Problems solved by technology

However, this method does not use microelectrode arrays, the complexity and completeness of the information collected is limited, and it is not suitable for certification
[0005] In summary, although smart authentication has been studied to a certain extent, there is no report in the literature that an intelligent authentication device based on finger bioimpedance characteristics can be realized.

Description

technical field [0001] The invention relates to a finger intelligent authentication device in the field of intelligent authentication, in particular to an intelligent authentication device capable of realizing finger bio-impedance characteristics. Background technique [0002] In recent years, more and more attention has been paid to the research and development of intelligent authentication, especially the authentication issues that can adapt to different application backgrounds and have high security. Traditional fingerprint smart authentication devices are identified by image information such as fingerprints. Fingerprints are easily affected by finger pollutants, resulting in relatively low security and ease of use, and are subject to some limitations in practical applications. [0003] Chinese application number CN200810174366.5, application publication number CN101721208A, the patent discloses a bio-impedance measurement device for multiple limb segments of the human bo...
