Publication number: 20230410103Abstract: A zero knowledge proof purchase system and process using blockchain is disclosed. The system may comprise a customer device, a merchant system, an issuer system, and a blockchain network having a zero-knowledge proof (ZKP) smart contract. The system may implement a zero-knowledge proof algorithm haying a key generator function, a proof function, and a validate function. Each function may be configured to perform various tasks in the system to support and enable zero-knowledge proof purchases.Type: ApplicationFiled: July 17, 2023Publication date: December 21, 2023Inventors: ANDRAS FERENCZI, DALLAS L. GALE, NILESH Y. JADHAV, HARISH R. NAIK

Publication number: 20230385398Abstract: A single sign-on system using blockchain is disclosed. The single sign-on system may interconnect various organization systems over a peer-to-peer network, with each organization system having a blockchain node and an application programming interface (API). The blockchain node invokes and uses a smart contract to write registration credentials to the blockchain during a registration process. During a login process, the blockchain node invokes the smart contract to determine whether login credentials match stored login credentials in the blockchain. In response to matching login credentials, the API may generate a single sign-on token that can be used by a user device to access one or more organization systems connected over the network.Type: ApplicationFiled: August 14, 2023Publication date: November 30, 2023Inventors: Balaji Balaraman, Andras L. Ferenczi, Dallas L. Gale, Nilesh Yashavant Jadhav, Harish R. Naik
