Identity identification apparatus and method thereof

Abstract

The invention relates to the biological identification technology field and especially relates to an identity identification apparatus and a method thereof. The identity identification apparatus comprises a biological characteristic signal acquisition module, a biological characteristic extraction module and a biological characteristic identification module. The biological characteristic signal acquisition module is used for collecting a fingerprint image and a finger portion group delay curve. The biological characteristic extraction module is used for extracting a fingerprint characteristic value and a group delay characteristic value respectively according to the fingerprint image and the finger portion group delay curve. The biological characteristic identification module is used for constructing an identity identification model through a training sample set and carrying out cross validation on the extracted fingerprint characteristic value, the group delay characteristic value and the identity identification model through using a convolution nerve network algorithm so as to realize identity identification of a user. In the invention, through collecting a fingerprint characteristic of the user and finger portion dielectric spectrum characteristic information, the identity identification is performed; and through using a multimodal fusion identity identification algorithm based on a convolution nerve network, the identity identification is performed and identity identification accuracy is increased.

Description

technical field [0001] The invention relates to the technical field of biological identification, in particular to an identification device and method. Background technique [0002] With the rapid development of science and technology, the degree of informatization of the whole society is increasing day by day, and the probability of information leakage is increasing day by day. Once such information is collected and fraudulently used by criminals, it will bring significant economic loss to the fraudulently used person, and even endanger the safety of others and the entire society in severe cases. An important means of information protection is the use of identification technology. Traditional identification technologies are generally based on IC radio frequency cards, static passwords or dynamic passwords, etc., which have security loopholes such as easy loss, easy forgetting, and easy replacement. [0003] Biometric technology refers to a kind of identification technolog...
