Virtual Credential Visual Verification via Contextual Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual credential systems often disseminate unnecessary information and lack effective methods for authentic verification, as recipients may receive more information than needed, and visual inspection is insufficient to establish authenticity due to the ease of image copying and modification.
Innovation Solution
The system determines contextual data to modify visual characteristics of displayed credential information, allowing selective disclosure of credential data based on the relying party's role, location, and privacy settings, using NFC tags and cryptographic methods for authentication and verification through a cloud-based infrastructure.

Engineering Contradiction Analysis
1Loss of information
If all credential data is displayed on the virtual ID card, then the relying party receives complete information for verification, but unnecessary information is disseminated that the license holder does not want to share
Solution Approach 1:
The credential data is segmented into multiple fields (e.g., name, address, license number, expiration date) that can be independently controlled. The system allows selective disclosure by enabling the license holder to choose which specific fields to display on the virtual ID card, thus providing complete information when needed while preventing unnecessary information dissemination in other contexts.
Solution Approach 2:
The virtual ID card system implements dynamic control over information display based on contextual factors. The license holder can dynamically adjust which credential fields are visible depending on the situation, relying party identity, or verification purpose, transforming a static all-or-nothing disclosure model into a flexible, context-aware information release mechanism.
2Ease of operation
If visual inspection is used to verify credentials, then the verification process is simple and quick, but authenticity cannot be reliably established due to ease of image copying and modification
Solution Approach 1:
The system introduces an intermediary verification mechanism that bridges visual inspection and cryptographic validation. A verifying application acts as a mediator between the displayed credential and the verification authority, enabling users to visually verify credentials while simultaneously performing cryptographic authentication through intermediate verification steps that confirm the credential's authenticity without requiring complex manual procedures.
Solution Approach 2:
The system replaces manual mechanical verification methods (visual inspection of physical features) with cryptographic verification mechanisms. Instead of relying on humans to visually detect security features, the system uses digital signatures, hash functions, and cryptographic protocols to automatically verify authenticity, substituting mechanical human judgment with automated cryptographic validation that is both simple to operate and highly reliable.

AI summary
Providing virtualized credentials of a license holder includes determining contextual data that governs visual information presented on a display and displaying credential data on the display, where visual characteristics of the credential data that is displayed varies according to the contextual data. The display may be a display on a device of the license holder or a display on a device that is viewable by a relying party. The visual characteristics may be modified according to a location of at least some of the credential data on the display on the device of the license holder, a particular font used, a particular color used for text, a color scheme of an existing image and/or a specific image that is independent of the credential data. The visual characteristics may be modified according to the color scheme by changing a background color on the screen of the device of the license holder.
