  • Publication number: 20230131437
    Abstract: Provided is a method for authentication. The method may include receiving first password data, first biometric input data, and first secret key data. A second secret key may be generated based on the first secret key and the first password. Fuzzy extractor helper data may be generated based on the first biometric input and the second secret key. The fuzzy extractor helper data and the first secret key may be stored. The user may be authenticated based on an attempted password and/or a second biometric input. A system and computer program product are also disclosed.

  • Patent number: 11601407
    Abstract: Systems, methods, and computing device readable media for implementing fast oblivious transfer between two computing devices may improve data security and computational efficiency. The various aspects may use random oracles with or without key agreements to improve the security of oblivious transfer key exchanges. Some techniques may include public/private key strategies for oblivious transfer, while other techniques may use key agreements to achieve simultaneous and efficient cryptographic key exchange.
