Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional encryption technologies for secure information exchange in social networking services are complex, inconvenient for users, and increase security risks due to the need for server-side integration and key issuance, often resulting in unauthorized disclosure of personal and confidential information.
Innovation Solution
An encryption method utilizing a hardware logic circuit to generate and manage user features, creating a hardware function for access authentication in social networking services, which ensures secure data transmission and decryption only by matching hardware logic circuits, reducing the need for user intervention and central server dependency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional encryption technologies are used for secure information exchange, then data security is improved, but system complexity and operational inconvenience increase
Solution Approach 1:
The patent extracts the encryption function from the server-side system and relocates it to a standalone encryption accessory with hardware logic circuit. This separation removes the complex key management and encryption operations from the main SNS system, reducing overall system complexity while maintaining security.
Solution Approach 2:
The encryption accessory performs encryption and decryption operations autonomously using its internal hardware logic circuit and stored user features. The accessory serves itself by generating encryption keys locally and performing cryptographic operations without requiring server-side key issuance or management, simplifying the overall system.
2Reliability
If server-side encryption key issuance is implemented, then data security is improved, but user operational convenience deteriorates
Solution Approach 1:
The encryption accessory autonomously generates encryption keys and performs cryptographic operations using its hardware logic circuit and stored user features. Users simply need to provide biometric authentication, and the accessory handles all encryption/decryption operations automatically, greatly improving operational convenience.
Solution Approach 2:
The encryption accessory acts as an intermediary device between the user and the SNS system. It mediates the authentication process by verifying user features locally and performing encryption/decryption operations, eliminating the need for users to directly interact with complex server-side key management systems.
3Reliability
If conventional encryption systems are deployed, then information security is improved, but security risks increase due to complex key management
Solution Approach 1:
The patent extracts the key management function from the server system and places it in the encryption accessory's hardware logic circuit. This separation isolates the sensitive key management operations from the networked SNS system, reducing the attack surface and potential security risks while maintaining strong encryption.
Solution Approach 2:
The encryption accessory uses volatile memory for storing encryption keys and temporary data, ensuring that sensitive information is automatically erased when power is removed. This approach reduces the risk of key leakage through persistent storage while maintaining security during operation.
