The confidentiality of personal information associated with NFTs can be guaranteed through various technical measures, including encryption, hashing, and public-key cryptography.
Encryption involves scrambling the data in such a way that only authorized individuals with the decryption key can unscramble it and view the original data. This can be used to encrypt personal information stored on the blockchain associated with the NFT.
Hashing involves taking a unique fingerprint of the data, which is a fixed-length string of characters that can be used to verify the integrity of the data without revealing the original data itself. This can be used, for example, to verify the ownership of an NFT without revealing the personal information associated with it.
Public-key cryptography involves the use of a pair of keys – a public key and a private key – to encrypt and decrypt data. The public key can be safely shared, while the private key is kept secret and used to decrypt the data. This can be used to authenticate users and ensure that only authorized individuals can access the personal information associated with the NFT.
Overall, these technical measures can help ensure that personal information associated with NFTs is kept confidential and only accessible to authorized individuals.
