Unified Access Token Management for Multi-SIM Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users with communication devices equipped with multiple SIM cards or applications face the challenge of managing and synchronizing distinct PINs or access tokens, leading to complexity and increased risk of incorrect entries, which can lock applications or hinder device startup.
Innovation Solution
A method and apparatus that allow users to receive and manage user-provided access tokens by requesting information for changing access tokens between applications, accepting verification, and assigning a common verification key, thereby simplifying PIN management and reducing the need for multiple PIN entries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple distinct PINs or access tokens are managed for different applications, then security is improved, but device complexity and user operation difficulty increase
Solution Approach 1:
The patent merges multiple distinct PINs into a single unified access token that works across multiple applications. The system detects when multiple PIN-requesting applications are present and automatically generates a shared access token, eliminating the need for users to manage separate PINs for each application while maintaining security through a unified authentication mechanism.
Solution Approach 2:
The patent creates a universal access token that serves multiple applications simultaneously. This single token can be used across different applications that previously required distinct PINs, making the authentication system multi-functional and reducing the number of separate credentials users must remember and manage.
2Reliability
If multiple distinct PINs or access tokens are managed for different applications, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The patent combines multiple PIN entries into a single access token input. When a user needs to access any of the registered applications, they only need to enter one unified token instead of multiple different PINs, significantly improving ease of operation while maintaining security through the shared authentication mechanism.
Solution Approach 2:
The system automatically detects the presence of multiple PIN-requesting applications and configures the shared access token without requiring manual user setup. The automatic detection and configuration process eliminates complex manual configuration steps, making the system easy to use while maintaining strong security through automated token management.
3Ease of operation
If automatic detection and configuration of shared access token is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The system performs automatic detection and configuration of shared access tokens without requiring manual user intervention. The device autonomously identifies multiple PIN-requesting applications, generates appropriate tokens, and configures them for use, thereby improving ease of operation. The complexity is managed internally by the system rather than being exposed to the user.

AI summary
A method comprises receiving an additional user provided access token requesting application at a device already having a user provided access token requesting application. The method also comprises requesting information from a user of said device if an access token of one of said applications is to be changed to that of the other of said applications and accepting verification by one of said applications as verification of another of said applications.
