Volatile Memory Data Management for Information Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data management systems fail to effectively prevent information leakage when using hibernation or dump functions, as data stored in auxiliary storage devices can be retrieved, leading to potential user data exposure upon loss or disposal of the electronic computing machine.
Innovation Solution
An electronic data management system that utilizes volatile memory as a pseudo auxiliary storage, encrypting user data and storing it in network storage, ensuring it is not left on local devices, and implementing authentication and deletion mechanisms to secure data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If data is stored in auxiliary storage devices (hard disk, USB memory) for convenient access and usage, then ease of operation is improved, but information leakage risk increases when the device is lost or disposed of
Solution Approach 1:
The patent extracts the data storage function from the auxiliary storage device and relocates it to network storage. The electronic computing machine no longer retains user data locally, but accesses and processes it remotely through network connection, thereby eliminating the leakage risk while maintaining operational convenience.
Solution Approach 2:
The patent introduces network storage as an intermediary between the user and the data. Instead of direct storage on local auxiliary devices, data is stored on remote network storage, which acts as a mediator that provides data access functionality while preventing local data retention and potential leakage.
2Reliability
If data is stored in network storage to prevent local leakage, then information security is improved, but device complexity increases due to network dependency
Solution Approach 1:
The patent makes the electronic computing machine multi-functional by enabling it to access various types of storage (local and network) through a unified interface. The system can operate with network storage as the primary storage, eliminating the need for complex local storage management while maintaining data accessibility.
3Object-affected harmful factors
If volatile memory is used as pseudo auxiliary storage for data-less usage, then information leakage is prevented, but data accessibility and reliability deteriorate due to volatility
Solution Approach 1:
The patent extracts the data persistence function from volatile memory and relocates it to network storage. Volatile memory is used only for temporary data processing, while all user data is stored remotely, combining the security benefits of volatility with the reliability of persistent network storage.
Solution Approach 2:
The patent performs preliminary data retrieval from network storage before processing. Data is fetched in advance to volatile memory for processing operations, ensuring that no sensitive data remains stored locally after processing completes, thereby preventing leakage while maintaining processing efficiency.

AI summary
The present disclosure prevents the leakage of user data by preserving user data working not in an electronic computing machine. A part of a storage area of a main memory of a user terminal is used as a RAM disk. User data working is encrypted and stored in the RAM disk. The user data stored in the RAM disk is sent to a network storage, the RAM disk and the network storage are synchronized. Since the user data is controlled by using a driverware technology inside the electronic computing machine, and sent to the network, therefore the security is ensured.
