Application of biometric identification technology in access control system

 
With the continuous development of biometric identification technology and the continuous maturity of technical application, its application in the access control system is also increasing. Biometric identification technology is more secure, confidential and convenient than the traditional identification method. With the advantages of not easy to forget, good anti-counterfeiting performance, not easy to forge or stolen, portable and available anywhere, etc., access control products combined with biotechnology, thus appearing fingerprint access control machine, finger vein access control machine, iris access control machine, a variety of biological card reader and other biometric access control products. Biometric products in line with the market demand for access control, in line with the security product development strategy, can enhance the competitiveness of the overall security solutions, is one of the essential products for industry applications, to enhance the overall project design highlights, security level. Now, biometric products are gradually turning to the civilian market, into the public security construction.
 
Biometric products can be applied to different occasions, according to different occasions can choose different technologies of biological access control products, high security premises can choose finger vein, iris products, small office premises can choose fingerprints and other access control products.
 
Biometric access control products have high security, after all, biometric features can not be forged, and the only characteristics, so in today's relatively strict environment for information security, choose the most advanced biometric products, such as iris, vein, etc., can fully meet the customer's high security requirements for the system, and can use inductive card technology, and combined with multiple identification technology, can more enhance the security level of the product.

Comparison and application of various biometric technologies

 
Biometric technology samples human biometric features, extracts the features and converts them into digital codes, and further forms these codes into feature templates. Nowadays, biometric features that can be used for biometric identification include hand shape, fingerprint, face shape, iris, retina, pulse, ear, etc., and behavioral features include signature, voice, keystroke strength, etc. Based on these features, people have developed various biometric technologies such as hand shape recognition, fingerprint recognition, face recognition, pronunciation recognition, iris recognition, signature recognition, etc.
 

Fingerprint recognition

 
Fingerprint recognition means identification by comparing the detailed feature points of different fingerprints. Since each person's fingerprints are different, even between the ten fingers of the same person, fingerprints have obvious differences, so fingerprints can be used for identity identification.
 
The advantage of fingerprint identification technology applied in the second generation ID card is that the application is relatively convenient, long application time and high recognition, but fingerprint is a feature that can be easily stolen and copied, and its security is low compared to other biological features. In addition, the stability of fingerprint characteristics is poor, peeling, epidermal callus, dry and wet state will affect the application of fingerprints. Second generation ID card collection process like farmers, workers and other groups will appear a large number of problems can not be collected, because fingerprints everywhere can leave traces, more favorable to public security criminal investigation, but because of easy to copy, but also for the anti-criminal investigation brought convenience.

Face recognition

 
Face recognition technology is a biometric identification technology based on the information of human face features for identity recognition. A camera is used to collect images or video streams containing human faces, and automatically detect and track faces in the images, and then perform a series of face-related technologies on the detected faces, including face image acquisition, face positioning, face recognition pre-processing, memory storage and comparison identification, to achieve the purpose of identifying different people's identities. Face recognition technology is is a convenient collection of features, but because the face is three-dimensional, subject to light, expression, fat, thin, hair, movement greatly affected, but also because it is also surface features, easy to be forged copy, used to do identification, criminal investigation when stability and security is low, if the technology has a breakthrough, in public security and other fields will be widely used.

Iris Recognition

 
Iris technology is an identification technology that uses the textural characteristics of the iris of the human eye, and iris recognition is more accurate. The iris is a fabric-like ring of various colors within the pupil of the human eye, and each iris contains a unique structure based on features like crystals, filaments, spots, structures, dimples, rays, wrinkles and stripes, and it is claimed that no two irises are the same. Iris recognition is one of the more accurate ones in terms of technical specifications, but in terms of use it requires irradiation of the eyes by infrared light or visible light to obtain an image, with a low degree of user cooperation and a high degree of psychological rejection, and therefore is not applicable to large crowd applications like ID cards. In addition, products such as contacts that appear on the market today can change the characteristics of the iris and are relatively easy to replicate. Iris recognition technology, at present, has been realized in China's coal mine workers attendance, prison inmate management, bank vault access control, border security clearance, military security system, candidate identity verification and other fields.
 

Finger Vein Recognition

 
Finger vein recognition technology is a new biometric identification technology, which uses the image of vein distribution in the finger to carry out identification. Medical research has found that when a finger is irradiated with near infrared light, the hemoglobin flowing in the vein absorbs the near infrared light thus forming an image of the blood vessels, and the sensor can acquire the image of the finger vein and form a specific finger vein feature template through algorithmic processing. It is medically verified that each person's finger vein image is different and the formed template is a unique biometric feature that can be used for identification purposes.
 
