Identity authentication is the first security barrier for information systems, and it is also a security protection method that runs through the entire process of the system. Since the security authentication of information systems is performed automatically and quickly in the absence of remote monitoring, sensitive information systems are the targets of information hackers. The traditional identity authentication methods can no longer meet the requirements of identity authentication in the information age, and they urgently need to be reliable. High-level, anti-attack capability, convenient and practical authentication technology and products.
As the name suggests, iris recognition technology is a kind of human biometric identification technology. Just as fingerprint recognition is based on identification of fingerprint texture differences, iris recognition is the identification of human identities through the extraction of iris information from the human eye. Human biometric identification technology represented by iris recognition came into being.
The main features of iris recognition technology
1. Biological activity The iris is a visible part of the human eye, under the protection of the sclera, has a very strong biological activity. For example, the size of the pupil varies with the intensity of the light; there is an involuntary adjustment process depending on the time of the subject; there are unconscious pupil scaling up to ten times per second; when the human brain is dead, in a deep coma, or when the eye tissue is detached from the human body, the iris The tissue is completely contracted and appears dilated. These biological activities and human life exist at the same time, symbiotic and symbiotic, so I would like to replace living iris images with photos, videos, and the body's iris are not possible, thus ensuring the authenticity of the physiological organization.
2. Non-contact:
A digital image of the iris can be obtained from a certain distance, without user contact with the device, without infringement of the human body, and thus easily accepted by the public
3. Uniqueness:
Uniqueness means that the information contained in each iris is not the same, and that the appearance of an iris with the same shape is much less likely than other organizations. The details of the fibrous tissue of the iris are complex and abundant, and its formation is related to the local physicochemical conditions of the tissue during embryogenesis. It is extremely random, and even if clone technology is used, it cannot replicate an iris. Iris twins have different iris texture information, and the iris textures of the same person's left and right eyes do not agree with each other.
4. Stability:
The iris is extremely stable in one's life. It has been formed before birth (at 7 months of fetus) and is established after 6-18 months of birth. It will remain unchanged for the rest of the life. The general disease will not cause damage to the iris tissue and will not cause Occupation and other factors cause wear and tear.
5. Anti-counterfeiting:
It is impossible to use surgery to change the iris features without seriously affecting the vision. It is even more unlikely that one person's iris tissue features will be changed to the same characteristics as a specific object. Instead, photos, videos, and the body's iris will replace the living ones. Iris images can be checked out.
