Abstract

The present invention discloses a method and system for realizing authorization management to digital contents, which is applied to the digital rights management technical field. The method comprises that: a file is segmented and added with index marks of segments by utilizing corresponding making tools according to different formats of the file. In an authorization license file, authorization control is performed to the segments according to business requirements. When a user uses reading / video software to perform operation, the software first examines whether the user has corresponding authority or not in the authorization license file according to the segment number of an operation object to be acquired; if the user has corresponding authority, the user is allowed to continue finishingthe operation and use the digital contents of the segment; if the user does not have corresponding authority, the present invention stops the operation to the segment and prompts the user.

Description

Method and system for implementing authorization management of digital content Technical field The invention relates to the field of digital rights management technology (digital rights management, DRM), in particular to a method and system for implementing authorization management of digital content.
