Abstract:
1. A method of authenticating an identity of an object, comprising the steps of: enrolling the object in a computer readable data base by storing identification information associated with each object of a plurality of objects in the computer readable database; assigning a trust value to the identification information for each object to indicate a level of trust of the validity of the identification information, and storing the trust value in association with the identification information for each object; carrying out an authentication session by receiving an request for identification of an object, and receiving identification data of the object to be identified from a sensor into which the identification information was input; comparing the identification data received during the authentication session with the stored identification information received during the enrollment of the object to find a sufficient match therebetween; using the trust value of the identification information stored during enrollment to derive a score; using a predetermined trust value of the sensor to derive the score, where the trust value of the sensor is embedded in the sensor and signifies a level of confidence that the person inputting identification information therein is who they purport to be; using the trust value of the sensor and the trust value of the identification information, and defining the score so that the score is no larger than either of the trust value of the sensor or the trust value of the identification information; and providing a response indicating a sufficient match, and providing the score indicating a probability that the object is what the object is purported to be.
