Zusammenfassung: | A method for processing a transaction, wherein the method is implemented by an electronic device for processing transactions, accessible via a communication network. The includes a transaction processing phase. The transaction processing phase: obtaining a contextual cryptographic fingerprint, previously generated during an authentication of a user on a communication terminal; verifying validity of the contextual cryptographic fingerprint in a blockchain including a set of cryptographic fingerprints; and validating a transaction when the verifying the validity of the contextual cryptographic fingerprint in a blockchain is positive. |
