Tina P. Srivastava has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20240129118
    Abstract: 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.

  • Publication number: 20240129119
    Abstract: 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.

  • Publication number: 20240121098
    Abstract: 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.

  • Publication number: 20240022420
    Abstract: 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, and may be used to provide authentication in addition to, or in lieu of, passwords or cryptographic tokens. Various use cases are disclosed, including: enrollment, authentication, establishing and using a secure communications channel, and cryptographically signing a message.

  • Publication number: 20240015152
    Abstract: A method for using biometric data to authenticate a subject as an individual whose biometric data has been previously obtained using a first transducer, the method utilizing computer processes including: generating shards from a digital electronic signal, provided as an output by a second transducer, such signal characterizing a biometric of the subject; causing distribution of the generated shards to an array of servers, so that the array of servers can store the generated shards and perform a data exchange process using a subset of the generated shards to develop information relating to authentication of the subject, where the authentication information includes a key of the subject, and processing the authentication information in a verification process to indicate whether the subject is authenticated as the individual.
