A COMPUTER-IMPLEMENTED METHOD OF ISSUING CERTIFICATES

Resumen de: WO2024246585A1

This invention relates to a method 20, 30 of issuing and verifying certificates. The method includes receiving 21, at an NFT assigner 14, a request from an issuer 12 to issue an NFT associated with a certificate. The NFT assigner then validates 22, using a validation module 14.2, the request using cryptographic techniques, ensuring that the request is authentic and authorized. Once the request is validated, the NFT assigner 14 generates 23, using an NFT generator 14.1, a unique and non-interchangeable NFT associated with the certificate. The NFT is then stored or recorded 24 on the blockchain network 16, providing an immutable and transparent record of ownership and authenticity. The NFT assigner 14 then issues 26 the generated NFT to the issuer 12 through the API, providing a standardized and secure way to retrieve the NFT and verify authenticity of the certificate thus preventing fraudulent falsification of degree certificates.
