Method for safely deleting messages of instant messaging system

Abstract

The invention discloses a method for safely deleting messages of an instant messaging system. The method comprises the following steps: step 1, a first instant messaging terminal initiates a message deleting request to a communication server; after receiving the deletion request, the communication server sends the deletion request to the second instant messaging terminal and feeds back information to the first instant messaging terminal; step 2, after receiving the deletion request, the second instant messaging terminal deletes the message to be deleted; and step 3, if the second instant messaging terminal forwards the message to other instant messaging terminals, the second instant messaging terminal is used as a request initiator, and the step 1 is repeated until feedback information of all the instant messaging terminals on the message forwarding chain is obtained and summarized to the first instant messaging terminal. According to the method, even if the opposite terminal forwards the to-be-deleted message to other terminals, the message can still be withdrawn from other terminals; if the message is a file message and is downloaded by the opposite terminal or other terminals, the downloaded file can still be deleted.

Description

Technical field [0001] The present invention belongs to the field of communication, and in particular, to a message security deletion method of an instant communication system. Background technique [0002] With the development of communication technology, a large number of instant messaging terminals form a huge communication network. We have been accustomed to using instant communication terminals to communicate text, voice, pictures, etc., and the received or issued data will be forwarded and even more forwarded. In some cases, we will discover an operation error after the message or data file is issued, and the message will be revoked, and the error message can be revoked. However, when the prior art is deleted when the message received received, the user is often required to negotiate the user corresponding to the receiving end, and after the negotiation is successful, the user triggered the receiving end execution message to execute the message deletion operation, execute T...

AI Technical Summary

Problems solved by technology

However, in the prior art, when deleting a message received by the receiving end, it is often necessary for the user corresponding to the sending end to negotiate with the user corresponding to the receiving end. The process is complicated and the deletion efficiency is low; in addition, the existing technology does not support the deletion of the message to be deleted that has been forwarded to the third party by the receiver, and the misinformation message cannot be withdrawn from the third party; for the message file that has been downloaded to the local Cannot be effectively deleted, resulting in mistransferred files being retained locally at the receiving end, and there is a risk of malicious use

[0003] In view of a series of problems in the existing technology, such as low execution efficiency, inability to meet the user's need to delete messages to the greatest extent, inability to ensure the security of messages, and poor flexibility in deleting messages, this paper proposes a message security system for instant messaging systems. Delete method to meet the user's security requirements for message deletion
