Secure Content Distribution with Self-Destructing Compressed Files
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current content distribution technologies fail to secure sensitive information from exposure once it is shared with a receiver, as there is no mechanism to ensure the information remains confidential beyond the receiver's control.
Innovation Solution
A system that determines the recipient's status (internal or external) and applies customized security measures, including a cyclic redundancy check (CRC) code and self-destruction mechanism, to ensure sensitive information is accessed only by authorized parties and deleted after a retention time, thereby preventing exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If confidential information is shared with a receiver using password protection, then the information can be accessed by the receiver, but the information remains permanently exposed on the receiver's device unless manually removed
Solution Approach 1:
The patent applies preliminary action by embedding a self-destruction mechanism within the compressed file that automatically deletes the confidential information after a predetermined retention period expires. This pre-programmed action ensures the information is automatically removed from the receiver's device without requiring manual intervention, thereby resolving the contradiction between ease of access and exposure risk.
Solution Approach 2:
The patent treats the confidential information as a temporary, disposable object by implementing an automatic deletion mechanism that destroys the file after a set retention period. This approach allows the information to be temporarily accessible for its intended purpose while ensuring it does not persist indefinitely on the receiver's device, thus eliminating long-term exposure risks.
2Duration of action of moving object
If manual removal of confidential information is required, then the information can be kept accessible, but the system complexity increases and user burden increases
Solution Approach 1:
The patent applies self-service by programming the compressed file with automatic self-destruction capabilities. The file independently manages its own lifecycle by automatically deleting itself after the retention period expires, without requiring user intervention or complex external security management systems. This resolves the contradiction by providing controlled retention duration while minimizing system complexity.
Solution Approach 2:
The self-destruction mechanism is pre-programmed into the file during creation, establishing the retention duration in advance. This preliminary configuration eliminates the need for ongoing manual management or complex security systems, as the file autonomously executes its deletion after the predetermined time period.
3Ease of operation
If confidential information is stored indefinitely on receiver's device, then the information remains accessible, but security risk and storage space consumption increase
Solution Approach 1:
The patent implements a temporary, disposable approach to information storage by automatically deleting the confidential file after a predetermined retention period. This ensures the information is accessible during the needed timeframe while automatically freeing up memory space afterward, resolving the contradiction between accessibility and storage space consumption.
Solution Approach 2:
The self-destruction mechanism enables automatic discarding of the confidential information after its useful lifetime expires. This process recovers the occupied memory space without requiring manual user action, thus resolving the contradiction between maintaining information accessibility and freeing up storage resources.

AI summary
A system is configured for managing a plurality of files containing sensitive information associated with an organization to be sent to a particular receiver. The system is further configured to determine whether the particular receiver is an internal receiver or an external receiver with respect to the organization. If the particular receiver is an external receiver, a CRC code generated from the personal information and location coordinates of an external server where the plurality of files will be accessed is added to the plurality of files. A security code is also added to the plurality of files to facilitate that they are secured from being exposed and disposed at a retention time set by the organization. The system generates a custom compressed file from the plurality of files, configures it to be decompressed by the personal information of the external receiver, and sends it to the external receiver.
