Embodiment Construction

[0034] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0035] Such as figure 1 Shown is a schematic structural diagram of a mobile terminal according to an embodiment of the present invention, and the mobile terminal 10 includes:

[0036] The processing module 11 is configured to encrypt the short message to be sent, generate an encrypted short message, and create encryption key information corresponding to the encrypted short message.

[0037] The first sending module 12 is configured to send the encrypted short message and the encryption key information to a server.

[0038] The storage module 13 is used for storing related information of the sent encrypted short message.

[0039] The related information of the sent encrypted short message includes: ID (Identifier, identifier) ​​of the encrypted short message, content of the encrypted short message, phone...

Abstract

The invention provides a mobile terminal for withdrawing the short message, a server, a system and a method for the same. The mobile terminal comprises: a processing module for performing encryption treatment for the short message to be sent, to generate an encrypted short message, and establishing an encrypted key message corresponding to the encrypted short message; a first sending module for sending the encrypted short message and the encrypted key message to a server; a storing module for storing information associated with the sent encrypted short message; a withdrawing module for generating information for withdrawing the encrypted short message according to the information associated with the sent encrypted short message; a second sending module for sending the information of the withdrawn encrypted short message to the server. The invention cancels the encrypted key information corresponding to the encrypted short message stored on the server, so that the receiver part cannot check the encrypted short message; therefore, the invention implements the purpose of withdrawing the short message.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a mobile terminal, server, system and method for withdrawing short messages. Background technique [0002] The current mobile terminals basically support the function of sending and receiving short messages. Short messages have the characteristics of fast sending and receiving and low cost. Therefore, short messages have become an indispensable communication method in modern people's lives. [0003] Yet people often run into the situation of misoperation when sending short message, for example, the receiver of input is wrong or the short message content of input is wrong, when above-mentioned misoperation takes place, people hope to withdraw the short message that has sent, let the recipient party cannot view to avoid unnecessary misunderstanding. [0004] The method of withdrawing short message in the prior art is: define CANCEL_SM (short message cancellation) command in the...
