There have been countless high-profile hacks and personal information leaks. Furthermore users don’t (and shouldn’t) always trust an external server of a third party to store their personal data. Blockchain tries to offer a compelling solution to the problem of combining accessibility with privacy and security. Records can be held securely, using end-to-end encryption, and yet openly authenticated so that data can still be trusted as reliable. This project goes deeper in this solution thanks to an innovative idea and development of a new kind of blockchain non fungible token specifically created to store and manage digital identities and sensible data. It has the potential to resolve issues blockchain alone was starting to approach and improves security, privacy and accessibility.enBlockchain non fungible tokenblockchaindigital identityidtokensecurityprivacyidchainhyperledger indyText/Conference Paper10.18420/ois2020_151617-5468
