Palm recognition system

In real life, people often get into trouble because they forgot their passwords, or because of the loss of ID cards and other types of documents, we don’t need to worry about forgetting passwords to get money and losing ID cards. Information leakage. Because our hands are passwords and can prove identity. This is the biometric technology, living human identity card in the 21st century.

In today's world, identification is becoming more and more important in everyday life. Whether you go to a bank for business, or take a 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 palm recognition system uses the person itself to prove the identity. It uses the uniqueness of the human character to be non-replicable, and it is difficult to capture fingerprints, palm prints, human faces, and irises that people are familiar with. It is copied, the palm is easy to peel, injury, face shape is unstable, the environmental light source requires higher factors, through the active illumination of the near-infrared light source, using the characteristics of human hemoglobin to absorb infrared light in a specific band, to obtain the infrared image of the human subcutaneous vein network.

The system uses an embedded processor and a multi-spectral image acquisition device as its core hardware. It has a dual-object image sensor and multi-spectral imaging technology. It features high-definition acquisition of palm prints, and dual human body biometrics and live authentication of the palmar subcutaneous vein. 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 of the hand of 500 people. Visitors only need to reach out and identify the system. The system can identify the visitor in only one second.

The non-contact 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, etc. 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 security and reduces the occurrence of criminal events. As a high-precision identification product, the contactless palm recognition system is closely related to our life and work.

The non-contact palm pattern recognition product adopts high-performance embedded processor to collect, process and identify online. The authentication is fast and accurate. The comparison speed (1:N, N<100) is less than 1.5 seconds. At the same time, the unique dual image sensor and dual-band spectral imaging technology are adopted to simultaneously acquire palmprint and palmar vein image analysis and recognition, greatly improving the accuracy of single feature recognition, and introducing palmar features, with traditional biometric products. Live authentication features that are not available can be used for high security level identification occasions.
