4. Huizhou Kyle Optoelectronics Co., Ltd., a wholly-owned subsidiary of Shuobed (300322), is used to expand the production scale of high-pixel image sensor modules and invest in the research and development of new generation biometric sensor modules. , design and manufacturing (including fingerprint recognition sensors, iris recognition sensors, etc.) and newly invested sensor modules and application integration system R&D centers.
5. Xinkaipu (300248): The company is one of the earliest domestic enterprises engaged in the research, development, production and integration of smart card systems. At the beginning of this year, the company stated on the investor relations interactive platform that the company’s identity recognition technology mainly focuses on fingerprint and face recognition. Fingerprint recognition technology is currently relatively mature, and companies mainly apply it in attendance and access control. Facial recognition technology has a high technical threshold and broad future application space. The company is currently independently developing this technology. Extended information
Iris recognition technology also has several major advantages:
1. Stability. Seven months after a person is born, the iris is basically stable and remains unchanged throughout life;
2. Uniqueness. Everyone's left eye and right iris are different, even identical twins have different iris textures;
3. Non-contact. Compared with other biometric authentication technologies such as fingerprints, finger veins, palm veins, etc., iris recognition is more flexible and convenient to use;
4. It has natural living body detection advantages. Compared with the currently popular fingerprint and face recognition technologies, iris recognition has many advantages in prosthesis attacks: the cost of replicating fingerprints is low, and many fingerprint modules can be easily broken using fingerprint sleeves; face recognition, especially people under visible light, The accuracy of face recognition is low and it is not suitable for precise positioning, let alone the use of disguises, human skin masks, and twins.
