Data Card Hidden Partition for Information Concealment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for protecting data information on data cards, such as those used in notebook computers, have low security levels, making user private information vulnerable to attackers, as encryption methods are not effective in preventing data access.
Innovation Solution
A method and apparatus that select and store sensitive information in a hidden partition of the data card, using predetermined conditions like short messages with specific content to authenticate users and activate a hidden function, thereby increasing security by concealing the information's existence from attackers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If information is stored directly in the computer, then accessibility is improved, but security deteriorates because computer viruses are rampant
Solution Approach 1:
The patent extracts sensitive information from the computer's main storage system and relocates it to a hidden partition within the data card. This physical separation ensures that even if the computer is compromised by viruses or attackers, the sensitive information remains isolated and protected in the data card's secure storage environment.
Solution Approach 2:
The patent implements a nested structure where a hidden partition is created within the data card's storage system. The hidden partition contains sensitive information and is accessible only through specific authentication mechanisms, while the outer layer presents a normal storage interface to the user. This nested architecture provides multiple layers of protection.
2Reliability
If encryption methods are used to protect information, then security is improved, but attackers can still acquire the information easily
Solution Approach 1:
The patent introduces a hidden partition as an intermediary layer between the user and the sensitive information. This hidden partition acts as a mediator that requires specific authentication (such as predetermined short messages) to access, adding an intermediate security checkpoint that prevents direct access even if encryption is compromised.
Solution Approach 2:
The patent implements preliminary authentication mechanisms by setting predetermined conditions (such as specific short message content) that must be satisfied before the hidden partition becomes accessible. This preliminary action prevents unauthorized access before any data retrieval attempt occurs.
3Reliability
If a hidden partition is created in the data card, then security is improved by concealing information existence, but device complexity increases
Solution Approach 1:
The patent makes the data card multi-functional by enabling it to operate in both normal mode (for general storage and communication) and hidden mode (for secure information storage). The same physical data card performs multiple functions depending on the authentication state, eliminating the need for separate hardware solutions and reducing overall system complexity.
