With the development of artificial intelligence technology, fingerprint recognition and face recognition technology have been very common. At present, taking advantage of technological innovation, iris recognition technology has been widely used and opened up a broad market.
We often see it in sci-fi works, and may even use it in our daily lives. Iris recognition technology is known as the most accurate and unforged perceptual recognition technology, which adds to its mystery.
We are already very familiar with the barcode QR code recognition technology in the perception technology. In fact, the iris recognition technology is a super version of the barcode QR code recognition technology.
But what it recognizes is not the information contained in the barcode two-dimensional code but the rich information hidden on the human iris, and its excellent characteristics are unmatched by the two-dimensional barcode.
Throughout the history of world development, identification technology has always been an important subject that mankind has devoted to research all year round. How to use the inherent physiological characteristics of the human body, such as human face, fingerprints, iris, veins, retina, and behavior characteristics such as handwriting, voice, and gait for identity authentication, has become the core link of modern information security management.
Iris recognition is considered to be the most potential biometric technology. The algorithm realization process is to turn an image into a series of codes, which generally includes four steps of iris image acquisition, image preprocessing, feature extraction, and feature matching.
The iris is the visible part of the human eye and has strong biological activity. For example, the size of the pupil will change with the intensity of light. When the human brain dies or the eyeball tissue is detached from the human body, the iris tissue will shrink completely, causing mydriasis.
These biological activities exist at the same time as human life phenomena, so it is impossible to replace the iris image of a living body with photos, videos, or iris of a corpse, thus ensuring the authenticity of physiological tissues.
Iris recognition technology is gradually changing our lives. Unlike other biometric technologies, iris recognition has high stability and uniqueness. It is formed after the fetus develops, and the iris remains unchanged for life, and it is not subject to the interference of the external environment.
Even if the iris texture of the left and right eyes of the same person are different. The fibrous structure of the iris is complex and rich in detail with great randomness, even if the cloning technology is used, it is impossible to replicate an iris.
The test results of the British National Physics Laboratory show that iris recognition has the lowest error rate among various biometric recognition methods.
There are about 266 reading points for iris recognition, while other traditional biometrics can only read 13-16, so iris has higher accuracy. Compared with fingerprint and face recognition, the false recognition rate of iris recognition is as low as one in a million.
The complex details of the iris make forgery almost impossible, and the biological characteristics of the iris can only be recognized in the case of a living body. It is impossible to successfully recognize iris images using photos and videos. Therefore, iris recognition is the most stable, accurate and safe biometric technology.
The iris is an internal organ that is visible from the outside, and qualified iris images can be obtained without being close to the collection device. Compared with fingerprints, hand shapes and other biological features that need to be touched and sensed, the recognition method is more clean and hygienic. It will not deface the imaging device and affect the recognition of others.
Application Areas of Iris Recognition Technology
- Financial sector
Due to the frequent occurrence of financial fraud and the theft of bank cards, there are certain vicious incidents in the bank’s security system. At the same time, with the continuous development of the financial industry, competition in the financial market has become increasingly fierce, and bank management has become more and more standardized. Safety issue has become a top priority.
In order to improve the level of security, banks have gradually introduced biometric technology for security upgrades. The application of iris recognition technology products in the banking industry is the trend of the times.
- Coal industry
When the workers go to the mine, the manager needs to know exactly the number of people entering the mine and specific information. In the past, traditional cards were used, and no matter who went down the well, they had to swipe the card. But it is not certain whether the person on the card is him, and it is difficult to guarantee that the number of people working in the mine is accurate.
There will also be problems if the face recognition system or fingerprint recognition system is used. Because coal mine workers often have a lot of coal ash on their faces and hands, it can cause inaccurate or unrecognized system recognition. In this case, iris recognition comes in handy to quickly obtain the user’s identity information.
- Electricity/nuclear power plant/military field
In order to improve the networking, intelligence, and informationization of power stations, and to improve management efficiency and safety, the current internationally advanced iris recognition technology can bring many conveniences.
On the one hand, it can realize the access control management of the passage and the personnel attendance management of the staff. On the other hand, according to the current status of substation equipment, the anti-misoperation locking system with iris identity authentication can be modified to greatly improve the safety of operation.
In recent years, iris recognition has received widespread attention from academia, industry, government, and the military, and is considered to be the popular trend of identity authentication in the future.
Countries around the world have increased their investment in the research and development of identity authentication technology. Countries such as India, Indonesia, Mexico have begun to use biometric technology with iris recognition as the core on their national ID cards, and established national basic biometric databases.
Undoubtedly, products using iris recognition will be seen everywhere in the future. As a core driving technology with transformative changes, it is expected that it can help the construction of smart cities in artificial intelligence and traditional industries in the future, and bring real convenience to people’s lives.
