Description

Method and system for preventing multimedia message forwarding

The present invention relates to a multimedia message information protection technology in the field of mobile communications, and in particular, to a method and system for preventing multimedia message forwarding. Background technique

With the development of communication technology, the application of communication tools such as terminals is changing with each passing day, which is dizzying. While enriching people's lives, it also satisfies the individual needs of different people. The extension and development of common functions such as SMS and MMS are gradually enriched. For example, the use of MMS for identity identification, or MMS e-vouchers has gradually gained favor from end users and e-vouchers. In the prior art, the method for using the MMS for identity identification may be: using a two-dimensional barcode as an identity code of the terminal, where the identity identification code is stored in the terminal in the form of a multimedia message; when identifying the identity of the terminal, When the two-dimensional barcode MMS on the terminal is compared with the two-dimensional barcode on the authentication server to determine that the two match, the mobile terminal passes the identity verification.

Although the above MMS application technology is simple to implement, due to the immature technology, the MMS application cannot be widely promoted. The reason is: If the MMS identity code applied by the end user is forwarded, it can be used by many people. The uniqueness of the identification code cannot be guaranteed; in addition, if the electronic coupon issued by the merchant is widely forwarded, the economic interests of the merchant will be infringed; if the patented MMS has been forwarded, the infringement will be involved. Therefore, if the above problems caused by the MMS being forwarded are not resolved, the promotion and application of MMS will be hindered.

In the prior art, some high-end terminals have their own intellectual property protection information, so that such terminals cannot forward MMS messages with MIDI, SISx, JAR and other format attachments, but the method for preventing MMS from being forwarded is too inflexible. What MMS information should be protected cannot be determined by the end user. Therefore, this method does not play a good role in preventing MMS from being forwarded, and the end user experience is poor. Summary of the invention

In view of this, the main purpose of the present invention is to provide a method and system for preventing and forwarding multimedia messages, which can effectively prevent the MMS provided by the MMS provider from being forwarded and protect the interests of the MMS provider.

FIG. 2 is a schematic structural diagram of a system for preventing and forwarding a multimedia message according to the present invention. detailed description

The basic idea of the present invention is: Before the MMS providing terminal sends the MMS, the anti-forward flag is set for the MMS; during the MMS sending process, the MMS service center determines the MMS type received, and if the received MMS only carries the anti-forwarding The flag bit sets a forbidden forwarding flag for the MMS, and then sends the MMS with the forbidden forwarding flag to the MMS receiving terminal; if the received MMS carries the forbidden forwarding flag, the MMS is refused to be sent.

In the present invention, the anti-forward flag is set by the MMS providing terminal; the forbidden forwarding flag is set by the MMS service center, and any terminal cannot set and modify the forbidden forwarding flag of the MMS; the MMS provides the terminal and the MMS The receiving terminal can parse the anti-forward flag bit and the forbidden forwarding flag bit, that is, the MMS providing terminal and the MMS receiving terminal are both terminals that support the anti-forward function.

The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

FIG. 1 is a schematic flowchart of a method for implementing anti-forwarding of a multimedia message according to the present invention. As shown in FIG. 1, the implementation steps of the process are as follows:

Step 101: Before the MMS providing terminal sends the MMS, the anti-forward flag is set for the MMS; specifically: the MMS providing terminal sets the anti-forward flag for the MMS to be sent by the MMS receiving terminal, that is, the anti-forward flag is true. The value, that is, the MMS to be sent is set to the anti-forward MMS, and then the MMS carrying the anti-forward flag is sent to the MMS service center.

Step 102: During the process of sending the multimedia message, the MMS service center determines the type of the MMS received, such as If the received multimedia message only carries the anti-forward flag, step 103 is performed; if the received multimedia message carries the forbidden forwarding flag, step 104 is performed;

Specifically, in the process of sending a multimedia message, the MMS service center determines the type of the MMS to be sent after receiving the MMS to be sent by the MMS sending terminal, and if the MMS to be sent carries only the anti-forward flag, that is, the MMS to be sent is Step 103 is performed to prevent the forwarding of the MMS message. If the MUST message is carried in the MMS to be sent, step 104 is performed.

The MMS sending terminal may be a MMS providing terminal, or may not be a MMS providing terminal. If the MMS sending terminal is a MMS providing terminal, the MMS sent by the corresponding MMS sending terminal carries the anti-forward flag bit; if the MMS sending terminal It is not a MMS providing terminal, which may be the first receiving terminal of the MMS, and the MMS sent by the corresponding MMS sending terminal will carry the forbidden forwarding flag. The reason is: The forbidden forwarding flag described in the present invention is only used by the MMS service center. Setting, any terminal can not set and modify the forbidden forwarding flag of MMS. For the setting method of the forbidden forwarding flag, see step 103.

