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 4):
The method according to  claim 3 , wherein the 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 comprises:\n in a case that the integrity rate corresponding to the characteristic matrix is less than 1, proportionally decreasing the weighting value of the characteristic matrix based on a missing rate corresponding to the characteristic matrix, wherein a sum of the integrity rate and the missing rate is equal to 1; in a case that the integrity rate corresponding to the characteristic matrix is equal to 1, increasing the weighting value of the characteristic matrix corresponding to the integrity rate equal to 1 based on a proportion of the initial weighting value of the characteristic matrix when the weighting value of the characteristic matrix corresponding to the integrity rate less than 1 is decreased proportionally, while ensuring the sum of all of the weighting values is equal to 1; in a case that each of the integrity rates corresponding to the characteristic matrixes is less than 1, regarding the characteristic matrix corresponding to the integrity rate greater than a preset threshold as the characteristic matrix corresponding to the integrity rate equal to 1; and in a case that each of the integrity rates corresponding to the characteristic matrixes is less than or equal to the preset threshold, returning to the step of collecting at least two types of biological characteristic identity information of the to-be-identified user, for re-collection.
