Identity Cryptographic Chip Biometric Key Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing identity authentication technologies in decentralized systems, such as blockchain and IoT networks, face challenges in securely managing cryptographic keys and ensuring that cryptographic operations are performed based on the true identity of a user, as private keys can be copied or lost, leading to security vulnerabilities.
Innovation Solution
The implementation of an identity cryptographic chip (ICC) that receives biometric information to verify user identity and authorize cryptographic operations, ensuring that only authorized users can perform operations by storing and managing cryptographic keys securely within the chip, using a combination of memory and logic computing components for secure storage and execution of cryptographic operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If private keys are stored as data strings on computing devices, then cryptographic operations can be performed, but security is compromised as keys can be copied or lost
Solution Approach 1:
The patent introduces a biometric authentication intermediary between the user and the cryptographic key. The biometric data (fingerprint, face recognition, etc.) serves as a mediator that verifies user identity before allowing access to or use of the private key, preventing unauthorized copying or access while maintaining ease of operation through intuitive biometric verification
2Reliability
If biometric authentication is implemented for cryptographic operations, then security is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal biometric authentication mechanism that can handle multiple types of biometric data (fingerprint, face recognition, iris scanning) through a single integrated system. This multi-functional approach improves identity verification security while avoiding the complexity of implementing separate authentication systems for each biometric type
3Reliability
If cryptographic keys are stored securely in isolated memory, then security is enhanced, but operational efficiency decreases
Solution Approach 1:
The patent performs preliminary biometric authentication and key selection before cryptographic operations are needed. The system pre-loads necessary cryptographic keys into the secure isolated memory after verifying user identity, so that when cryptographic operations are required, the keys are already in position and ready for use, eliminating delays and maintaining operational efficiency

AI summary
Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for securely performing cryptographic operations. One of the methods includes receiving biometric information associated with a user and a request to perform one or more cryptographic operations based on one or more cryptographic keys stored in a memory of an identity cryptographic chip (ICC); comparing the biometric information associated with the user with biometric information pre-stored in the memory of the ICC as pre-stored biometric information; and in response to determining that the biometric information matches the pre-stored biometric information, authorizing the one or more cryptographic operations to be performed.
