Electronic Device Token Generation for Unified Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices require both identity verification and information proving ownership for users to access or use objects, leading to inconvenience and longer queues, as users need to prepare and present separate verification methods.
Innovation Solution
An electronic device that irreversibly generates a token based on biometric information and ownership information, combining these into encryption information with assistance information to facilitate secure and convenient access, allowing users to authenticate with a single token.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users present both identity verification and ownership information separately, then authentication security is maintained, but user convenience deteriorates and processing time increases
Solution Approach 1:
The patent combines identity verification and ownership verification into a single token that integrates both authentication functions. The token is generated by irreversibly combining biometric information (identity) with ownership information, allowing users to present one unified credential instead of multiple separate verifications, thereby improving convenience and reducing authentication time
Solution Approach 2:
The token serves multiple authentication functions simultaneously - it acts as both an identity credential and an ownership proof. This multi-functional design eliminates the need for separate identity verification and ownership verification processes, resolving the contradiction between maintaining security and improving user convenience
2Reliability
If multiple verification methods are required, then authentication reliability is improved, but device complexity increases
Solution Approach 1:
The system merges multiple verification functions (identity check and ownership check) into a single token generation and verification process. The processor generates one token that encapsulates both verification requirements, and the verification process checks this single token for both identity and ownership validity, thereby maintaining authentication reliability while reducing system complexity
Solution Approach 2:
The token acts as an intermediary that carries both identity and ownership information in a unified format. Instead of requiring the system to handle multiple separate verification streams, the token mediates the authentication process by providing all necessary verification data in one package, simplifying the overall system architecture

AI summary
An electronic device is provided. The electronic device includes an input/output interface and at least one processor configured to irreversibly generate a first token to use or access an object based on first biometric information input through the input/output interface and information proving ownership of the object, and output the first token through the input/output interface.
