Iris recognition camera module background

What is iris recognition?The
human eye is made up of the sclera, iris, and pupil. The sclera is the white part around the eyeball, accounting for about 30% of the total area, the center of the eye is the pupil part, which accounts for about 5%, and the iris is located between the sclera and the pupil and contains the richest textural information, accounting for about 65%, it is one of the most unique structures in the human body. The iris recognition camera module is also based on this principle.
The prospect of iris recognition camera modules
One of the characteristics of the recognition technology of the iris recognition camera module is that it has high precision and high security indicators. This is determined by the complexity and non-reproducibility of the iris structure. According to experts, there is a 75% chance that information from two different iris will match, and the probability that two different iris will generate the same iris code is 1 in 1,000. This is orders of magnitude to orders of magnitude more accurate than any other biometrics.
The shortcomings of the iris recognition technology of the iris recognition camera module are also very obvious. One is to use a camera for shooting, which is easily affected and disturbed by the surrounding light, and the other is to use non-contact data entry, the camera must be aimed at the eyes, and the user experience is poor.
Whether the iris recognition technology of the iris recognition camera module is popular depends on whether the characteristics of the technology meet the needs of users. Perhaps users with higher requirements for security indicators prefer iris recognition technology, such as banks, airports, etc., while the general public may prefer fingerprint recognition as a convenient way to operate. Of course, biometrics only provides one kind of data entry and identification technology, and whether the market can be hot or not, the core is applications and services!
