Portable Storage Device IMEI Hardware Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional software security protection methods for portable memory devices are inconvenient and vulnerable to unauthorized access, as they require frequent manual code verification and can be easily decrypted.
Innovation Solution
A mobile phone accessing system and storage device implementation using a hardware method with a controller that compares International Mobile Equipment Identity (IMEI) codes to determine access permissions, ensuring only authorized mobile phones can access the storage device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If software security protection method is used, then data security is improved, but ease of operation deteriorates due to frequent manual code verification
Solution Approach 1:
The patent replaces the software-based manual code verification system with a hardware-based IMEI code verification system. The controller automatically compares the IMEI code of the connected mobile phone with the stored IMEI code in the portable memory device, eliminating the need for manual code entry and verification by the user.
Solution Approach 2:
The system performs automatic security verification through the controller comparing IMEI codes without requiring user intervention. The portable memory device autonomously determines whether to grant access based on the IMEI code match, eliminating the need for users to manually enter or verify security codes.
2Ease of operation
If software security protection method is used, then data security is improved, but reliability deteriorates as code can be easily decrypted
Solution Approach 1:
The patent replaces the software-based security code with a hardware-based IMEI code verification mechanism. The IMEI code is stored in a dedicated region of the portable memory device and automatically verified by the controller through hardware comparison, making it significantly more difficult to decrypt or bypass compared to software-based code protection.
3Reliability
If manual code verification is implemented, then security checking function is achieved, but productivity deteriorates due to frequent verification requirements
Solution Approach 1:
The patent replaces manual code verification with automatic hardware-based IMEI code comparison performed by the controller. This automated process occurs rapidly in the background without interrupting the user workflow, significantly improving data access efficiency while maintaining security protection.
Solution Approach 2:
The controller autonomously performs the security verification by automatically comparing IMEI codes when the portable memory device is connected to a mobile phone. This self-service mechanism eliminates the need for user intervention in the verification process, enabling rapid and efficient data access while maintaining robust security checks.

AI summary
The present invention provides a mobile phone accessing system. The mobile phone accessing system comprises: a mobile phone having a first International Mobile Equipment Identity (IMEI) code; and a storage device comprising a first storage region for storing data, a second storage region for storing a second IMEI code, and a controller coupled to the first storage region and the second storage region for executing a security check function to determine whether the mobile phone is qualified to access the first storage region according to the first IMEI code.
