Embodiment Construction

[0045] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0046] The flow of a method for restricting user operations on media objects in the present invention is as follows: image 3 shown, including the following steps:

[0047] In step s301, the sending terminal encapsulates the media object into a digital rights management message. The media object can be encapsulated into a digital rights management message in FL (Forward-lock) format or CB (Combined delivery) format according to user needs. If it is only necessary to prohibit the receiving terminal from forwarding, prohibiting editing, and prohibiting the copying of the media object, it can be encapsulated in FL format. If it is necessary to attach other restrictions to the media object, it is necessary to generate a copyright object with restriction information and share it with the media The object is encapsulated as a digital rights management messa...

Abstract

The method comprises: the sending terminal packages the media object as digital copyright management message; sending terminal sends the digital copyright management message to the receiving terminal.The invention also reveals a mobile terminal capable of limiting the users to operate media object.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for restricting user operations on media objects and a mobile terminal. Background technique [0002] With the continuous development of network communication technology, especially the digitalization of information media, users can transmit information to all parts of the world through electronic devices such as computers and mobile phones. However, while digital information is widely disseminated, higher requirements are also placed on the security of digital information. For example, the media object can be forwarded by methods such as bluetooth, infrared or MMS (Multimedia Messaging Service, multimedia multimedia message service) between mobile phones, but because the user who sends the media object cannot restrict the use of the receiving user to the received media object, the receiving user The received media object can be edited and forwarded arbitrarily, ...
