Problems solved by technology

[0013] Additionally, since tracking of a given content item (i.e., all copies of a given content item in AD) may be lost (e.g., due to an unconnected or powered-off device), there is no overview or easy way to determine whether the content item is still available. How many (countable) permissions are left, i.e. how many more times are allowed to play
This makes it difficult for users to know when to purchase additional playback rights, etc.

Embodiment Construction

[0034] Figure 1 schematically illustrates how devices, users, content items and licenses can be bundled into an Authorized Domain (AD). Shown is an Authorized Domain (AD) (100) with a number of devices (102) D1, D2, D3, ... DM (M equal to or greater than 1) and a number of people / users (103) P1, P2, P3, ...PN (where N is equal to or greater than 1) is bound to this AD. One or more digital licenses (L 1 ,... L L ), wherein these licenses stipulate that a given person (and / or a given group of people and / or all persons bound to the domain (100)) has , ... Which permissions are related to CL (where L is equal to or greater than 1). As noted above, such a license may be stated or undeclared. Alternatively, a license may be associated with several content items. The license may, for example, specify the right to play the movie (in the domain) 5 times, and thus be associated with all content items in the domain that are movies.

[0035] It should be noted that in practice the c...

Abstract

A device and a corresponding method for handling digital licenses, each digital license being associated with one or more content items, said device comprising a processing unit adapted to: check whether a number of licenses, being associated with a single content item or copies thereof, are designated as a stray license, where the number of licenses are present on at least one device of a group of devices, and merge the license(s) designated as stray licenses into a merged single license if the number of stray licenses is larger than 1.

Description

technical field [0001] The present invention relates to a method of handling digital licenses. The invention relates to a device for handling digital licenses. Furthermore, the invention relates to a computer-readable medium having stored thereon instructions causing one or more processing units to perform a method according to the invention. Background technique [0002] Recent developments in content distribution technologies (ie, the Internet and removable media) have made it easier than ever to exchange content. The rapid adoption by users shows that such technology really solves their needs. Content providers want to protect the copyright of content / content items that enter digital circulation. Therefore, the number of content protection systems has rapidly increased in recent years. [0003] The goal of an Authorized Domain (AD) is to find a solution that serves both the interests of content owners (who want to protect their copyrights) and the interests of content...
