Decentralized Electronic Credential System Using Sensor Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current identity management systems rely on centralized databases, leading to fragmented user data, duplication of information, and a lack of user control over their digital identity, with trusted third parties holding significant power and potential for data misuse.
Innovation Solution
The method involves generating user-specific sensor data using electronic devices, extracting characteristic data, and creating sensed electronic credentials, which are stored as part of the user's identification information, utilizing Distributed Ledger Technology to ensure authenticity and trustworthiness without relying on central authorities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If centralized databases are used for identity management, then data storage and access are simplified, but user control and security are compromised
Solution Approach 1:
The patent segments the centralized identity management system into distributed components. Each user's identity data is divided into discrete credentials stored in a digital wallet, and the verification process is distributed across multiple parties (issuer, holder, verifier) rather than centralized in a single database. This segmentation eliminates the single point of failure while maintaining operational efficiency.
Solution Approach 2:
The patent introduces cryptographic proofs and verifiable credentials as intermediaries between users and service providers. Instead of direct access to centralized databases, users present cryptographically verified credentials that mediate the trust relationship. This intermediary layer preserves user control and security while enabling seamless data access and verification.
2Reliability
If federated instances like Facebook and Google are used for digital identity, then authorization is improved, but user control and transparency are reduced
Solution Approach 1:
The patent enables users to self-manage their digital credentials through a digital wallet application. Users have full control to select which credentials to store, when to present them, and to whom. This self-service capability empowers users with transparency and control over their personal data while maintaining the authorization benefits of federated systems through cryptographic verification.
3Reliability
If one-to-one data exchange connections are established between service providers, then data verification is improved, but system complexity and inefficiency increase
Solution Approach 1:
The patent creates a universal credential verification system where a single cryptographic proof mechanism serves multiple service providers and use cases. Instead of establishing separate one-to-one verification connections between each service provider pair, the verifiable credential standard provides a multi-functional framework that works across all participants in the ecosystem, reducing system complexity while maintaining verification reliability.

AI summary
The present disclosure relates to a system for providing an electronic credential associated with electronic identification information of a user. The system comprises one or more electronic sensor devices configured to monitor an activity or a surrounding of the user and to generate user-specific sensor data, processing circuitry configured to analyze the user-specific sensor data to extract characteristic data associated with the user, and to generate a sensed electronic credential confirming the extracted characteristic data; and a memory configured to store the sensed electronic credential as part of the user's electronic identification information.
