Embodiment Construction

[0039]The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0040] In order to realize the compressed transmission of the digital rights object, the core idea of ​​the present invention is: in the ROAP rights object response (ROResponse) message, compress the copyright information (rights) of Extensible Markup Language (XML, Extensible MarkupLanguage) format according to the agreed algorithm , to reduce the data volume of ROResponse data during transmission; after receiving the ROResponse message, the terminal decompresses the compressed data according to the agreed algorithm to restore the real ROResponse message.

[0041] Based on the above-mentioned core idea, the present invention provides a transmission method for compressing copyright, such as figure 1 As shown, the method mainly includes the following steps:

[0042] In step 101, the terminal negotiates with the server...

Abstract

The invention discloses a transmission method for compressing copyright, which includes: a terminal negotiates a compression algorithm with a server; in a copyright object request message, the terminal requests the server to transmit copyright information in a compressed format through an extension field; the server generates a copyright object response in a standard manner message, compress the copyright information in the copyright object response message according to the negotiated compression algorithm, and generate a compressed copyright object response message and send it to the terminal; the terminal receives the compressed copyright object response message, and compresses the received message according to the negotiated compression algorithm The copyright information in the rights object response message is decompressed, and the decompressed rights object response message is generated. The invention also discloses a transmission system for compressing copyright, which reduces the data volume of ROAP communication and improves the reliability and user experience of digital copyright object transmission.

Description

technical field [0001] The invention relates to digital copyright management technology in mobile communication, in particular to a transmission method and system for compressing copyright. Background technique [0002] Digital rights management technologies are designed to deliver and consume digital rights content in a manageable manner to ensure that intellectual property is consistently protected throughout the value chain. The content format (DCF, DRM Content Format) of digital rights management (DRM, Digital Right Management) is usually encrypted, and users can obtain it through various channels such as downloading from the Internet, receiving multimedia messages, emails, or sharing from other users. In order to use the digital content normally, the user also needs to purchase a digital rights object (RO, Right Object), and use the digital content under the regulations and restrictions of the digital rights. Digital content can only be used when RO is obtained, so in ...
