Abstract: A system capable of securely authenticating users of a web application (or similarly distributed application). This invention, WebAuthn+, along with a simple addition to the Web Bluetooth API will completely solve the web authentication problem. And most users will be able to keep the convenience of user names and simple passwords! Simple passwords will become highly secure. The fact that no one else has proposed this simple addition to the Web Bluetooth API, argues for the uniqueness of this invention. In addition to secure authentication, this invention will enable the creation of Cryptographically Secure Distributed Ledgers as a “Shared Source of Truth”. Users will be able to sign a distributed ledger with one touch of their mobile device. Additions to the distributed ledger will be considered a new block, a hash code will be created and signed by the user responsible for that step in the process.

Abstract: A “Secure Mobile Identity System” that enables the creation of secure digital credentials on mobile devices, prevents identity theft, prevents fraudulent financial transactions, protects privacy, enables a simplified federation process and provides a consumer friendly “One Click Sign On”™ process. Also, the user's credentials are secure if his/her mobile device is lost or stolen.
