Wireless Message Redaction and Recovery System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of wireless communication devices face challenges in protecting private or sensitive information within messages, as deleting such messages permanently removes them from the device, preventing future retrieval.
Innovation Solution
A wireless communication device is equipped with a processing system that allows users to redact sensitive portions of messages, storing the redacted content while displaying the message without the redacted part, and enables recovery of the original message upon user authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the user deletes a message to protect private information, then the privacy of the message is improved, but the ability to retrieve the message later is lost
Solution Approach 1:
The patent extracts the sensitive portion of the message and separates it from the displayable content. The redacted portion is stored separately in a protected manner, allowing the non-sensitive parts to be displayed while the sensitive parts remain hidden but retrievable through authentication.
Solution Approach 2:
The message is segmented into redacted portions and non-redacted portions. The redacted portions are stored in a protected format that requires authentication to access, while non-redacted portions can be freely displayed and retrieved, thus protecting privacy while maintaining retrieval capability.
2Object-affected harmful factors
If the user redacts a portion of the message to protect sensitive information, then the privacy of sensitive information is improved, but the completeness of the displayed message deteriorates
Solution Approach 1:
Different portions of the message have different quality attributes. Redacted portions are stored with high protection (requiring authentication) while non-redacted portions are stored with lower protection (allowing free access). This local differentiation of access rights protects sensitive information while maintaining message completeness for authorized users.
3Adaptability or versatility
If the system stores both redacted and original message portions, then the flexibility of message management is improved, but the device complexity increases
Solution Approach 1:
The message storage system is designed to handle multiple types of content (redacted portions, non-redacted portions, authentication data) within a unified framework. The same storage mechanisms and processing logic are used across different message types, reducing overall system complexity despite the increased functionality.

AI summary
A wireless communication device comprises a user interface, a memory, a wireless communication interface, and a processing system. The wireless communication interface is configured to wirelessly receive a message. The processing system is configured to direct the memory to store the message. The processing system is configured to drive the user interface to display the message, display a message redaction indicator, and responsively receive a message redaction instruction. The processing system is configured to redact a portion of the message responsive to the message redaction instruction and direct the memory to store the redacted portion of the message. The processing system is configured to drive the user interface to display the message without the redacted portion, display a message recovery indicator, and responsively receive a message recovery instruction. The processing system is configured to recover the message responsive to the message recovery instruction and drive the user interface to display the message with the previously redacted portion.