Here, if the to-be-sent MMS does not carry the anti-forward flag bit or the forbidden forwarding flag bit, the MMS to be forwarded is processed according to the sending process of the existing ordinary MMS, that is, the MMS is directly sent to the MMS receiving terminal.

Step 103: Set a forbidden forwarding flag for the MMS carrying the anti-forward flag, and then send the MMS with the forbidden forwarding flag to the MMS receiving terminal;

Specifically, the MMS service center sets a forbidden forwarding flag for the MMS carrying the anti-forward flag, that is, the forbidden forwarding flag of the MMS is true, and then the MMS with the forbidden forwarding flag is sent to the MMS receiving terminal, and then Go to step 105.

In the present invention, the MMS sent to the receiving terminal carries the anti-forward flag bit in addition to the forbidden forwarding flag bit, that is, the anti-forward flag bit of the MMS message sent by the original MMS providing terminal is a true value, and the forwarding flag is forbidden. The value of the bit is false; after the MMS service center is set, in addition to the MMS anti-forward flag is true, the MMS's forbidden forwarding flag is also true. Step 104: Refusing to send a multimedia message carrying a forbidden forwarding flag;

Specifically, the MMS service center refuses to send the MMS message carrying the forbidden forwarding flag, and then notifies the sending terminal that prohibits the forwarding of the MMS message, and performs step 105. Of course, the transmitting terminal forbidding the forwarding of the multimedia message is not a multimedia message providing terminal.

It can be seen that even if the MMS message containing the forbidden forwarding flag is sent out, it will eventually be recognized and intercepted by the MMS service center, making the forwarding failure.

Step 105: The MMS anti-forwarding process ends.

According to the present invention, after receiving the MMS message carrying the forbidden forwarding flag sent by the MMS service center, the MMS receiving terminal may first parse the forbidden forwarding flag bit in the MMS message to determine that the forbidden forwarding flag bit is true, then The MMS is set to read-only MMS, that is, the MMS cannot be saved as, cannot be edited, and cannot be forwarded. In actual application, these corresponding options of the MMS can be made unavailable, and displayed as a gray button. In this way, the MMS receiving terminal can only read the MMS but cannot perform operations such as forwarding, and further achieve the purpose of preventing the MMS from being forwarded.

Here, if it is determined that the forbidden forwarding flag bit in the multimedia message is a true value, the multimedia message is set as a read-only multimedia message; the MMS receiving terminal has a function of parsing the forbidden forwarding flag bit, if the MMS receiving terminal does not have the resolution of the forbidden forwarding flag bit If the function is received, the receiving terminal cannot read the multimedia message even if it receives the multimedia message, or the read multimedia message is garbled.

The invention is described in detail below with reference to specific embodiments.

In this embodiment, the process of applying the identity MMS or the MMS e-voucher to the service providing terminal to issue the identity MMS or the MCU e-voucher is described as an example. The MMS application terminal is described in the present invention. The MMS receiving terminal, the specific process is as follows:

The MMS application terminal sends the service application information to the service providing terminal via the MMS service center; after receiving the application information, the service providing terminal sets the MMS or the MCU of the MMS application terminal to the anti-forward MMS and sends it to the MMS service center. The MMS service center sends the MMS to the MMS application terminal's identity MMS or the MMS e-voucher. After applying for the terminal, the MMS application terminal can only read the MMS content but cannot forward it to other terminals after receiving the MMS or the MMS e-voucher. The MMS or the MMS e-voucher is only used by the MMS application terminal.

2 is a schematic structural diagram of a system for preventing and forwarding a multimedia message according to the present invention. As shown in FIG. 2, the system includes: a multimedia message providing terminal and a multimedia message service center;

The MMS providing terminal is configured to set an anti-forward flag bit for the MMS before sending the MMS message; the MMS service center is used to determine the type of the MMS message received during the MMS sending process, and determine that only the received MMS message is carried. When the anti-forward flag is set, the forbidden forwarding flag is set for the MMS, and then the MMS carrying the forbidden forwarding flag is sent to the MMS receiving terminal; when it is determined that the received MMS carries the forbidden forwarding flag, the MMS is refused to be sent.

The system further includes: a multimedia message receiving terminal, configured to receive a multimedia message sent by the multimedia message service center.
