Problems solved by technology

[0002] At present, the business of multimedia message (also known as multimedia message, multimedia message, multimedia mail, and Caiyi) is developing rapidly, but there is a problem in content protection: the sender user or SP (Service Provider, service provider) , the control right of this multimedia message is in the receiver's hands, and the receiver can save, edit, and forward this multimedia message at will, which cannot protect the content security of the multimedia message
[0003] In addition, the multimedia message content protection method based on DRM (Digital Rights Management) technology needs to insert DRM additional information into the multimedia message content. At the same time, mobile terminals need to support the analysis and processing of DRM additional information. function, unable to achieve multimedia message content protection

Embodiment Construction

[0019] The invention adds a WAP server in the current mobile network to store protected multimedia message content. The multimedia message center (also known as the MMS center, Caiyi center) judges that the received multimedia message is a protected multimedia message according to the service prefix number, and sends the protected multimedia message content to the WAP server. The WAP server stores the protected multimedia message content and generates The WAP webpage of the protected multimedia message content, and send the URL link of the WAP webpage to the PUSH proxy gateway in the form of a PUSH message, and the PUSH proxy gateway sends the PUSH message to the receiving user. After receiving the PUSH message, the receiving user needs to Open the PUSH message, log in to the WAP server, and only view the content of the protected multimedia message after the mobile phone number is authenticated. Because the content of the protected multimedia message is stored on the WAP serve...

Abstract

The invention relates to a multimedia message content protecting technique of mobile communication network, in particular to a method for protecting multimedia message content. The invention adds a WAP server in a mobile communication network, stores and generates a WAP webpage of protected multimedia message content, sends the URL linkage of the WAP webpage via PUSH message to a PUSH proxy network gate. The invention can effectively protect the content safety of multimedia message, and holds the control priority of multimedia message content in sender or SP. Therefore, multimedia message receiver is limited to access multimedia message, without storage, edit, and transfer abilities, to protect the safety of multimedia message content. And the invention is not based on DRM function of mobile phone, with better compatibility.

Description

technical field [0001] The invention relates to a technology for protecting multimedia message content in a mobile communication network, in particular to a method for realizing protection of multimedia message content, especially realizing restricted access to multimedia message content at a receiver. Background technique [0002] At present, the business of multimedia message (also known as multimedia message, multimedia message, multimedia mail, and Caiyi) is developing rapidly, but there is a problem in content protection: the sender user or SP (Service Provider, service provider) , the control right of this multimedia message is in the hands of the recipient, and the recipient can save, edit, and forward this multimedia message arbitrarily, which cannot protect the content security of the multimedia message. [0003] In addition, the multimedia message content protection method based on DRM (Digital Rights Management) technology needs to insert DRM additional informatio...
