Identification of multimedia message content. On the one hand, it enables the network side to filter out the identified bad media information, effectively reducing the audio-visual pollution of bad media information to users from the source; on the other hand, it can also realize the transmission control or transmission volume statistics of specific media information , to provide effective means of control and related statistical data for the copyright protection of network media information. the

Referring to FIG. 3 , another embodiment provides a method for processing a multimedia message, which implements security and adaptation processing on the content of the multimedia message while performing authentication on the content of the multimedia message. The specific steps include:

Step S301, the MMSC obtains the multimedia message to be sent. the

Step S302, the MMSC sends a first processing request to the MCPS, and the first processing request includes multimedia message content and security processing instruction information; and receives the first processing result returned by the MCPS. the

In this step S302, the first processing request is a message sent by the MMSC to the MCPS requesting that the content of the multimedia message be safely processed. The corresponding message of the first processing request can be implemented in a variety of ways, and is still given in Table 1. MCP-content-process.REQ is taken as an example, and it is indicated by assigning a value to one of the parameters X ₁ X ₂ X ₃ X ₄ contained in its processing type field (X-MCPS-process-Type) Request for secure processing of multimedia message content, for example, by assigning a value to parameter X3 to indicate the request for secure processing of multimedia message content, MMSC sends MCP-content-process.REQ to MCPS, and makes X-MCPS-process- The value of the parameter X3 in the Type field is "1", which means that the MMSC has sent the above-mentioned first processing request to the MCPS, that is, requesting the MCPS to perform security processing on the content of the multimedia message.

In the step S302, the MCPS performs security processing on the content of the multimedia message, such as disinfecting the multimedia message, and then feeds back a multimedia message security processing response to the MMSC, so as to feed back the security processing result to the MMSC. The security processing result includes: safe and dangerous. When the security processing result is safe, it means that the current multimedia message will not cause harm to the receiving terminal; when the security processing result is dangerous, it means that the current multimedia message will cause harm to the receiving terminal. the

In this step S302, the corresponding message returning the first processing result can adopt multiple implementation methods, still taking the MCP-content-process.RES given in Table 2 as an example, by processing the type field (X-MCPS- process-Type) to assign a value to one of the multiple parameters X ₁ X ₂ X ₃ X ₄ ..., indicating that the response message is the processing result returned after the multimedia message content is safely processed. For example: MCPS sends MCP-content-process.RES to MMSC, and makes the parameter X3 in the X-MCPS-process-Type field take the value "1", which means that MCPS returns the above-mentioned first processing result to MMSC, that is, sends The MMSC returns the securely processed multimedia message content.

Among them, MCPS may include Media Content Security System (Media Content Security System, hereinafter referred to as MCSS), Media Content Identification System (Media Content Identification System, hereinafter referred to as MCIS), Media Content Adaptation System (Media Content Adaptation System, hereinafter referred to as for MCAS). The MMSC sends the first processing request to the MCSS in the MCPS, and the MCSS returns the first processing result to the MMSC. the

Step S303, the MMSC sends a second processing request to the MCPS, and receives the second processing result returned by the MCPS. the

This step S303 has the following two implementations:

Implementation mode 1: MMSC sends the second processing request described in step S202 in the above-mentioned embodiment to MCPS; the same processing method as in step S203 in the above-mentioned embodiment may also be used for returning the second processing result to MMSC by MCPS. the

Implementation mode two: the second processing request sent by the MMSC to the MCPS includes not only multimedia message content and authentication processing instruction information, but also adaptation processing instruction information. Specifically include:

The MMSC sends the second processing request including the adaptation processing indication information to the MCIS in the MCPS;

After MCIS authenticates the content of the multimedia message, it initiates a content adaptation request to MCAS, and carries the authenticated multimedia message content in the content adaptation request;

MCAS performs adaptation processing on the content of the received multimedia message, and returns the adaptation processing result to MCIS;

The MCIS generates a second processing result according to the adaptation processing result, and returns it to the MMSC. the

