the compatibility between brand products is poor and the integration level is relatively low.

Understand end user needs

In addition to understanding the key technologies of integration, integrators and engineers also need to truly understand the actual needs of end users. At present, many end users blindly pursue multiple and complete integration functions, but lack understanding of system integration, which often results in waste of system functions. For example, many building developers pay too much attention to the appearance and price of the system, and often only pay attention to the partial effect, and do not consider whether the entire system is reasonable. It can be said that technology is often ignored for economic benefits. In addition, some developers think that having a brand is a good project, and some users simply do not combine their actual needs, blindly pursuing the powerful and complex functions of the system, thinking that the bigger the system, the better. In fact, such integrated systems are often put aside because they are either impractical, unusable, or too complex in function.

Therefore, for end users, when making system planning, they should first understand their actual needs and the effect of system integration. For example, which subsystems need to be integrated in the engineering project? If it is an access control system, what degree of integration must be achieved, how to link with other systems (alarm system, access control system), etc., all of which need to be contacted by the engineering company or Integrators communicate to avoid deviations between their own needs and the integrated results.

In addition, according to industry insiders, the current demand in China’s security integration market is experiencing a period of restlessness. Since many system integrators are transformed from engineering companies or network operators, the technical level of each integrator is also uneven. Most of the system integration construction parties do not have their own technical strength, and the overall planning and potential of the system The function mining is not enough to optimize the system, which is only limited to installation and debugging; some integrators fully cater to some unreasonable needs of customers in order to expand their business, making “system integration” seriously distorted or misunderstood.

Therefore, whether it is a security manufacturer, a system integrator, or an engineering company involved in a system integration project, it is necessary to continuously strengthen its own understanding and understanding of system integration and improve the level of integration technology in order to select a more suitable platform for customers to achieve The effect the customer expects to achieve.

What is an access control system?

What is an access control system? The concept of the original access control system has been in our lives. For example, we have installed doors and locks in every household. When the family members go home, they can use the key to open the door and enter. However, when outsiders come, people in the house need to hear the sound of knocking on the door. Judge whether to open the door by sound and past experience.

Access control system, also known as access management control system and channel management system, is a new modern intelligent management system. It is an effective measure to solve the security management of the entrances and exits of important departments. Applicable to various scenarios, such as banks, hotels, parking lot management, computer rooms, prisons, express cabinets, office rooms, intelligent communities, factories, etc.

With the deepening of the electronic intelligence of society, the access control systems we see now can be divided into: password access control systems, card access control systems, biometric access control systems, mobile APP access control systems based on different input device media and methods.

Password access control system: By entering the password, the system judges that the password is correct and the door is opened. Advantages: Just remember the password. Simple. Disadvantages: slow speed and poor security. Trend: There are fewer and fewer occasions for password access control. It is used in occasions with low safety requirements, low cost and infrequent use. For example: safe.

Card access control system: According to the type of card, it is divided into contact card access control system (magnetic stripe card, barcode card, chip card) and non-contact card (also called proximity card radio frequency card) access control system. The contact card access control system is mainly used in bank card related In occasions, non-contact IC cards are widely used due to their high durability, good cost performance, and fast reading speed. The disadvantage is that they are easy to be copied. (Note: Ordinary IC/ID cards are easy to be copied, CPU cards are also called encryption cards, which are not easy to be copied, but the cost is higher)

Biometric access control system: An access control system that recognizes identities according to different human biological characteristics. Mainly include: fingerprint access control system, palm profile access control system, iris access control system, face recognition access control system. Advantages: no need to carry media such as cards, less chance of repetition, not easy to be copied, high security, disadvantages: high cost. The comparison speed is slow, which is not conducive to occasions with too many people. The biological characteristics of the human body will change with the environment and time, and the recognition rate is low. Although the biometric access control system is advanced and safe, the scope of application is limited.
