Verifiable Credential Usage Tracking via Data Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack a mechanism to track the usage of verifiable credentials, especially when they are presented using multiple devices, making it difficult to monitor and manage their usage effectively.
Innovation Solution
A data structure that represents verifiable credentials along with usage data, allowing users to monitor and track how their credentials are used, including frequency of exposure, last exposure details, and device information, and provides visual and machine-readable representations for easy interpretation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If verifiable credentials are made portable and presentable on multiple devices, then user convenience and accessibility are improved, but tracking and monitoring usage becomes more difficult
Solution Approach 1:
The patent implements a feedback mechanism where usage data from verifiable credential presentations is collected and fed back to the user through a user interface. This allows users to monitor usage frequency, exposure details, and device information, resolving the tracking difficulty while maintaining portability across multiple devices.
Solution Approach 2:
The patent introduces an intermediary system that acts as a mediator between the verifiable credential presentations and the user. This intermediary collects usage data, processes it, and presents it in a comprehensible format, enabling users to track usage without directly managing the complexity of multi-device tracking themselves.
2Loss of information
If usage data is collected and stored for verifiable credentials, then usage tracking capability is improved, but data management complexity increases
Solution Approach 1:
The patent implements self-service where the system automatically collects, stores, and manages usage data without requiring manual intervention. The usage data is automatically updated and maintained, allowing users to access comprehensive tracking information without burdening them with data management complexity.
Solution Approach 2:
The patent creates copies of usage data in structured formats that can be easily stored and retrieved. By maintaining organized copies of usage information including frequency, exposure details, and device information, the system enables comprehensive tracking while simplifying data management through standardized data structures.
Data Source
AI summary
The presentation of a verifiable credential that is represented within a data structure that represents the verifiable credential as well as usage data of the verifiable credential. The usage of the verifiable credential is monitored, such that as usage of the verifiable credential changes or progresses, the stored usage data also changes. This data structure may be used to not only cause visual representations of the verifiable credential to be displayed to the user, but the user can selectively cause at least some of that usage data to also be presented to the user. Thus, the user can easily keep track of how their verifiable credential is being used, regardless of where or from which device the verifiable credential is presented.
