Abstract

Embodiments of the present invention provide a content screening system, a content screening apparatus and a method for content screening. The content screening apparatus includes a content screening server for receiving a message containing content to be screened, screening the content and sending a screening result. The content screening system includes the content screening apparatus and a message receiver, or includes the content screening apparatus and a content screening requester. The method for content screening includes: screening the content to be screened which are sent to the message receiver or from the content screening requester, and sending a screening result to the message receiver or content screening requester. Embodiments of the present invention provide centralized screening service for different services and thus satisfy demands of different users for content.

Claims

1. A content screening system, comprising:

a content screening requester, for sending a content screening request containing content to be screened for screening; and

a content screening apparatus, for receiving the content screening request from the content screening requester, screening the content according to the content screening request, and sending a screening result to the content screening requester;

wherein the content screening apparatus comprises a categorization entity and a content screening server;

wherein the categorization entity is configured for categorizing and/or grading the content from the content screening server or from a categorizing and/or grading requester, generating a categorizing and/or grading result, and sending the categorizing and/or grading result to the content screening server or to the categorizing and/or grading requester;

the content screening server is configured for screening the content according to the categorizing and/or grading result from the categorization entity or from the categorizing and/or grading requester, generating the screening result, and sending the screening result to the content screening requester;

wherein the content screening system further comprises a mobile terminal user database, for sending user customized screening criteria stored in mobile terminal user database to the content screening server, and storing a screening log from the content screening server;

wherein the content screening server is further configured for screening the content according to the user customized screening criteria from the mobile terminal user database in response to screening out viruses, junk and illegal information from the content, and sending the screening log to the mobile terminal user database.

3. The apparatus of claim 1, wherein the message receiving module comprises a buffer for buffering the content to be screened;

the anti-virus module comprises a virus database for storing the virus samples;

the anti-junk and anti-illegal-information module comprises a junk and illegal information database, for storing the know junk and illegal information features; and

the message transmission module comprises a buffer, for buffering the screening result to be sent.

2. A content screening apparatus for a mobile network, comprising:

a content screening server, for receiving a content screening request containing content to be screened or intercepting content to be screened, screening the content according to the content screening request and sending a screening result to an entity requesting content screening or a receiver of the content;

a categorization entity, for categorizing and/or grading the content from the content screening server or from a categorizing and/or grading requester, generating a categorizing and/or grading result and sending the categorizing and/or grading result to the content screening server or the categorizing and/or grading requester, wherein the content screening server is configured for screening the content according to the categorizing and/or grading result from the categorization entity or from the categorizing and/or grading requester and generating the screening result;

a mobile terminal user database, for sending user customized screening criteria stored in the mobile terminal user database to the content screening server, and storing a screening log from the content screening server, wherein the content screening server is further configured for screening the content according to the user customized screening criteria from the mobile terminal user database in response to screening out viruses, junk and illegal information from the content, and sending the screening log generated to the mobile terminal user database;

wherein the content screening server comprises;

a message receiving module, a management module, an anti-virus module, an anti-junk and anti-illegal-information module, a content screening module and a message transmission module;

wherein

the message receiving module is configured for parsing the content intercepted by itself or the content in the content screening request, and sending parsed content to the management module;

the management module is configured for obtaining the content from the message receiving module, instructing the anti-virus module, the anti-junk and anti-illegal-information module and the content screening module to screen the content, generating the screening result based on an anti-virus result from the anti-virus module, an anti-junk and anti-illegal-information result from the anti-junk and anti-illegal-information module and a content screening result from the content screening module, and sending the screening result generated by the management module to the message transmission module;

the anti-virus module is configured for scanning, identifying and screening out viruses in the content based on virus samples according to an instruction from the management module, and sending the anti-virus result to the management module;

the anti-junk and anti-illegal-information module is configured for screening out junk and illegal information in the content based on known junk and illegal information features according to an instruction from the management module, and sending the anti-junk and anti-illegal-information result to the management module;

the content screening module is configured for screening the content based on the categorizing and/or grading result and the user customized screening criteria according to an instruction from the management module, sending the content screening result to the management module and the screening log to the mobile terminal user database; and

the message transmission module is configured for sending the screening result from the management module to the entity requesting content screening or the receiver of the content.
