Resumen de: WO2025241290A1

A system for identity authentication on blockchain using NFTs includes a user interface, an identity NFT minting module, and a verifiable credential issuer module. The user interface allows a user to link a blockchain wallet and a credential wallet to the user interface and to provide an online service ID and requests the user to create signatures using a blockchain wallet private key and a credential wallet signing key. The identity NFT minting module verifies the online service ID and verifies the two signatures using the blockchain wallet address and the DID. The identity NFT minting module mints an identity NFT on a blockchain network, preserving the online service ID, the blockchain wallet address, and the DID in the identity NFT as metadata. The verifiable credential issuer module issues a verifiable credential to the user and triggers the identity NFT minting module for adding credential metadata to the identity NFT.

Resumen de: US2025365154A1

Systems and methods are directed to optimizing a security and recoverability trade-off generally associated with cryptocurrency master key storage. Exemplary embodiments provide a biometrically derived cryptographic seed using a measurement of one or more scale invariant biometric attributes associated with a user. The measured user biometric data is then processed into a repeatable biometric identifier and formatted into a (biometric) cryptographic seed, for derivation of a master extended private key, which may be stored in an HD wallet or used dynamically to conduct a blockchain transaction. The biometric seed and master key generation process may be facilitated by a mobile application responsive to a readout of biometric data from sensors integrated/associated with the mobile device. The captured biometric data may be cryptographically combined with a user-inputted password and/or an authentication data record wirelessly retrieved from an OTP card, to generate a cryptographic seed with greater security attributes.
