With the development and maturity of technology, the way of identity verification is constantly improved and strengthened. From the initial manual comparison, to the large-scale penetration of biometric technology represented by fingerprint, face and iris into daily life, the age of no password is approaching.
Iris recognition technology is a kind of biometric identification technology based on iris in eyes. Compared with other biometric technologies, iris recognition technology has the characteristics of accuracy, stability, replicability, live detection and so on, and has great advantages in comprehensive security performance.
Iris recognition has a good market prospect
In fact, compared with face and fingerprint, iris recognition develops relatively late, but its development speed is very fast. According to the data, the global market size of biometric technology will increase from US $11.24 billion in 2015 to US $23.3 billion in 2020, with a compound annual growth rate of 15.7%. Among them, the market scale of iris recognition is expected to grow at an annual rate of 28.6% and reach US $2.45 billion by 2020. At present, iris recognition has a tendency to catch up with other biometrics.
With the promotion of the concept of smart home in China, the application of iris recognition has become more and more “civilian” and gradually penetrated into life. Mainly used in attendance and access control, suitable for places with high-level security needs, such as high-end residential buildings, office buildings, hotels, government agencies, etc.
Users can realize channel control, door opening and attendance management by scanning iris. Iris recognition is fast, without contact, and it is difficult to be counterfeited, which greatly improves the intelligence and security of management.
What are the difficulties in the application of iris recognition technology
Although iris recognition technology has many advantages and has been applied in various industries, at present, the overall market volume is still small and there is no large-scale application
Compared with face recognition, iris image acquisition is expensive. Because face recognition only needs the support of existing ordinary cameras, and iris acquisition needs professional hardware equipment to achieve. At present, the cost of iris equipment is still relatively expensive, and the iris hardware department still needs a long time. Therefore, it is still a long time for large-scale application of iris technology.
The recognition speed of iris and face is almost the same, but iris has high requirements for user interaction, such as imaging distance. At present, the technical level can reach the range of 40cm to 60cm, and the distance may gradually expand with the technology iteration in the future.
At the same time, the acquisition distance will be affected by different configuration of lens, and different configuration of camera lens will cause different imaging results. Due to different requirements of subdivision scene, there are different requirements for lens configuration. At present, the distance of acquisition can not be further, so it can not be applied to the field of large scene monitoring, but is generally used in airports, entrances and so on.
Finally, the iris has more requirements for the environment, which is easy to be affected by too bright light, and the recognition effect of the iris device in the outdoor will be worse.
Conclusion: Iris technology development has a fairly complete technical and industrial foundation, and has achieved phased results in the field of public security and is developing towards marketization. In practical applications, how to fuse low-quality biometric data to achieve high-quality recognition is the key to the future development of iris technology. Perhaps in the future, combining the advantages of face and iris, realizing multimodal recognition is another compromise.
