Embodiment Construction

[0051] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0052] The method for generating a license of the present invention can generate a license when the network conditions are insufficient after the client obtains the digital media file through copying, downloading, etc., so that the client can use the encrypted digital media file.

[0053] Such as figure 2 As shown, the method for generating a license in the present invention includes the following steps:

[0054] (s1) obtaining a digital media file;

[0055] (s2) When the network is disconnected, generate an offline payment request for the obtained digital media file and apply for a license;

[0056] (s3) Generate a license for the digital media file according to the offline payment request.

[0057]By using the method described in the present invention, after the client obtains the digital media file, even if there is a network interrupti...

Abstract

The present invention discloses a method and a system for generating licenses. In the case of a network failure, clients can use the obtained digital media files normally. The method includes the following procedures: Digital media files are obtained. When a network failure occurs, an off-line payment request is generated and a license is applied for the obtained digital media file, and a licensefor the digital media file is generated based upon the off-line payment request. The system consists of a client license applying unit and a client license generating and storing unit. In the method and the system, a client license generating and storing unit is arranged at the client-side, so in the event that the client-side fails to gain access to the network, the client off-line payment record is recorded and a license is generated, thereby enabling the client-side to use the obtained digital media file normally.

Description

technical field [0001] The invention relates to the field of digital copyright protection, in particular to a method and system for generating a license. Background technique [0002] Digital Rights Management (DRM, Digital Rights Management) is a copyright protection technology for digital content, which provides an effective control method for content providers to protect their private data from illegal copying and use, so that it can effectively Prevent illegal copying, copying, and transmission of digital content through network and computer means. [0003] The principle of DRM technology is to use technical means to control and release digital media files in all aspects of distribution, transmission and use, so that digital media files can only be used by authorized people. The specific implementation of digital rights management is: the issuer of the digital media file content encrypts the digital media file and uploads it to the network. If the client wants to use th...
