Abstract:
A system for authorizing a user to a secure site, the system comprising:(a) a memory unit for storing information including a stored voice print and an identity of each of a plurality of individuals having access to the secured site, said stored voice print of each of said plurality of individuals being generated from a corresponding voice data thereof; (b) a first input device for inputting user information for verifying that the user identifies him- or herself as a specific individual among said plurality of individuals; (c) a second input device for inputting temporary voice data of the user; (d) a first processing unit for generating a temporary voice print from said temporary voice data received from said second input device; and (e) a second processing unit for comparing said temporary voice print to said stored voice print of each of at least a portion of said plurality of individuals to provide a distortion level between said temporary voice print and each said stored voice print of each said individual in said at least a portion of said plurality of individuals, at least said portion of said plurality of individuals including said specific individual, whereby said distortion level is smallest when the user and said specific individual are the same person and less than said distortion level between said temporary voice print and said stored voice print of all other individuals of at least said portion of said plurality of individuals, the user being granted access to the secured site based on said smallest distortion level; wherein said comparing is effected by a voice authentication algorithm selected from the group consisting of a text-dependent and a text-independent voice authentication algorithm.
