Instant Messaging Auto-Deletion via Embedded Command
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication technologies lack the ability for automatic deletion of instant messaging information after transmission, leading to potential privacy leaks if the receiver fails to manually delete the information in time.
Innovation Solution
Incorporating an automatic deletion command set by the user into the transmitted information, which is detected and executed by the receiving terminal, allowing for immediate or timed deletion of the information after it is received and displayed, with optional user agreement before deletion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual deletion by receiver is used, then information can be deleted from receiving terminal, but receiver may forget to delete information in time leading to privacy leaks
Solution Approach 1:
The system enables self-service deletion by embedding an automatic deletion command in the transmitted information that executes automatically at the receiving terminal without requiring manual user action. The receiving terminal autonomously deletes the information after playback based on the embedded command, eliminating the need for users to manually remember and perform deletion operations.
2Extent of automation
If automatic deletion command is embedded in information, then information can be deleted automatically after playback, but system complexity increases
Solution Approach 1:
The automatic deletion command is merged directly into the information content during the transmission process. The transmitting terminal embeds the deletion command within the same data stream as the information itself, so that a single transmission packet contains both the information and the deletion instruction, eliminating the need for separate control messages or complex protocol handshakes.
Solution Approach 2:
The information packet itself serves as an intermediary carrier that transports both the content and the deletion command from the transmitting terminal to the receiving terminal. This intermediary approach allows the deletion instruction to be delivered passively along with the information without requiring additional communication channels or complex coordination mechanisms.
3Reliability
If automatic deletion is implemented, then privacy protection is improved, but user control over information retention is reduced
Solution Approach 1:
The system provides dynamic control by allowing the transmitting user to configure different deletion timing options when embedding the deletion command. Users can select whether deletion should occur immediately after playback, after a specified time delay, or under other conditional triggers, enabling flexible adaptation to different privacy needs and scenarios.
Solution Approach 2:
The deletion command and timing parameters are predetermined and embedded in the information before transmission. This preliminary configuration allows users to establish their privacy preferences in advance, and the system automatically executes the predetermined deletion action without requiring real-time user intervention, balancing automation with user control.

AI summary
The present invention discloses a method for automatically deleting instant messaging information. The method includes receiving, by an information transmission terminal, an automatic deletion command from a user of a transmitter, carrying the command in information to be transmitted, transmitting the information; and receiving and playing or displaying, by an information receiving terminal, the information, determining whether the information carries the automatic deletion command, if the information carries the automatic deletion command, deleting the information automatically. In the present invention, the information is deleted automatically according to a command of the user of the information transmission terminal after the information receiving terminal receives and plays the information.
