Problems solved by technology

For any physiological recognition system, it is necessary to make a trade-off between the comparison performance and the allowable level. If the legitimate user is expected to be easy to use and the allowable level is increased (low FRR), the illegal user also has Higher probability (high FAR) passes the inspection, but if the allowable level (low FAR) is lowered in order to prevent illegal users, it is not easy for legitimate users (high FRR) to pass the inspection. Therefore, the physiological recognition system has a fixed However, it is difficult to provide convenience and high recognition rate at the same time. Regardless of whether the feature comparison criterion is set looser or stricter, there is a higher probability of misjudgment

Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0035] figure 1 According to a preferred embodiment of the present invention, a system for identifying identity by using multiple physiological information mixtures includes a light source 10 controlled to provide multi-wavelength light to irradiate a subject, and an image sensor 12 to capture images of the subject To generate the image signal Si, the identification module 14 extracts a variety of physiological features from the image, and analyzes and compares each physiological feature to generate a set of comparison scores Ci. The analysis and judgment unit 16 uses all the comparison scor...

Abstract

Disclosed are an identity recognition system and method based on hybrid biometric which capture an image of a subject that is projected by light of different wavelengths, extract various biometric information from the image, analyze and compare for each of the biometric information to generate a matching score, and determine an identity for the subject according to all of the matching scores. The system and method have higher recognition accuracy, lower false acceptance rate, lower false rejection rate, and higher flexibility.

Description

technical field [0001] The present invention relates to an identity identification system and method, in particular to a physiological identification system and method. Background technique [0002] Biometric identification is the use of unique physical characteristics of an individual, such as fingerprints, face, veins, iris or retina in the eye, to identify an individual. Fingerprint identification has been widely used, and it is often used as important evidence for the police to handle cases, but fingerprints have the risk of being easily copied. The physiological feature used in vein identification is the distribution of veins and blood vessels in the human hand. It is highly accurate and not easy to forge, and is unique. Sometimes it absorbs light and presents shadows, so it can be identified according to the characteristics formed by blood vessels such as interlacing, divergence, width, and color depth. However, vein identification will be affected by changes in the ...
