Abstract: A method and system for long-term authentication of non-fungible tokens is described. In various embodiments the system includes an off-chain storage system having one or more elements of identifying information for an object including at least one element that authenticates the object. In various embodiments the system further includes a blockchain network adapted for recording a non-fungible token located at a public address on a blockchain. In embodiments the minted non-fungible token includes at least an identification manifest and/or a hash of all or part of the elements of identifying information and/or a digital NFT certificate including a digital signature from a certifying authority and the hash of at least one of said elements of identifying information and/or of the identification manifest, such that the non-fungible token is independently authenticatable against said certifying authority and/or a corresponding validating authority and/or against the off-chain storage system.

Abstract: The invention relates to a device and method for the recognition of at least one individual and to the corresponding access control device and system and application thereof. The inventive recognition device comprises a one-piece integrated circuit which is produced by integrating the following elements on a silicon substrate: at least one biometric information sensor; means of processing said biometric information; cryptographic means which deliver at least one piece of encrypted data that is representative of at least one part of said biometric information and/or a corresponding piece of recognition information; and protection means that block access to data in transit, stored and/or processed in said one-piece integrated circuit in order to create a secure perimeter. In this way, the data exchanged by said sensor(s), processing means and cryptographic means, and particularly the aforementioned biometric information, are only saved in the one-piece integrated circuit and cannot be accessed from outside.
