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associated with the sent encrypted short message; a second sending module for sending the information of the withdrawn encrypted short message to the server.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
The present invention relates to moving communicating field, relate in particular to a kind of portable terminal, server, system and method that is used for short message withdraw.
Background technology
Present portable terminal is all supported the function that short message sends and receives basically, and short message has characteristics such as transmitting-receiving is quick, rate are cheap, therefore, becomes indispensable communication mode in modern's life.
Yet people tend to run into the situation of misoperation when sending short message, for example, the recipient's mistake of input or the content of short message mistake of input, when above-mentioned misoperation took place, people wished to recall the short message that has sent, the recipient can't be checked, in order to avoid cause unnecessary misunderstanding.
The method of short message withdraw is in the prior art: define CANCEL_SM (short message cancellation) order in short message protocol, when transmit leg finds that short message sends mistake, can send the CANCEL_SM order to server, after server is received this order, relevant information according to the short message that carries in the order, this short message of inquiry storage is not forwarded to the recipient if this short message is current, then deletes.
In realizing process of the present invention, the inventor finds that there are the following problems at least in the prior art: when network delay very little, when short message servers had been transmitted to the recipient with this short message, when promptly the recipient had received this short message, the CANCEL_SM order had also just lost meaning.
Summary of the invention
In view of this, the embodiment of the invention provides a kind of portable terminal, server, system and method that is used for short message withdraw, by cancelling the encryption key message of the encryption short message correspondence of storing on the server, make the recipient can't check this encryption short message, reach the purpose of short message withdraw with this.

Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.
Be illustrated in figure 1 as the structural representation of the portable terminal of the embodiment of the invention, described portable terminal 10 comprises:
Processing module 11 is used for the short message that needs send is carried out encryption, generates and encrypts short message, and create the encryption key message of described encryption short message correspondence.
The relevant information of the described encryption short message that has sent comprises: encrypt the ID (Identifier, identifier) of short message, the content of encrypting short message, recipient's telephone number or the transmitting time of encrypting short message.
When sending SMS message, at first the short message that will need to send by processing module 11 carries out encryption, and the corresponding encryption key message of establishment, and will encrypt short message and encryption key message sends to server end simultaneously, in the short message mistake of finding to send, in the time of need recalling this short message, then can generate the information of encrypting short message of recalling by the above-mentioned module 14 of recalling, with the encryption key message of preserving on the cancellation server, make the recipient can't download this encryption key message, thereby can't check this encryption short message, certainly, the prerequisite of above-mentioned short message withdraw is: the recipient does not also download this encryption key message this moment.
Whether in addition, successfully recall in order to understand the short message that need recall, to take other remedial measures when recalling failing, above-mentioned portable terminal 10 can also comprise:
Receiver module is used to receive the notice whether short message that described server sends is successfully recalled.
The portable terminal 10 of foregoing description all is the transmit legs as short message, certainly, is understandable that it can be used as the recipient of short message equally, and as the recipient of short message the time, described portable terminal 10 also comprises:
Above-mentioned processing module 11 can adopt multiple encryption technology that the described short message that needs to send is carried out encryption.Preferably, adopt DRM (DigitalRights Management, the digital copyright management) technology of present extensive use that the short message that needs send is carried out encryption in the embodiment of the invention.
The basic principle of DRM technology is: digital contents is encrypted, and provide copyright information to the content mandate, described copyright information comprises encryption key and corresponding added limitations information, only obtains this copyright information and could check digital contents.
In the embodiment of the invention, processing module 11 can utilize the DRM technology that the short message that needs send is carried out encryption, generate and encrypt short message, and create the copyright information comprise encryption key, and send to server by the copyright information that first sending module 12 will be encrypted short message and described encryption short message correspondence; The recipient need check when encrypting short message, just must arrive and download this copyright information on the server, to be decrypted processing to encrypting short message; When needs are recalled described encryption short message, recall module 14 and generate the information of recalling the encryption short message, to cancel described copyright information according to the relevant information of this encryptions short message of memory module 13 storages; Therefore, if the recipient is before downloading described copyright information, described copyright information is cancelled, then can't watch this enciphered message, thereby reaches the purpose of recalling short message.
In addition; the method that the short message that above-mentioned employing DRM technology sends needs carries out encryption; except the purpose of the short message withdraw that can realize the embodiment of the invention; also have the following advantages: transmit leg can be by definition in the added limitations information of copyright information to the protection intensity of the short message of transmission; for example; can be provided with and only allow the recipient to browse this short message; can not transmit or operation such as editor; the valid expiration date of copyright information perhaps is set; after surpassing this valid expiration date, the recipient then can't check.
Described copyright information can be the file of XML (Extensible Markup Language, XML (extensible Markup Language)) or WBXML (Wap Binary XML, WAP (wireless application protocol) binary system XML (extensible Markup Language)) form.
The portable terminal that provides by the foregoing description, can be when needs be recalled the encryption short message, the encryption key message cancellation of this encryption short message correspondence on the server will be kept at, make the recipient can't download this encryption key message, thereby can't check this encryption short message, reach the purpose of short message withdraw.
Be illustrated in figure 2 as the structural representation of the server of the embodiment of the invention, described server 20 comprises:
Preserve module 22, be used to preserve the encryption key message of the described encryption short message correspondence that receives.
