Remote Terminal Data Deletion via Permission Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing mobile terminals do not allow for the remote deletion of all information, leaving security risks when the device is lost or stolen, as they only delete data from secure digital memory cards and not other private data.
Innovation Solution
A method and apparatus for remotely deleting all information from a terminal, which involves acquiring permission for remote deletion, receiving a deletion command from a server, and performing the deletion based on verification of user and terminal information, ensuring all data is cleared, including non-SD card storage data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only SD card data is deleted remotely, then the existing anti-unloading protection function is maintained, but other private data such as mailbox data, call records and WeChat records cannot be deleted, resulting in security risks
Solution Approach 1:
The remote deletion system is enhanced to perform multiple deletion functions across different data storage locations. The deletion command now covers not only SD card data but also private data stored in the terminal's internal memory, including mailbox data, call records, and messaging application data, making the security protection universal across all data types
2Reliability
If all information deletion permission is acquired and complete data deletion is performed, then comprehensive data security is achieved, but the system complexity and verification requirements increase
Solution Approach 1:
The terminal pre-acquires deletion permissions for all data types and stores them locally before a deletion command is received. When a remote deletion command arrives, the terminal simply verifies the command against the pre-stored permissions and executes the deletion without needing complex real-time verification, thus reducing system complexity while maintaining comprehensive security
Solution Approach 2:
A permission verification mechanism acts as an intermediary between the remote deletion command and the actual data deletion process. The system verifies account information and terminal information carried in the command against stored credentials, providing a structured intermediate verification layer that manages complexity while enabling comprehensive deletion

AI summary
The present application relates to the field of communications. A method and apparatus for remotely deleting information are provided. In some embodiments, the method includes: when a user logs in to a terminal and requests enabling a remote deletion function, acquiring a permission for deleting all information; receiving an all information deletion command sent by a server after the user performs remote login; and performing, according to the command and the permission, an operation of deleting all information in the terminal. In some embodiments, the apparatus includes an acquiring module, a reception module, and a deletion module.
