In today's world, identification is becoming more and more important in everyday life. Whether you go to the bank for business, or you fly by plane, or even open a door, you need to verify your identity. Traditional authentication methods include identification, such as documents, keys, user names, and passwords. With the help of foreign substances, once a token or password is stolen or forgotten, its identity is easily impersonated or replaced by others.
The non-contact palmprint recognition system uses the person itself to prove the identity. It uses the uniqueness of the human features to be copied, and it targets the collection of fingerprint, palmprint, human face, iris and other recognition technologies that people are familiar with. Features are easy to copy, palms are easy to peel, injury, face shape instability, high requirements on the ambient light source, through the active irradiation of the near-infrared light source, the use of human hemoglobin to absorb specific infrared light band characteristics, access to the human subcutaneous vein network infrared image.
The system uses an embedded processor and a multispectral image acquisition device as its core hardware. It has a dual-object image sensor and multi-spectral imaging technology. It has high-definition palmprint capture, and palm subcutaneous vein dual-body biometrics and biometric authentication. Its non-contact acquisition method completely overcomes hidden dangers such as fingerprint leakage and hygiene problems brought by series of contact biometric identification products such as fingerprints, and has the advantages of being portable and available everywhere. In the demonstration system, the database stores the features of the palm veins and palm veins of 500 people. As long as the visitor reaches out to identify, the system can identify the visitor in only one second.
The non-contact palmprint palm recognition system is exquisitely designed and can be widely used in electronic transactions such as access control attendance, ATM deposits and withdrawals, and online banking. It can also be used in hotel applications such as hotel registration, customs clearance and outbound management. Completely replace traditional identification methods such as passwords and IC cards. According to user requirements, it can provide a single point or networked multi-point access control system that divides physical security areas, which greatly improves the overall community safety and reduces the occurrence of criminal events. As a high-precision identity product, the non-contact palmprint recognition system is closely related to our life and work.
