SIM-Based User Authorization Verification for Secure Content Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current messaging systems, including conventional and convergent messaging systems, lack automatic user verification, particularly age verification, which is essential for protecting minors from harmful content.
Innovation Solution
A method and system that automatically trigger user authorization checks by querying a verification authority, such as the SIM or USIM, and requiring additional authentication through a personal identification number (PIN) or biometric data, ensuring high reliability and security by preventing user manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automatic user verification is implemented in communication services, then user authorization reliability is improved, but device complexity increases
Solution Approach 1:
The patent introduces a verification authority as an intermediary component that mediates between the communication service and the user's terminal device. This verification authority automatically checks user authorization by querying the SIM/USIM card and coordinating with authentication mechanisms, thereby improving authorization reliability while keeping the complexity distributed across multiple components rather than concentrated in one device
Solution Approach 2:
The verification system is segmented into multiple independent components: the verification authority, the SIM/USIM card storage, the terminal device interface, and the communication service. This segmentation allows each component to perform its specific function with simplified logic, reducing the complexity burden on any single device while collectively achieving high reliability
2Reliability
If SIM/USIM querying is used for verification, then manipulation resistance is improved, but ease of operation deteriorates
Solution Approach 1:
The SIM/USIM card automatically provides verification data when queried by the verification authority through the terminal device. The user does not need to manually input or manage this data - the system self-services by leveraging the already-present SIM/USIM card that the user possesses, thus maintaining ease of operation while ensuring manipulation resistance through the secure embedded storage
3Reliability
If additional user authentication is required, then security is improved, but productivity deteriorates
Solution Approach 1:
The system performs preliminary verification by automatically querying the SIM/USIM card for user authorization data before requiring additional authentication. This preliminary action filters out unauthorized users early in the process, so that only legitimate users need to proceed to the additional authentication step, thereby minimizing the productivity impact while maintaining high security
Solution Approach 2:
The authentication process is made dynamic by adapting the verification steps based on the outcome of the preliminary SIM/USIM check. Authorized users experience a streamlined process with faster access, while unauthorized users are blocked early. This dynamic adjustment optimizes productivity for legitimate users while maintaining security through the multi-layered approach
