Match template protection within biometric security systems

A method of providing security in the context of multiple independent biometric security systems, the method comprising:

• utilizing a first processor associated with a first biometric security system to generate a first match template based on a first collection of biometric information;
• storing the first match template in a database associated with the first biometric security system;
• utilizing a second processor associated with a second biometric security system to generate a second match template based on a second collection of biometric information that is associated with a same biometric source as the first collection of biometric information;
• storing the second match template in a database associated with the second biometric security system;
• utilizing the first match template as a basis for providing security in association with the first biometric security system;
• and
• utilizing the second match template as a basis for providing security in association with the second biometric security system.

A method of providing security in the context of a biometric security system, the method comprising:

• obtaining a data representation of a first collection of biometric information;
• applying a transform function to the data representation of the first collection of biometric information to produce a match template;
• obtaining a data representation of a second collection of biometric information;
• generating an authentication model based on the data representation of the second collection of biometric information;
• comparing the authentication model to the match template to determine whether they are sufficiently related to be deemed matching;
• and
• granting at least one access right if they are sufficiently related to be deemed matching.

A method of preventing false aliases within a comparison database associated with a biometric security system, the method comprising:

• storing a plurality of match templates in the comparison database, each match template being associated with an alias;
• receiving from a biometric data collector a collection of biometric data, the collection of biometric data being associated with an alias that does not correspond to one of the plurality of match templates;
• applying a transform function to the first collection of biometric data to generate a proposed match template;
• comparing the proposed match template to the plurality of match templates;
• and
• granting or denying an ability to store the proposed match template in the comparison database based on whether or not the proposed match template corresponds to one or more of the plurality of match templates.
