Mobile Phone Body and Accessory Data Security via Wireless Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile phone security methods, such as simple encryption and anti-theft devices, are inadequate in protecting user data, as they are vulnerable to theft and lack precise reminders for stolen information.
Innovation Solution
A mobile phone system comprising a body and accessory with unique identification information, enabling secure data storage and communication, where user data is encrypted and automatically cleared if the accessory is not verified or communication is disrupted, using modules for encryption, verification, and alarm functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If user data is stored in the mobile phone, then data accessibility is improved, but data security deteriorates because the phone can be stolen or lost
Solution Approach 1:
The patent divides the mobile phone into two separate parts: a mobile phone body and a mobile phone accessory. The user data is stored in the accessory rather than the main body. This segmentation ensures that even if the phone body is stolen, the sensitive data remains secure in the accessory, resolving the contradiction between accessibility and security.
Solution Approach 2:
The patent introduces a mobile phone accessory as an intermediary component that stores user data. This accessory acts as a mediator between the user and the sensitive information, providing an additional layer of security. The accessory communicates with the phone body through wireless communication, enabling data access while maintaining security through physical separation.
2Productivity
If simple encryption algorithms are used, then processing speed is improved, but security strength deteriorates
Solution Approach 1:
The patent extracts the encryption functionality from the mobile phone body and places it in the mobile phone accessory. The accessory contains an encryption module that independently handles data encryption and decryption operations. This extraction allows the use of strong encryption algorithms without burdening the main phone processor, resolving the contradiction between processing speed and encryption strength.
3Reliability
If anti-theft devices with wireless communication are used, then theft prevention is improved, but ability to detect deliberate information theft deteriorates
Solution Approach 1:
The patent implements a verification module in the mobile phone accessory that continuously verifies the identity of the connected phone body. When the verification fails or communication is interrupted, the system provides feedback by clearing the user data. This feedback mechanism enables the detection of deliberate information theft attempts, resolving the contradiction between theft prevention and detection capability.
4Ease of operation
If user data is stored in the mobile phone body, then data access convenience is improved, but vulnerability to theft increases
Solution Approach 1:
The patent segments the mobile phone system into a phone body and an accessory, placing user data in the accessory. This physical separation maintains data access convenience through wireless communication while significantly reducing vulnerability to theft, as the accessory is smaller and can be kept separate from the main phone body.

AI summary
A mobile phone and a communication method thereof are provided. The mobile phone includes a mobile phone body and mobile phone accessory, wherein the mobile phone body includes a first communication module, a mobile phone card information reading module, a data transmission control module and a basic communication module; and the mobile phone accessory include a mobile phone card, a storage module and a second communication module. According to the mobile phone and the communication method thereof, the user data is stored in the mobile phone body and the mobile phone accessory separated from the mobile phone body; the mobile phone body and the mobile phone accessory are interconnected by wireless communication; and when the verification for the identification of the mobile phone body and the mobile phone accessory is failed or the communication therebetween is disconnected, the mobile phone body clears all the user data stored thereby automatically to prevent the user data from being stolen, therefore, the security of the user data is improved.
