Apparatus and methods for non-fungible tokens as universal digital identification

This invention describes a system where a unique digital token, called an NFT, is given to a person to serve as their universal digital ID. When the person needs to prove who they are online, they temporarily send this NFT to a special computer program, which checks the token's history to confirm their identity. Once confirmed, the token is sent back to them, ready for future use, and if it gets stuck, it's automatically returned after five minutes.

Why it matters: Filed during early NFT hype, the underlying distributed ledger and smart contract infrastructure for identity solutions has matured significantly since 2021. This makes building robust, secure systems for managing digital identity with NFTs more feasible and reliable, especially concerning the specified timeout mechanisms.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedSoftware logic, distributed ledger, smart contracts, cryptography.
