Anonymous biometric verification

摘要

The present invention discloses an anonymous biometric verification system and method. In an embodiment of the invention, the system comprises a non-anonymous sector that retrieves biometric data (probes) by using biometric client(s). A unique identifier (“token”) is retrieved from a database that contains biographic and demographic data associated to the token, but without comprising the biographic or demographic data. The biometric data in form of template(s) along with the token are then sent via a cloud network to an anonymous sector. A query router, located at the non-anonymous sector may receive probes with the token and send them to one or more biometric query engine(s), wherein query engine(s) may either work in stripped or mirrored operation mode. Query engine(s) may search for location of template(s) in a templates database linked to a query search engine.

1. A method of biometrically verifying identification of an individual anonymously, the method comprising:
receiving, at a query engine in an anonymous biometric identity management sector, a biometric probe from the individual and a token associated with the individual, wherein the anonymous biometric identity management sector has no knowledge of or access to any biographic, demographic, or identifying information of the individual; retrieving, at the query engine, a biometric template corresponding to the token, wherein the biometric template is retrieved from a template database in the anonymous biometric identity management sector; comparing the biometric probe to the biometric template; computing a score based on the comparing; wherein the token is a unique identifier which carries no demographic or biographic information of the individual, and further comprising receiving by a query router at least one biometric probe and a token; selecting a query engine; transmitting the biometric probe to the query engine; receiving the score from the query engine; determining a verification result from the score; and transmitting the verification result to a non-anonymous biometric identity management sector.
