Message Protection via Segmented Transmission and Request-Based Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing message services expose sensitive information of message senders or recipients when users access messages in public places, and users are hesitant to store such information in message servers due to security concerns.
Innovation Solution
A method for protecting messages involves acquiring a protection message, configuring message data for transmission by excluding at least a portion of the text, and transmitting this data to a receiving terminal. The receiving terminal can request the text, and upon approval, the text is transmitted and processed for exposure to the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the message text is transmitted to the receiving terminal, then the user can access the message content, but sensitive information is exposed to others in public places
Solution Approach 1:
The patent applies preliminary action by pre-configuring message data in a protected state before transmission. The message text is excluded from the transmitted data structure in advance, and only metadata is sent. The full text is made available only after the receiving terminal requests it, preventing premature exposure in public places while maintaining eventual accessibility.
Solution Approach 2:
The patent extracts the message text from the transmitted data by sending only metadata initially. The text component is separated and withheld, being transmitted only upon explicit request from the receiving terminal. This extraction approach minimizes exposure risk during initial transmission while preserving access capability when needed.
2Reliability
If the message text is excluded from transmission, then sensitive information is protected, but the receiving terminal cannot display the message content
Solution Approach 1:
The patent applies dynamics by making the message text transmission conditional and dynamic rather than static. The text is excluded from initial transmission but can be dynamically added and transmitted to the receiving terminal upon request. This dynamic approach ensures security during initial transmission while enabling content availability when the receiving terminal needs it.
3Object-affected harmful factors
If the message text is transmitted only upon request, then information exposure risk is reduced, but additional communication steps are required
Solution Approach 1:
The patent applies segmentation by dividing message transmission into two distinct segments: metadata transmission and text transmission. The message data structure is segmented so that metadata is sent initially while text is withheld and transmitted separately upon request. This segmentation reduces information exposure risk by ensuring only essential metadata is transmitted initially, with text added only when needed.

AI summary
There is provided a method for protecting a message, performed by a transmitting terminal. The method may comprise acquiring a protection message; configuring message data for transmission by excluding at least a portion of a text of the protection message; transmitting the message data to a receiving terminal of the protection message; receiving a text request for the protection message from the receiving terminal; and transmitting the text of the protection message to the receiving terminal in response to the text request.
