Abstract
A method, system and computer program product for ensuring a biometric template is associated with a live entity comprising an intelligent biometric scanner in processing communications with a computer system and a security token. The intelligent biometric scanner applies a data transformation to an inputted entity biometric sample and a biometric challenge supplied by a security token. The transformed biometric sample is processed by a computer system using the transformed biometric challenge resulting in an transformed entity biometric template which will not match an enrollment template stored inside the security token until the transformation is reversed by the intelligent biometric scanner. Embodiment of the invention are also disclosed which does not require the use of a challenge.
Claims55
A method for ensuring an entity biometric template is associated with a live entity, comprising:
- generating, via a security token, a transformed biometric sample by applying a data transformation to at least a portion of a biometric sample received from a live entity, wherein said data transformation comprises at least a pixel inversion, a translation, a rotation, a mirror image or a coordinate system deviation;
- sending, via the security token, the transformed biometric sample to a computer that generates a transformed entity biometric template by extracting one or more biometric features included in said transformed biometric sample and sends the transformed entity biometric template to the security token;
- reversing, via the security token, said data transformation incorporated into said transformed entity biometric template;
- and
- generating, via the security token, an entity biometric template before attempting to compare said entity biometric template to an enrollment biometric template.
