摘要
Disclosed in an embodiment of the present invention is a method for authenticating identify by means of fusion of multiple biological characteristics, which allows identity authentication to be carried out by using more than two types of biological characteristic identity information, thereby providing a higher identification accuracy. The method in the embodiment of the present invention comprises: collecting at least two types of biological characteristic identity information of a user to be identified; carrying out characteristic extraction on the at least two types of collected biological characteristic identity information, so as to obtain corresponding characteristic information; establishing characteristic matrixes according to the characteristic information, the biological characteristic identity information, the characteristic information and the characteristic matrixes being in a one-to-one correspondence; respectively carrying out normalization processing on all the characteristic matrixes; carrying out dynamic weighting fusion on all the normalized characteristic matrixes, so as to obtain a fused characteristic matrix; carrying out matching according to the fused characteristic matrix and a preset corresponding standard matrix, so as to obtain a corresponding matching score; and obtaining an identity identification result of the user to be identified according to a Bayesian decision model and the matching score. An embodiment of the present invention also provides a device for authenticating identify by means of fusion of multiple biological characteristics.
