Why Iris Recognition Is The Highest Accuracy Biometric Technology?

The iris is formed by complex fibrous tissue, it contains many similar spots intertwined filaments , coronal, which is fixed in a random combination before birth, and wont be changed during full life. Iris Recognition have the highest accuracy in all biometrics identification.

1. The biological activity

The iris is the visible part of the human eye, under protection of sclera , with strong biological activity. For example, the size of the pupil will changed with light intensity and environment changes; When human brain have been dead, deep coma or the eye are out of body, the iris organization will be fully contracted, appears mydriasis . The biological activity exist together with human life,symbiosis together, so it is impossible to cheat via using photographs, videos, corpses iris.

2. The non-contact 

Grasping iris image distance from users, without user touching the device，did not infringe on the personal privacy, which be accepted widely by the public.

3. Uniqueness

Iris fibrous tissue is very complex ,even if cloning technology can not replicate an iris.

Twins' iris texture information are different, same person's left and right eye iris is also different.

4. Stability 

The iris is extremely stable in one's life, it has been formed before birth (fetus at 7 months) and stereotypes in 6-18 months after birth , then keep same status for whole life.And it wont be injured by general disease , and wont be wear and tear by occupational factors.

5. Security

It is impossible to change a person's iris characteristics to another particular object.

Therefore, if the Iris System is widely used in access control systems, will greatly enhance the safety and reliability of the door access control system operation, reducing possibility of illegal and criminal activities. Iris Recognition Access Control System will be more and more popular all over the world.

Dual Eyes Iris Recognition System’s Basic Constituent Elements

The iris is the annular tissue between pupil and sclera , it is the visible part of the human eye. As one of biometric identification, iris recognition have same functions as other biometrics , which having a user identity identification authenticity features.

In the information system, password authentication is basic identification method which be used frequently.  With the development of information security attack and defense technology, password authentication cannot satisfy our security requirements, because of its low security intensity, and problems from using and remembering. Then fingerprint, Iris Recognition Access Control System and other biometric technologies are more and more favored.

Iris System includes the following modules: the iris image acquisition, iris image processing, user registration, user identification processing, data storage traffic management. These modules are used to achieve two basic functions: user registration and user identification.

For user enrollment, the image acquisition module scan employee iris image, processing features data, and save these information together with user information into the database; For user identification, user identification information is generated,and be compared with information in database , show a comparison result.

Iris recognition system consists of software and hardware.  

Software is for iris information processing, user registration, user identification, iris image storage and management, iris characteristics storage and management; 

Hardware including Dual Eyes Iris Scanner, Iris Access Control, Iris time attendance etc.,which for iris scanning and data saving.

Face Recognition Algorithms and Application

1. The face recognition technology details

Generally, the facial recognition system includes image collection, face location, image preprocessing and recognition . System get features of face, and code them into data on basis of facial recognition algorithm, then compare coded data with system database for verifying. 

The current face recognition algorithms can be classified as follows:
(1) MMP-PCA recognition algorithms
(2) Feature-based recognition algorithms
(3) Appearance-based recognition algorithms
(4) Template-based recognition algorithms
(5) Recognition algorithms using neural network

2. The face recognition application
(1) Criminal Investigation detection
   Detecting target information from the database of the facial recognition system. 
   For example, install this system in airport or station to arrest the fugitives.
(2) Biometric Attendance
   Comparing employee features with face templates in database of Facial scanning clocking systems, and record the attendance information, then calculate report at end of month. 
(2) Access Controls
   Identify the identity by user face, who want to entered the secured area.
(3) Camera Surveillance System
   Monitor the crowd in public places, in order to achieve the purpose of identification. 
   Such as monitoring systems at airports to prevent terrorists from boarding.
(4) Network Applications
   Face recognition plays an auxiliary role for credit card online payment, in order to 
   prevent non-credit card owners use credit cards.

Advantages of Face Recognition Technology

In daily life, we do recognize each other not by fingerprints, palm prints, iris, etc., but by human face . Thus,  facial recognition technology is the most attractive one among biometric technology , it is the most intuitive and natural , it has the following advantages:

                             

1. Non-contact, user acceptance is high 
Facial recognition technology using cameras as the identification information acquisition, itobtain human facial features and complete face verifying in non-contact automatically.

2. High speed identification
Compared with other biometrics authentication technology, face recognition is a kind of automatic identification technology, which with faster verification. Not perceived characteristics comparing is important, which makes the identification method is not offensive, and because it is not easy to cause people's attention.

3. Difficult to counterfeit 
Face recognition technology requires identification object must come to scene for verifying, do not accept fakers. On basis of this unique ability, it wont be deceived by others inactive photographs, puppets, or wax head.

4. Wide application fields In addition to all current applications of fingerprint recognition, such as Time and Attendance, Access Control System . Face recognition also can be applied to all kinds of people face video surveillance alarm system,digital camera, and the future of robots, it has a broad market prospect.

Development Trends of Facial Recognition

1. Combined with video surveillance,CCTV 
With the further development of facial recognition technology, the face recognition systemtechnology will be enable integrated with the CCTV digital monitoring system, which become another major application field of face identification . 
According to statistics, only in China, is expected to form over 10 billions market in following three years, and more than hundreds of billions market in following 10 years in future.

2. Gradually replace the fingerprint attendance Face Recognition Attendance System, through verifying some of the unique face features for employee time tracking. With the help of infrared technology, facial time attendance access control has exceeded diurnal light, can achieve rapid identification in the natural state. Currently, the face recognition attendance products on the market is still in an initial development of the state, but the advantage of face recognition time attendance technology ismore and more obvious than other similar products.

Face Recognition Attendance completely Eliminate buddy punching, eliminating the embarrassment of fingerprint attendance use in contact.
On basis of Non-contact, intuitive, friendly and very broad applicability, with the technology continues to mature and to reduce costs, gradually revealing trends that the fingerprinttime attendance will be substituted by face attendance.
