Abstract
An NFT (Non-Fungible Token) issuing method according to the present disclosure includes receiving a selection of a first artwork in which a watermark is embedded, authenticating, in reference to the watermark and information concerning a user who selects the first artwork, whether or not the user is an artist of the first artwork, and generating a first NFT indicating the first artwork when the authenticating succeeds. Embodiments of the present disclosure can prevent NFT conversion of a digital artwork by a person who does not have a legitimate right.
Claims18
A method of authentication, comprising:
- receiving a selection of a first artwork in which a watermark is embedded;
- authenticating, in reference to the watermark and information concerning a user who selects the first artwork, whether or not the user is an artist of the first artwork;
- generating a first Non-Fungible Token indicating the first artwork when the authenticating succeeds;
- receiving a second artwork;
- generating a project including the first artwork and the second artwork;
- and
- generating Verifiable Credentials of the project, the Verifiable Credentials including a first electronic signature generated by encrypting an identifier of a Decentralized Identity document of the project by a private key of the artist of the first artwork,
- wherein authentication of the user who selects the first artwork is considered to have succeeded when the first electronic signature is able to be decrypted by a public key of the user, and the authenticating is considered to have failed when the first electronic signature is not able to be decrypted by the public key of the user.
A computer, comprising:
- a processor;
- and
- a memory storing instructions that, when executed by the processor, cause the computer to:
- receive a selection of a first artwork in which a watermark is embedded;
- authenticate, in reference to the watermark and information concerning a user who selects the first artwork, whether or not the user is an artist of the first artwork;
- generate a first Non-Fungible Token indicating the first artwork when the authenticating succeeds;
- receive a second artwork;
- and
- generate a project including the first artwork and the second artwork;
- generate Verifiable Credentials of the project, the Verifiable Credentials including a first electronic signature generated by encrypting an identifier of a Decentralized Identity document of the project by a private key of the artist of the first artwork,
- wherein authentication of the user who selects the first artwork is considered to have succeeded when the first electronic signature is able to be decrypted by a public key of the user, and the authenticating is considered to have failed when the first electronic signature is not able to be decrypted by the public key of the user.
A non-transitory computer-readable medium storing a program that, when executed by a computer, causes the computer to:
- receive a selection of a first artwork in which a watermark is embedded;
- authenticate, in reference to the watermark and information concerning a user who selects the first artwork, whether or not the user is an artist of the first artwork;
- generate a first Non-Fungible Token indicating the first artwork when the authenticating succeeds;
- receive a second artwork;
- generate a project including the first artwork and the second artwork;
- and
- generate Verifiable Credentials of the project, the Verifiable Credentials including a first electronic signature generated by encrypting an identifier of a Decentralized Identity document of the project by a private key of the artist of the first artwork,
- wherein authentication of the user who selects the first artwork is considered to have succeeded when the first electronic signature is able to be decrypted by a public key of the user, and the authenticating is considered to have failed when the first electronic signature is not able to be decrypted by the public key of the user.
