Abstract

The invention discloses a fingerprint and finger vein combined recognition algorithm, which comprises the following steps of: firstly, retrieving N candidate users by utilizing a fingerprint feature point-based local surrounding point relative position and direction field similarity algorithm, and carrying out matching by using a finger vein recognition method based on combination of feature points and binary images; Experiments show that based on a fingerprint feature point local surrounding point relative position direction field similarity algorithm, the algorithm is good in stability, highin anti-interference capability and high in retrieval speed. The finger vein recognition algorithm based on the combination of the feature points and the binary image is stable. Under the condition that the false recognition rate is certain, the recognition performance of the fingerprint and finger vein combined recognition algorithm is obviously higher than that of a traditional fingerprint andfinger vein single-mode recognition algorithm; And the identification efficiency is also obviously improved.

Description

technical field [0001] The invention relates to the technical field of biological feature identification and information security, and more specifically relates to a fingerprint fast retrieval method and a finger vein identification method based on the combination of feature points and binary images. Background technique [0002] In today's information age, how to accurately identify a person's identity and protect information security has become a key social problem that must be solved. Traditional identification is more and more difficult to meet the needs of the society because it is very easy to forge and lose. The most convenient and safe solution at present is undoubtedly biometric technology. It is not only simple and fast, but also uses it for identity identification, which is safe, reliable and accurate. At the same time, it is easier to cooperate with computer security, monitoring, and management system integration to realize data information management. This is ...
