With the continuous progress and development of society, people pay more attention to public health and personal hygiene in their daily lives. Therefore, the biometric identification technology used in the public environment needs to ensure that the device will not become a means of transmission of bacteria and diseases.
Undoubtedly, the non-contact biometric identification system can provide users with better user experience and hygiene assurance, which greatly improves the user acceptance of biometric identification technology, and also reduces the hygiene of individual users. The possibility of deliberately reducing the security of the system. For example, during the use of the fingerprint identification system, it was discovered that individual users only used their fingertips for registration and identification in order to avoid large-area contact between their fingers and the device. Obviously, this way of use will greatly increase the possibility of misunderstanding and artificially lead to a reduction in the overall safety of the system. In addition, the non-contact biometric identification system also prevents users from leaving marks during use, can effectively prevent users from divulging personal biometric information, and prevent professional criminals from copying personal biometrics to conduct criminal activities. The non-contact biometric recognition system can greatly improve the safety performance of the system while improving the ease of use and user acceptance.
The contactless biometric digital identification technology means that the user can complete the collection, analysis and judgment of human biometrics without direct contact with the system during use. For example, face recognition and iris recognition are contactless biometric technologies.
Face recognition is a biometric technology that uses facial feature information to identify people. The advantages of face recognition are fast and "non-contact", which can greatly improve the response speed of the system while avoiding the hidden sanitary hazards caused by machine contact.
Iris recognition is a technology that uses the features of the iris in the human eye to verify identity. It determines the identity of people by comparing the similarities between the features of the iris images. Iris recognition is unique in biometrics and has a high level of security. For other biometric technologies, iris recognition is a non-contact recognition of living organisms.
