This invention describes a system for users to securely prove their identity and authorization for online transactions using a special digital token. When a user wants to interact with an online service, their device sends this token, which indicates they are already authenticated, to the service provider. The service provider then forwards the token to a central server, which verifies it against the user's pre-registered identity to confirm their authorization for the transaction.
Why it matters: Filed as the landscape of digital identity became increasingly fragmented and vulnerable. The growing demand for secure, user-centric, and privacy-respecting authentication solutions makes a unified token system more urgent now.
AI gives you a few directions you could take this. Pick one, and we check whether your version is different enough to patent, then write the filing.
