System and method for anonymous biometrics analysis

摘要

A system receives an identification number from a subject. The system retrieves a biometric measurement from a database using the identification number. The database includes biometric measurements of a plurality of subjects. Each biometric measurement is determined from a location of a particular subject's body, each biometric measurement is associated with a particular identification number, and each particular identification number is associated with a particular subject. When the use of the identification number results in a retrieval of a biometric measurement from the biometric database, the system searches a plurality of locations on the subject and takes biometric measurements at the locations, compares the retrieved biometric measurement from the biometric database with the biometric measurements of the subject, and indicates that the retrieved biometric measurement from the biometric database matches one or more of the biometric measurements from the subject or that the retrieved biometric measurement from the biometric database does not match any of the biometric measurements from the subject. In an embodiment, the system is used for verification purposes, not identification purposes.

主权项

1. A system comprising:
a computer processor configured to:
receive an identification number from a subject;select a plurality of body locations on the subject at which to take biometric measurements of the subject and store the biometric measurements in a database, wherein the body locations are selected randomly; retrieve a biometric measurement from the database using the identification number, wherein the database comprises biometric measurements of a plurality of subjects, wherein each biometric measurement is determined from a location of a particular subject's body, wherein each biometric measurement is associated with a particular identification number, and wherein each particular identification number is associated with a particular subject; and when the use of the identification number results in a retrieval of the biometric measurement from the database, wherein the retrieved biometric measurement from the database is from a random location on the subject such that the retrieved biometric measurement cannot be used to identify the subject by matching to any other databases, anonymously analyze the biometric measurements by:
searching the plurality of body locations on the subject and taking biometric measurements at the locations such that any biometric measurement taken from the subject is generic and can verify the subject as one who previously presented the biometric measurement for storage in the system, and such that none of the biometric measurements taken from the subject can function as a signature to identify the subject;comparing the retrieved biometric measurement from the database with the biometric measurements of the subject; andindicating that the retrieved biometric measurement from the database matches one or more of the biometric measurements from the subject or that the retrieved biometric measurement from the database does not match any of the biometric measurements from the subject.
