Iris recognition is a technique that uses the iris features in the human eye to validate identity. In Hollywood blockbuster, the memory of the cool scene of a secured room or safe by scanning the retina of the eye. In the smart phone industry, a large number of companies have introduced iris recognition, including Samsung and several domestic handset manufacturers. Recently there is news that Apple's iPhone 8 this year will be equipped with iris recognition feature. This makes iris recognition once again become the focus of attention.
Iris recognition technology is a kind of human biometrics. The appearance of the human eye by the sclera, iris, pupil of three parts. The sclera is the white part of the periphery of the eye; the center of the eye is the pupil part; the iris is a circular part between the black pupil and the white sclera, containing many interlaced spots, filaments, crowns, stripes, crypts and other details , Is one of the most unique structures in the human body. The formation of the iris is determined by the genetic gene. The expression of the human body determines the morphology, physiology, color and overall appearance of the iris. 18 months after birth, iris styling unchanged for life, except in rare abnormal conditions, the eye injury may cause changes in the appearance of the iris, the iris morphology of normal people can remain unchanged for decades.
Iris recognition is to identify people by comparing the similarities between iris image features. The process of iris recognition generally includes the following four steps: The first step is to acquire the iris image. Use a special camera equipment to capture the entire human eye, and the captured image is transmitted to the iris recognition system image preprocessing software. The second step, image preprocessing. The obtained iris image is processed to meet the demand of extracting the iris feature. The third step, feature extraction. A specific algorithm is used to extract the iris recognition feature points from the iris image and encode it. The fourth step, feature matching. The extracted feature codes and the iris image feature codes in the database are matched one by one to determine whether they are the same iris, so as to achieve the purpose of identification.
As the highest level of security in the field of biometrics, iris recognition has been widely valued in the market. In the application scenarios that require strong authentication, such as opening a bank account, receiving social security funds, enhancing terminal authentication, mobile payment and other fields, iris recognition is more reliable. For example, the iris payment application solves the pain points of bank risk management, especially for large-payment category A accounts, iris recognition technology to ensure account security. At present, Agricultural Bank of China, Bank of Beijing, Minsheng Bank, etc. have all explored the use of this technology. Iris recognition is also promising in setting up an authentication system to help find trafficked children.
Currently, iris recognition products and technologies are widely used in civilian mobile terminal devices such as iris phones, iris pads, iris mice, iris watches, etc., as well as authentication of national security agencies with high security requirements, anti-terrorism military security , Bank vault access control, iris ATM withdrawals system, biological passport authentication, airport clearance system, public security system, and kindergarten transfer in smart cities, smart home access control, smart cars and so on. Previously a car named Ilyelock iris recognition equipment available, the driver only need to take a look at the equipment installed in the rearview mirror, you can start the vehicle. There are also a variety of smart phones built-in iris recognition technology, users only need to "see", you can confirm the true identity, to unlock the boot, phone file encryption, APP no password login, or even password-free iris payment and other functions.
In the field of iris recognition, China's technological level and product development are in the forefront of the world. Since September 2010, the government of India has initiated the establishment of a biometric identification system that provides each individual with a unique 12-digit identification number by collecting iris information and fingerprint information of all Indians, and can make remote inquiries in a networked database.
