Mobile Device Partition Access via Single SIM Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication devices do not allow users to have multiple profiles or partitions on a single device, making it difficult to separate different aspects of life without needing multiple devices, and existing solutions require separate SIM cards or user IDs for each partition.
Innovation Solution
A method and system that enables a user to access and switch between partitions on a mobile device using a single identification module, such as a SIM card, by verifying a partition-specific code and identification data, allowing secure access to predefined content and functionality without the need for multiple SIM cards or user IDs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple SIM cards or user IDs are used for each partition, then security and user separation are improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The system divides the mobile device into multiple partitions (work profile, personal profile, guest profile) that can be independently accessed. Each partition has its own dedicated storage space and can be selectively activated, allowing security to be maintained for each partition while managing complexity through structured organization rather than multiple physical SIM cards.
Solution Approach 2:
A single SIM card is made multi-functional by enabling it to access multiple partitions through different authentication mechanisms. The SIM card serves as a universal access point that can switch between work profile, personal profile, and guest profile based on authentication credentials, eliminating the need for separate SIM cards for each function.
2Reliability
If multiple SIM cards are used for each partition, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The system dynamically switches between different partitions based on authentication credentials. When a user presents different authentication information (different PUK codes, passwords, or biometric data), the system dynamically activates the corresponding partition, providing secure access to different profiles without requiring physical SIM card changes.
Solution Approach 2:
The system introduces an intermediary authentication layer that mediates between the SIM card and partitions. Instead of directly linking each partition to a separate SIM card, the authentication mechanism acts as an intermediary that verifies credentials and grants access to appropriate partitions, simplifying the user interface while maintaining security.
3Ease of operation
If a single identification module is used for all partitions, then ease of operation is improved, but security deteriorates
Solution Approach 1:
Different security levels and authentication methods are applied to different partitions based on their specific requirements. The work profile may require enterprise-grade authentication, while the personal profile uses standard SIM authentication, and the guest profile uses simplified access. This local quality approach maintains security where needed while improving ease of operation where appropriate.
Solution Approach 2:
The system changes authentication parameters (PUK codes, passwords, biometric requirements) based on which partition is being accessed. The same SIM card can present different authentication parameters depending on the target partition, allowing a single identification module to maintain security through parameter variation rather than requiring multiple physical modules.

AI summary
A method of accessing a partition on a mobile communication device may include the steps of receiving data specifying a partition, receiving an identification code from an identification module in or associated with the device, determining, based on both the data specifying a partition and the identification code, whether access to the specified partition is to be allowed, and allowing or denying access to the specified partition accordingly.
