Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital verifiable credential systems face compatibility issues due to different formats and standards, making it difficult for users to present and verify credentials across various environments.
Innovation Solution
A Verifiable Credential Exchange (VCE) system and method that enables the automatic conversion of digital verifiable credentials from one format to another, allowing holders to present and verify credentials across different operating environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different VC formats and standards are supported, then credential compatibility across environments is improved, but system complexity increases
Solution Approach 1:
The patent introduces a credential exchange service as an intermediary between credential holders and verifiers. This service automatically converts credentials from source formats to target formats using format conversion logic, eliminating the need for verifiers to directly support multiple credential formats. The exchange service acts as a mediator that handles format compatibility, thereby improving credential compatibility while keeping the verifier system simple.
Solution Approach 2:
The credential exchange service provides universal functionality by supporting multiple source formats and multiple target formats through a single service interface. Rather than requiring separate conversion mechanisms for each format pair, the service universally handles any format conversion request by selecting appropriate conversion logic, thereby achieving broad compatibility without proportionally increasing system complexity.
2Ease of operation
If automatic format conversion is implemented, then user convenience is improved, but processing time increases
Solution Approach 1:
The system performs preliminary actions by pre-establishing format conversion logic and credential exchange pathways before actual credential verification is needed. The exchange service is pre-configured with knowledge of multiple formats and conversion rules, so when a credential needs to be exchanged, the conversion process can proceed efficiently without ad-hoc analysis or manual intervention.
3Reliability
If comprehensive credential verification across all formats is performed, then verification reliability is improved, but computational resources increase
Solution Approach 1:
The patent extracts the format conversion and verification complexity from the verifier and concentrates it in the credential exchange service. The verifier only needs to verify credentials in its native format, while the exchange service handles all format conversion and cross-format verification logic. This extraction allows verifiers to maintain high reliability without consuming excessive computational resources for format handling.
Data Source
AI summary
A non-transitory computer readable storage medium has instructions executed by a processor to host a digital verified credential exchange in network communication with different verified credential operating environments. The digital verified credential exchange has a verified credential exchange engine in network communication with user and system interfaces for interacting with a verified credential holder machine, a credential database, a verified credential operating environment operating attributes database, an exchanged verified credential database, and an exchanged verified credential status monitor. The digital verified credential exchange automatically forms a reissued digital verified credential from a first verified credential operating environment for execution in a second verified credential operating environment.
