SYSTEMS AND METHODS FOR DIGITAL IDENTIFICATION AND AUTHENTICATION USING COUNTERSIGNATURE VERIFICATION

Application US20260081917A1 Kind: A1 Mar 19, 2026

Abstract

Systems and methods for digital identification and authentication using countersignature verification are disclosed. The systems and methods enable real-time identity verification between parties by associating a unique digital identification (ID) with a user's identifier, such as an email address. Upon a request for verification, the authenticating user utilizes a countersignature application to perform biometric or multi-factor authentication, triggering the generation of a one-time-use verification code. This code is communicated to a requesting user, who inputs it into the application to confirm the authenticating user's identity via a trusted server. The server validates the code against the digital ID and, upon a successful match, transmits identifying information associated with the digital ID. The systems and methods enhance security and user convenience across various interaction scenarios, including customer support, phishing prevention, and secure business communications.
