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 13):
The method according to  claim 4 , wherein the standard matrix is reserved before an account is logged into for the first time using the method, and the standard matrix is reserved by:\n collecting at least two types of biological characteristic identity information of an account holder; performing characteristic extraction on each type of the at least two types of collected biological characteristic identity information, to obtain characteristic information corresponding to the type of the biological characteristic identify information; establishing characteristic matrixes based on the characteristic information, wherein there is a one-to-one correspondence among the biological characteristic identity information, the characteristic information and the characteristic matrixes; 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 corresponding to the account holder; and storing the fused characteristic matrix in a database as the standard matrix.
