Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing identity verification systems on mobile devices face challenges in integrating biological recognition and Near-field communication (NFC) to ensure user data privacy and compatibility across various application scenarios.
Innovation Solution
A mobile device and verification terminal device system that captures biological characteristics, generates a token with access information including a public information status, and transmits it to a server, which then verifies the identity by modularizing the verification process, allowing applications to interface with the identity verification system without bearing the cost of identity verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biological recognition and NFC are integrated into mobile devices for identity verification, then verification accuracy and security are improved, but device complexity and data privacy risks increase
Solution Approach 1:
The patent introduces a server as an intermediary component that receives biological characteristic data from the mobile device, generates the verification token, and returns it to the mobile device. This mediator approach reduces the complexity burden on the mobile device itself, as the computationally intensive token generation and verification logic is offloaded to the server, while the mobile device only needs to handle data collection and communication.
2Reliability
If all access information is included in the token, then verification completeness is improved, but user data privacy is compromised
Solution Approach 1:
The patent applies local quality by differentiating the privacy protection level for different types of information within the token. The token structure includes both public information (device identifiers, verification status) that can be openly shared, and private information (biological characteristics, personal data) that is protected and only accessible under specific conditions. This selective information disclosure maintains verification completeness while protecting user privacy.
Solution Approach 2:
The patent changes the parameter of information disclosure by introducing a public information status indicator in the token. This parameter dynamically controls what level of information is exposed - the token can indicate whether certain fields contain public or sensitive data, allowing the system to adapt the disclosure level based on verification requirements and privacy policies.
3Ease of operation
If applications perform their own identity verification, then verification control is improved, but development cost and operational burden increase
Solution Approach 1:
The patent extracts the identity verification function from individual applications and consolidates it into a separate, dedicated identity verification system. Applications no longer need to implement their own verification logic - they simply integrate with the standardized token system. This extraction reduces development costs and operational burden for each application while maintaining verification control through the centralized system.
Solution Approach 2:
The patent creates a universal identity verification token that can be used across multiple different applications and scenarios. A single token generated by the mobile device can serve various verification purposes (access control, authentication, authorization) without requiring separate verification systems for each application. This multi-functionality reduces overall system complexity and development costs.
Data Source
AI summary
A mobile device includes a biological information detecting device and a wireless communication interface. The mobile device uploads the biological characteristic to the server. The server generates a token that corresponds to the biological characteristic and transmits the token to the mobile device. The mobile device transmits the token to the verification terminal device. The verification terminal device can confirm the identity of the user by verifying the token. This modularizes the process of identity verification, replacing the verification process of applications that need to verify identity, so that these applications do not need to bear the cost of identity verification after interfacing with the identity verification system.
