Fire-eye golden eye - iris recognition

Recently, relying on the country's top iris recognition technology, an instrument called "long-distance multimodal biometrics" was officially put into production, which can accurately identify the iris and face information of personnel within 0.2 seconds at a distance of 1 meter.

"At present, most companies can only do 25-40 cm of close iris recognition." The relevant person in charge of Shaanxi Guardian Star Information Technology Co., Ltd. said in a recent interview.

So, what are the advantages of iris recognition?

Face iris recognition

At present, biometric technology has been relatively mature, and the recognition accuracy and speed are at a high level. At present, the development of the market is relatively mature, and the most widely used biometric technology is fingerprint recognition, face recognition and iris recognition.

Fingerprint recognition because it is easier to be copied, and it is easy to affect the recognition effect because the hand points out sweat, dirt or water, wearing gloves, etc., plus fingerprint recognition needs to contact the machine, although it still occupies most of the share in the market, but it has begun to be replaced by the non-contact recognition mode of face recognition and iris recognition.

For face recognition technology, the biggest challenge now is that plastic surgery and makeup technology are becoming more and more developed, ugly women becoming beautiful women are no longer a miracle, but commonplace, face change plastic surgery is also a matter of minutes. In modern society, the incident of changing a face for an ID card can hide and hide from legal sanctions is no longer new. It is worth mentioning that with age, the face will also change. This means that after a stage, everyone must re-collect new face information. In the long run, it is also more inconvenient to maintain and use. The iris recognition technology is based on the iris in the eye for identity recognition of biometric recognition technology, compared with fingerprints, face recognition and other biometric recognition methods, with higher recognition accuracy, lower misidentification rate, no need for repeated registration, non-contact and extremely difficult to forge and other advantages, is considered to be in addition to DNA "the most reliable biometric technology".

"The circular area between the black pupil and the white sclera of a person is the iris, which can show rich texture characteristics under infrared light conditions, and the iris texture is basically stable after birth, almost unchanged for life, and each biological individual has uniqueness." The relevant person in charge said that the iris has unique, anti-counterfeiting and stable biological characteristics, which is very suitable for identity recognition.

Accurately finding people in a large crowd is a huge advantage of iris recognition technology. In general, the greater the number of traits that describe a person, the easier it is for the person to be identified in a large-scale population. According to the relevant person in charge, the stable feature points of the face are 30, the fingerprint is 100, and the iris has more than 200. This means that the difference in probability of a person accurately found in the database by 3 ways of identifying them in order of magnitude. The matching capacity of face recognition, fingerprint recognition and iris recognition is 10,000, 100,000 and 1 million, respectively. In other words, if you want to accurately find a person in the surveillance video, the 10,000 population base can be identified with a face, below 100,000 people can be identified by fingerprints, and the person in the 1 million people should be identified by iris. On the contrary, if face recognition is used to find people among 1 million people, the accuracy rate will drop significantly, and the misidentification rate will increase a lot. ”

Taking the iris recognition technology used in the security inspection of Singapore Garbo Airport as an example, the recognition accuracy of the iris recognition technology is as high as 99.9%, and the identity authentication of passengers can be completed in less than one second. Passengers can link their biometric information to their travel documents when checking in and can complete fast boarding directly through the security check and the biometric identification system at the gate if they do not need to check in baggage, without having to show their boarding passes, passports or travel documents.

At the same time, the biometric system will accurately determine the identity of passengers, through the comparison of passenger information collected at the security check and the boarding gate, to ensure the validity of the identity of boarding passengers, fraudulent use of documents, forged documents and other violations will be hidden, thereby greatly improving the safety of civil aviation transportation. From this perspective, as the number of passengers continues to grow, biometrics will increasingly become the best solution for airlines and airports to automate identity checks.

In fact, in addition to Atlanta Airport, Orlando Airport in the United States, Brisbane Airport in Australia, Boston Logan Airport, etc. have also announced the use of biometric technology for security screening. In the mainland, Beijing Capital Airport has applied biometric technology to airport work since 2009, and at present, Taiwan Taoyuan Airport, Nanjing Lukou Airport, Shenzhen Baoan Airport, Yinchuan Airport, Guangzhou Baiyun Airport and other security inspection work have introduced biometric technology. The number of airports applying biometrics has increased dramatically, with a blowout trend. "The technology is equipped with a high-definition imaging system, which uses an efficient core algorithm to quickly locate a clear iris texture area and extract a feature code with high discrimination. In an environment that maintains the same accuracy as the traditional static iris recognition, the user only needs to glance at the front of the device to complete the recognition, without too much cooperation, and the sense of experience is greatly improved. The relevant person in charge of the marketing manager of Guardian Star Technology was introduced.

As the main research and application of biometric technology industry, the domestic security industry has also launched corresponding solutions. For example, Guardian Star has launched solutions for various industries using biometric technology, including iris recognition, face recognition and id identification, etc., covering biometrics, identity and other technologies to important regulatory areas and each passenger, effectively helping passengers to easily and quickly pass through security checks, from security checks to boarding, barrier-free passage throughout the whole process, to ensure the safe boarding of the real-name system.

The introduction of biometric technology can make airport security faster and safer, with the establishment of airport intelligent security system system, biometric technology will better escort airport security.
