Publication number: 20240129118Abstract: A device generates a biometric public key for an individual based on both the individual's biometric data and a secret S, in a manner that verifiably characterizes both while tending to prevent recovery of either. The biometric data has a Sparse Representation and is encoded in a manner to include a component of noise, such that it is challenging to identify which locations are actually encoded features. Accordingly, the biometric data are encoded as a vector by choosing marker at locations where features are present and, where features are not present, choosing noisy data. The noisy data may be chaff bit values selected collectively from a group of (a) random values and (b) independent and identically distributed values. The biometric public key may be later used to authenticate a subject purporting to be the individual, using a computing facility that need not rely on a hardware root of trust.Type: ApplicationFiled: October 24, 2023Publication date: April 18, 2024Inventors: Charles H. Herder III, Tina P. Srivastava

Publication number: 20240129119Abstract: A device, method, and computer readable storage medium generate a biometric public key for an individual based on both the individual's biometric data and a secret, in a manner that verifiably characterizes both while tending to prevent recovery of either by anyone other than the individual. The biometric public key may be later used to authenticate a subject purporting to be the individual, using a computing facility that need not rely on a hardware root of trust. Such biometric public keys may be distributed without compromising the individual's biometric data. In operation, a confident subset of a set of biometric values of the subject is extracted, including by performing a transform of the set of biometric values. The transform may variously be a Gabor transform, a wavelet transform, processing by a machine learning system, etc.Type: ApplicationFiled: October 27, 2023Publication date: April 18, 2024Inventors: Charles H. Herder, III, Tina P. Srivastava

Publication number: 20240121098Abstract: A system for using biometric data to authenticate a subject as an individual whose biometric data has been previously obtained. A second transducer has a digital electronic signal output characterizing a biometric of the subject; a second computing facility to receive the digital electronic signal; and an array of servers. These components implement processes including causing: generation of authentication shards from the digital electronic signal and distribution of the authentication shards to the array of servers; storing by a subset of the array of servers the authentication shards; performing a data exchange process using a subset of the authentication shards to develop authentication information relating to the subject; processing of the authentication information to synthesize a signed challenge of the subject; and processing of the synthesized signed challenge in a verification process to indicate whether the subject is authenticated as the individual. A related enrollment system is also provided.Type: ApplicationFiled: December 7, 2023Publication date: April 11, 2024Inventors: Charles H. Herder III, Tina P. Srivastava, Young Hyun Kwon