Finger vein identification technology is different from other biometric technologies such as fingerprint, iris, face, etc. because its biometric feature carrier vein is located inside the finger, unless a living finger is copied, the image of blood vessels formed by flowing blood is difficult to obtain and be copied through ordinary technical means, which is non-epidermal feature, safe, efficient and convenient. Among many biometric technologies today, finger vein technology is the one with the highest security level and technical index, and its usage habit is similar to that of fingerprints. Its wide application and supplementing or replacing fingerprint technology in most fields will be the trend of future identification.
 

Competition of biometric identification

 
As seen from the above, the competition among these biometric technologies is mainly reflected in: first, the maturity degree of the technology itself; second, the convenience of use; third, the promotion ability of biometric product manufacturers; fourth, the market application response, such as fingerprint and face recognition, which were commonly adopted by judicial institutions in the early days. It can be foreseen that these technologies will co-exist for a long time and integrate their use. Long-term coexistence, because they even if the market overlap, still will not completely replace, and the market application can be constantly subdivided, different technologies can find their own development space, more important trend is that the current diversified market, such as the combination of fingerprint and face, the combination of iris and fingerprint, a variety of multiple biological simultaneous application, organic combination it can greatly enhance the reliability, accuracy and strict judgment of the system. It can build on the strengths and avoid the weaknesses and further bring into play the advantages of biometric identification.
 

The shortcomings of biometric identification products

 
From the aforementioned comparison of various biometric identification technologies, it can be seen that the technology of fingerprint is already open and can be cracked completely, in addition, most of the current fingerprint module manufacturers choose the optical fingerprint identification mode, because the price of this module is relatively low, it is easier to reduce the cost of fingerprint products, but the optical module is easily affected by external factors and cannot be installed directly outdoors, such as by direct sunlight will affect the normal work of the module. The module's normal work, and the electrolytic fingerprint module is slightly higher in cost, which increases the product cost. Coupled with the fact that fingerprint identification technology is already transparent and completely replicable, fingerprint products will gradually be replaced in the selection of industry application products.

To continue to develop fingerprint technology, we must first solve the problem of fingerprint being copied. Strengthening the live fingerprint identification technology and reducing the possibility of being copied is the key to the continued development of fingerprint identification technology.
 
Although facial recognition is also a relatively new application, but there are also shortcomings, this technology because the brightness and angle and facial expressions are different, making facial recognition becomes very complex. And the device is very sensitive to direct light, especially daylight, resulting in a large floating error rejection rate and poor practical application. Only when the technical difficulties of this project are solved, can this technology be widely used.
 
Iris, finger vein and palm vein are by far one of the most advanced biotechnologies and are all unique, so the possibility of being copied is minimal.
 
First of all, iris recognition may have a small chance of being used in large quantities in the civil market because of the complexity of the equipment, the short scanning distance, the strict operation, and the user's psychological concern about health. The palm vein product is slow because of the wide range of recognition contrast, recognition speed is influenced by the registration and authentication placement, and the volume of the product is large, which is not favored for the pursuit of small and concise customer groups, and the use of promotion will be limited; besides solving the product price factor, at the same time the customer acceptance is also the important direction of the later development of these two technologies.
 
Finger vein products actually combine the advantages of the above two technologies and discard their shortcomings, which will be the favored products for the industry market attention, of course, because of the high price factor, it is difficult to open the widely used situation in the civil market for the time being, but when the finger vein module technology is more mature and the module manufacturers are more, the price of the products will be gradually reduced, then the opportunity of the universal application of finger vein products will be just around the corner. This is entirely dependent on the advantages of finger vein authentication technology.

This technology uses near-infrared light to irradiate the finger vein of a living person to obtain an image of the finger vein, encode it, and authenticate it. Live finger veins, the chance of being copied or stolen is very small, low psychological resistance of the subject, subject to the influence of physiological and environmental factors, the accuracy of a number of important features, making it highly secure and convenient to use far better than fingerprint identification technology, is a rising star in the security market, will be widely used in the industry market, the civilian market.
 
For security product suppliers, can not blindly push biometric products, without regard to customer needs, product characteristics, after all, each biometric product application environment is different, so in addition to meet the basic needs of customers, but also need to combine the individual needs of customers, combined with the characteristics of biological products, to provide a complete solution, that is, to show the characteristics of biometric technology, advantages, but also to meet the needs of customers, in order to better promote biometric products marketed, to be trusted and used by customers.
 

Conclusion

 
Diversified, multiple, high-tech biometric identification technology applied to the access control system, access control system as an important part of the security industry, will give a push to the security construction. The author company as access control products production and sales manufacturers, will expand new markets in the process of biometric access control product development and production, and continue to develop new product systems, integration of large security applications, to promote the rapid development of the security industry.
