Abstract:
Provided are a method and device for authenticating an identity based on fusion of multiple biological characteristics. The method includes: collecting at least two types of biological characteristic identity information of a to-be-identified user; performing characteristic extraction on each type of the collected biological characteristic identify information, to obtain characteristic information corresponding to the type; establishing characteristic matrixes based on the characteristic information; performing normalization processing on each of the characteristic matrixes; performing dynamic weighting fusion on all of the normalized characteristic matrixes, to obtain a fused characteristic matrix; matching the fused characteristic matrix with a preset standard matrix, to obtain a matching score; and obtaining an identity identification result of the to-be-identified user based on a Bayesian decision model and the matching score.

Claim (Index 3):
The method according to  claim 1 , wherein the performing dynamic weighting fusion on all of the normalized characteristic matrixes to obtain a fused characteristic matrix comprises:\n allocating an initial weighting value to each of the normalized characteristic matrixes according to a preset weighting value allocation criteria, wherein a sum of all of the weighting values is equal to 1; calculating an integrity rate of the characteristic information corresponding to each of the characteristic matrixes; adjusting the weighting value of each of the characteristic matrixes based on the integrity rates while ensuring a sum of all of the weighting values is equal to 1; and performing weighting fusion on all of the normalized characteristic matrixes based on the adjusted weighting values, to obtain the fused characteristic matrix.
