In December 2013, the Human Resources and Social Security Bureau of Shanghai Putuo District and Beijing Zhineng Yitong Technology Co., Ltd. signed a product procurement contract. It is the first in China to use finger vein identification technology for work injury insurance, for work injury identification and work ability Qualification certification of insured persons in the appraisal business.
Finger vein collection and certification equipment will be equipped in Shanghai Putuo District Work Injury Recognition Window, Work Ability Appraisal Window, Work Injury Recognition Designated Hospitals, and Work Ability Appraisal Hospitals to ensure that work injury procedures, work injury recognition, and work ability appraisal are the treatment personnel themselves. The introduction of finger vein recognition technology will effectively standardize the certification and appraisal of work-related injury insurance, and ensure the safe and reasonable use of work-related injury insurance funds.
Principles of Finger Vein Recognition Technology
Finger vein recognition technology confirms the identity of the person through the vein texture recognition of the finger. The hypoxic hemoglobin in the veins can absorb near-infrared rays. When the near-infrared rays are irradiated to the finger, a small camera with near-infrared sensitivity is pointed at the finger to obtain an image of the vein pattern.
When verifying the identity of the finger veins, the finger is first irradiated with near-infrared rays, so that the veins of the finger veins are displayed under near-infrared rays, and these vein textures are obtained by a dedicated near-infrared ultra-small camera, and the finger vein information is saved with the system Perform matching, instant verification and identification.
Finger vein flow chart
The process of the finger vein system is divided into the following four steps:
(1) Vein scanning: LED emits near-infrared rays on one side of the finger, and transmits through the finger, and on the other side of the finger, the camera shoots vein images;
(2) Image correction: adjust the position and angle of the image to make it meet the specifications;
(3) Feature extraction: Based on the image obtained above, extract the vein distribution image to obtain a feature map;
(4) Image comparison and matching: Compare the feature map obtained above with the original template in the database, and calculate the correlation. Pass if it matches, and reject if it doesn’t match.
Technical advantages
Finger vein recognitionThe technology innovatively uses industry-leading light propagation technology to perform finger vein comparison and recognition. When the near-infrared rays pass through a human finger, part of the rays will be absorbed by hemoglobin in the blood vessel, thereby capturing the unique finger vein pattern, and then comparing it with the pre-registered finger vein pattern to identify the individual.
The patented light transmission technology can ensure that high-contrast finger vein images can be captured without being affected by any defects and blemishes such as wrinkles, texture, roughness, and dry humidity on the skin surface. Because finger vein pattern comparison only requires a small amount of biometric data, it is possible to develop the world’s fastest and most accurate personal identification system, and use it in a compact, friendly interface, and affordable personal identification device. Effective application.
Finger vein recognition technology is extremely difficult to forge and tamper with, and it is highly anti-counterfeit. Login is simple and has good operability. All indicators have high precision: false rejection rate (FRR) 0.01%; false recognition rate (FAR) 0.0001%. The user’s psychological resistance is low, and it is not affected by the external environment such as age, occupation, heart, humidity, temperature, etc., and it can be highly accurately identified with a light touch when using the finger, and the speed is fast, and the whole process is less than one second. .
Finger vein authentication technology uses the vein pattern image obtained after the near-infrared rays penetrate the finger to perform personal identification. It is the world’s most cutting-edge biometric technology with high precision and high speed. Among the various biometric technologies, because they use the internal characteristics of the creatures that cannot be seen from the outside, they are attracting attention as a second-generation biometric technology with high anti-counterfeiting properties.
