Problems solved by technology

However, this method is still based on the identification of the physical characteristics of the fingerprint, which cannot avoid the possibility that the second person can obtain pattern data by cutting off or stealing the fingerprint for camouflage.

Embodiment 1

[0020] Embodiment 1: The multi-feature living body recognition device includes an extraction part, an information processing part and a recognition part, and the extraction part is used to extract infrared microscopic image information from the surface of a living body, and is mainly composed of an infrared microscopic thermal imaging system; The information processing part is used to correct and automatically identify the extracted infrared microscopic image information to obtain accurate inherent information of the living body; the identification part is used to compare the inherent information of the living body with the pre-stored information to obtain Identify living organisms.

Embodiment 2

[0021] Embodiment 2: This embodiment is the same as Embodiment 1, please refer to figure 1 . The multi-feature living body identification device is composed of an infrared microscopic section 101 , a biological information collection section 102 and a biological information processing and identification section 103 . The infrared microscopic part 101 receives the infrared rays radiated from the living body, and obtains enlarged and microscopic image information through multiple groups of lenses, wherein the lenses are made of materials that can transmit infrared rays, such as germanium, calcium fluoride, silicon dioxide, etc. Wait. The biological information collection part 102 is an infrared CCD camera, which converts the infrared image information obtained by the infrared microscope part 101 into digital image information. The biological information processing and identification part 103 performs correction, automatic identification and other processing on the image inform...

Embodiment 3

[0028] Embodiment 3: The operation steps of this multi-feature living body recognition method are as follows:

[0029] (1) Extract infrared microscopic image information from the surface of the living body;

[0030] (2) Extract various information from the extracted infrared microscopic image, so as to obtain inherent information about the living body;

[0031] (3) The information inherent to the living body is compared with the information stored in advance.

Abstract

The invention relates to multi-character vivo identification method and device. On the basis that vivo skin displays sweat gland distribution, skin patterns (such as fingerprint) and other information under an infrared micro imaging system, an infrared detector detects vivo sweat gland information, the skin patterns (such as fingerprint) and other information which are acquired by the infrared micro imaging system and the vivo information with the presorted information are compared. The sweat gland imaging of the infrared micro imaging system is based on the temperature difference of the vivo surface skin and the vivo sweat gland, so single vivo can be identified by the method at higher safety so as to prevent the illegal camouflage.

Description

technical field [0001] The invention relates to a method and a device for identifying a living body by utilizing various biological information of the living body. Background technique [0002] With the development of the times, unreliable identification and authentication have caused huge losses in business and property. Biometric identification methods that can replace passwords have become one of the methods that can well solve identity authentication problems, such as recognizing physical characteristics of voice, retina and fingerprints. However, such an identification device has security problems because the pattern data can be obtained and imitated by a second person. In fact, the second person can simply cut out physical characteristics from the first person and can masquerade as the first person. [0003] In order to eliminate the above disadvantages, a method and apparatus for living body recognition as shown below have been disclosed. [0004] Japanese patent C...
