Function Set Access Control for Electronic Device Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face security vulnerabilities as they allow unrestricted access to all functions based on user identification, compromising overall security.
Innovation Solution
Implementing a system where the processor acquires registered identification information, sets specific function sets based on this information, and grants access only to the permitted functions, thereby enhancing security by limiting user access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electronic device allows user access to all functions based on identification information, then the ease of operation is improved, but the security is worsened
Solution Approach 1:
The patent segments function access rights by dividing all device functions into multiple function sets, each associated with specific identification information. Instead of allowing universal access to all functions, the system segments access control at the function level, enabling users to access only the functions corresponding to their authenticated identification information.
Solution Approach 2:
The patent applies local quality by assigning different access permissions to different function sets based on the authenticated identification information. Each function set has specific access control characteristics tailored to the user's identity, allowing fine-grained control over which functions are available to which users rather than uniform access across all functions.
2Reliability
If the electronic device uses identification information to determine user access, then the security is improved, but the device complexity is worsened
Solution Approach 1:
The patent implements preliminary action by pre-establishing multiple function sets and their corresponding identification information before actual access occurs. The system prepares and stores the mapping between identification information and function sets in advance, allowing rapid authentication and function selection during actual user access without requiring complex real-time decision-making.
Solution Approach 2:
The patent introduces an intermediary mechanism that mediates between the user authentication process and function access. This intermediary component handles the matching between identification information and function sets, simplifying the overall system architecture by centralizing the access control logic in a dedicated module rather than distributing it throughout the entire system.