In the second implementation above, the MMSC sends to the MCIS the corresponding message of the second processing request containing the adaptation processing indication information, which can be implemented in various ways, still taking the MCP-content-process.REQ given in Table 1 as an example , by assigning values to a plurality of parameters X ₁ X ₂ X ₃ X ₄ ...... contained in its processing type field (X-MCPS-process-Type) to indicate the request to perform identification and adaptation processing on the content of the multimedia message For example, when the parameter X1 is assigned a value of "1" to indicate that the multimedia message content is requested to be adapted, and the parameter X2 is assigned a value of "1" to indicate that the multimedia message content is requested to be authenticated, the MMSC Send MCP-content-process.REQ to MCIS, and make the parameter X1 and parameter X2 in the X-MCPS-process-Type field both take the value "1".

When the MMSC sends the second processing request by adopting the first implementation mode above, and obtains the returned second processing result, the following step S304 may also be included. the

Step S304, the MMSC sends a third processing request to the MCAS, the third processing request includes the authenticated multimedia message content and the adaptation processing instruction information, and receives the third processing result returned by the MCAS after the adaptation processing. the

In this step S304, the corresponding message of the third processing request sent by the MMSC to the MCAS can be implemented in a variety of ways, still taking the MCP-content-process.REQ given in Table 1 as an example, through its processing type field ( One of the multiple parameters X ₁ X ₂ X ₃ X ₄ contained in X-MCPS-process-Type) is assigned a value to indicate that the content of the multimedia message after authentication is requested to be adapted, for example, by The parameter X1 is assigned a value of "1" to indicate that when it is requested to adapt the content of the authenticated multimedia message, the MMSC sends MCP-content-process.REQ to the MCAS, and makes the X-MCPS-process-Type field The value of parameter X1 is "1". That is, it means that the MMSC has sent the third processing request to the MCAS, that is, requesting the MCAS to perform adaptation processing on the authenticated multimedia message content.

In this step S304, the corresponding message returning the third processing result can adopt multiple implementation methods, still taking the MCP-content-process.RES given in Table 2 as an example, by processing the type field (X-MCPS- process-Type) to assign a value to one of the multiple parameters X ₁ X ₂ X ₃ X ₄ ......, indicating that the response message is the processing result returned after the multimedia message content is adapted. For example: MCAS sends MCP-content-process.RES to MMSC, and makes the parameter X1 in the X-MCPS-process-Type field take the value "1", which means that MCAS returns the above-mentioned third processing result to MMSC, that is, to The MMSC returns the multimedia message content that has undergone authentication and adaptation processing.

205. The MMSC sends a notification request (MM1_notification.REQ) to the receiving agent according to the security processing result, so as to notify the receiving agent that a multimedia message arrives. Specifically, when the result of security processing is safe, a notification request is sent to the receiving agent to notify the receiving agent of the arrival of a multimedia message; when the result of security processing is dangerous, the multimedia message can be discarded and other processing, and the process ends. The process of sending multimedia messages next time. the

206. The receiver agent returns a notification response (MM1_notification.RES) to the MMSC, so as to return the notification result to the MMSC. the

207. The receiver agent sends a retrieval request message (MM1_retrieve.REQ) to the MMSC to retrieve the multimedia message, and the retrieval request message includes terminal attributes, so that the MCPS processes the multimedia message according to the terminal attributes, so that the processed multimedia message is suitable for the terminal. Attributes. the

208. MMSC sends a multimedia message authentication and adaptation request to MCIS (using the second implementation method), such as sending the above-mentioned MCP-content-process.REQ, so that both parameters X1 and X2 are "1", so that MCIS and The MCAS performs authentication and adaptation processing on the multimedia message, and the multimedia message authentication and adaptation request includes multimedia message content and terminal attribute information. the

209. The MCIS authenticates the multimedia message so as to effectively identify the content of the multimedia message, and then initiates a content adaptation request to the MCAS, such as sending MCP-content-process.REQ, in which the value of parameter X1 is "1". the

210. After performing adaptation processing on the multimedia message, the MCAS sends a content adaptation response to the MCIS, so as to feed back the processing result to the MCIS. the
