Iris recognition technology is widely recognized as the twenty-first century with the development of biometric authentication technology is the most promising future applications of security, defense, e-commerce and other fields, are bound to iris recognition technology will focus on. This trend is now beginning to show up in a variety of applications around the world, the market prospects are very bright. Iris technology concepts, exterior view of the human eye consists of the sclera, iris, pupil of three parts. White part of the eye sclera that is outside, about 30% of the total area; eye pupil center section, about 5 percent; the iris is located between the sclera and pupil, contains the most abundant texture information, accounting for 65%. In appearance, made up of many crypt, wrinkles, pigment spots, etc., it is one of the most unique body structure. Iris is formed is determined by genes, human genes determine the shape of the iris, physiology, color and overall appearance. Human development to eight months or so, basically the development of the iris to a sufficient size, entered a relatively stable period. Unless rare abnormal status, physical or mental trauma it may cause large changes in the appearance of the iris, the iris morphology can be maintained for several decades have not changed much. On the other hand, the iris is externally visible, but they belong to the internal organization, located behind the cornea. To change the appearance of the iris, a very delicate surgery, but also risked the danger of visual impairment. Iris is highly unique, stability and characteristics can not be changed, is the material basis of the iris can be used as identification. Sclera by the human eye, the iris, the pupil of three parts, the iris is black eyes annular portion is located between the pupil and the white sclera, about 65% of the total area of ??the fibrous tissue rather complex, with many mutually staggered similar spots, filaments, coronal, stripes, and other details recess features that are random combinatorial manner finalized, once formed life unchanged. Iris recognition technology is the use of human iris lifelong invariance and individual differences in the characteristics to be a high-tech identification, which uses optical instruments, non-contact iris image acquisition by computer image processing technology acquired iris image identification, storage, false consciousness was 120 parts per million. Iris has not found repeated cases in the world. After the iris recognition technology in conjunction with the corresponding algorithm, we can reach very good accuracy, even if the iris information of all mankind are entered into a database, and false rejection of the possibility of recognition is quite small. Applications iris iris recognition technology is now the country's application has been started, last year's sales is estimated at about 1? 0 million yuan, strong development momentum. It is expected that the industrialization of our country iris recognition will usher in a bright spring. The main application areas of domestic iris recognition are:? (1) Access and attendance application which is the largest domestic direction other biometric products, domestic sales of foreign iris recognition products are mainly installed in high-end real estate projects for access control? . (2)? Financial? CAS Institute of Automation, technology companies and Ningbo-know eighty-one Group jointly developed iris recognition-based bank safe / cabinet has been put into the market, China's first ATM iris recognition also successfully developed last year, participated in China International Finance (Banking) Technology & Equipment Exhibition. (3)? Electronic passport and second-generation ID card? 2003, published by international organizations will be asked to join the planned biometric (facial recognition, iris recognition, fingerprint recognition) in a personal passport and personal identity when entering the borders of individual countries confirmation. Sooner or later our country will join the program, due to national security, domestic iris recognition system will have a greater competitive advantage. Our second-generation ID card for the implementation of biometric authentication technique reserved space. (4)? Medical insurance and pension insurance payment? China's social security career is booming, because the iris to maintain life-long, iris recognition technology will be used to confirm the identity of the insured, prevent impersonation. (5)? Public security and justice? If fugitive tracking, application and other aspects of judicial investigators. (6)? E-commerce? China has introduced an electronic signature law, if the introduction of iris recognition in a digital signature scheme, will increase the security of online transactions. (7) information security such as file encryption, combined with cryptography and iris recognition. (8)? Specific industry? Such as workers in the mining industry go down the return of the face and biometric hand extraction are affected, it must use iris recognition. It should also clearly recognize and foreign outstanding iris recognition products compared to domestic systems still have a big gap, especially in terms of iris image acquisition hardware devices. The main problem now iris recognition system in practical application is to obtain good quality iris image with the needs of users, hardware cost is relatively high. Therefore, the future development trend of the iris recognition system is to improve the friendly man-machine interface, reduce the cost of acquisition equipment. From the hardware side, a large depth of field can be designed optical lens group, to introduce an automatic zoom technology and assisted positioning technology to improve the usability of the system; the software side, you can use super resolution technology and image enhancement technology to improve image quality by or voice prompts to alert the user with the way the video capture device. In applications requiring a higher level of security environment, the in vivo detection of an iris image is also an important aspect, to prevent counterfeiters theft iris image of others. In order to regulate the iris image data format, unified hardware providers, software developers and data interfaces between systems integrators and promote data sharing between various computer applications to facilitate the exchange of personnel between research, support iris recognition products evaluation, should be put into force as soon as possible the work of iris recognition standardization. Second, the iris attendance is harmful to the eyes: the iris recognition device using pure optical lens, lens combination used internally, using pinhole imaging and reflection imaging principle, under normal conditions is the use of natural light is reflected from the eye to the lens of the light image, does not exist the eyes and the eyes scan emit any radiation. In very dark or no natural light situations using micro heat Infrared forehead fill light scattering to the eye and then reflected to the camera, so even in very dark conditions, the impact on the human body is only in continuous radiation can cause forehead 42 minutes later 0.01-0.03 ℃ skin temperature rises, the human body and the eyes are no injuries. And we will use lighting in practice, therefore, the thermal infrared system will not be excited.
