Definitions
- the invention relates to a method for disseminating DRM (digital rights management) occupied digital content. It preferably refers to the dissemination of appropriate content, especially media content, over the Internet, but without being limited thereto.
- DRM digital rights management
- a so-called token he acquires, usually by download from a rights control server, a so-called DRM server of a distributor, a license in the form of a key and associated rights attributes, which govern the type, extent and / or duration of permissible use of the content.
- the key is connected to the device-specific hardware and / or software of the respective device to which it is transferred.
- the use of the respective content is firmly tied to the appropriate device.
- the object of the invention is therefore to provide a solution which, despite the use of DRM, allows a more flexible use of correspondingly secured digital contents.
- the object is achieved by a method having the features of the main claim.
- Advantageous embodiments or further developments of the invention are given by the subclaims.
- the proposed method is for the distribution of digital content, which are occupied by DRM, wherein the content, as known in the art, is encrypted and its playback is bound to a license.
- the license is designed as a digital key and linked to attributes, so-called rights, which govern the type, scope and / or duration of permissible use of the content.
- a digital ticket (hereinafter DRM ticket) is made available to the acquirer of licenses for a content secured by DRM, which represents a unique, addressable via a computer network target address on a server (hereinafter also DRM server).
- DRM server a server
- a user who is in possession of the ticket and does not necessarily have to be the acquirer of the corresponding content may download licenses to a device used to play the content.
- licenses are generated at the moment of their request made using the DRM Ticket based on rights coupled to the DRM Ticket, the respective rights being determined by the Content Provider as the DRM Ticket is created.
- the ticket production which preferably by using a Random number in conjunction with a hashing algorithm takes place on the DRM server itself or the ticket is generated on a system of the content provider and transmitted to the DRM server, that is, the corresponding destination address is set up there and connected to the DRM server.
- Ticket coupled rights transmitted in the form of corresponding attributes.
- a license generated as such later using the DRM ticket is in turn delivered as a device-specific license with associated keys for decrypting the content occupied by DRM, ie transmitted to a device suitable for playing the content.
- the acquirer is initially provided with the licenses only indirectly as a digital ticket, namely as an unidentifiable address referring to an address on a server, namely the DRM server.
- licenses can later be obtained using the DRM ticket as a device-specific license.
- an additional instance is thus virtually realized, by means of which the licenses, with regard to the receivers or the devices used by them, can be assigned more flexibly, so that the content can be distributed more flexibly and indeed also independent of the actually underlying DRM system of a user assigning rights.
- DRM ticket corresponding address
- the acquirer may give the relatives or friends the use of the content by giving them the DRM ticket they have purchased with the associated rights and thus the licenses to be generated at the address specified by the ticket.
- the respective rights are determined by the distributor of the licenses when creating the DRM ticket.
- the destination address designated by a DRM ticket according to the invention is preferably the URL of an Internet page held on a DRM server which can be contacted via the Internet.
- the content provider for administration and billing purposes in the course of the generation of the DRM ticket, with the rights linked thereto for the use of the respective digital content, by the content provider a content ID and a usage ID and optionally a shop ID to the destination address of the DRM server designated by the DRM ticket.
- the DRM ticket may be embodied as a text file storable on a device of the acquirer and / or a user of the content, or as a URL which is bookmarked by the source providing the digital ticket directly into a browser executable on the device.
- one or more digital tickets entitling to use DRM content are managed in a ticket box.
- This is embodied in the form of a database which is held on a server that can be contacted via a computer network, with a user of the DRM ticket authenticating himself to using it in relation to the ticket box.
- said server is the DRM server itself.
- the user then needs to store, for example in his browser for all digital content to be played back using the method, only one address or URL under which all DRM tickets are managed for him wherein the user, after selecting a ticket for its use, is redirected to the address indicated by the DRM ticket.
- the presented method realizes a level above the hitherto independent and generally proprietary DRM systems of different providers and operators. It is possible that the destination addresses used to perform the method on the DRM server represent DRM tickets of different content providers for generating licenses of one or more licensors.
- the distribution of DRM tickets according to the invention is preferably via online shops, with an acquired DRM tickets via the Internet to the Purchaser is issued.
- the ticket is transferred in the course of a download on a device of the acquirer or in the aforementioned ticket box.
- DRM tickets via removable storage media.
- the DRM tickets are then managed in a device of the purchaser or a user in their possession on the respective removable storage medium or transferred to the memory of the device for management of the removable storage medium.
- the use of the ticket box is also conceivable for this distribution channel.
- the DRM ticket (s) will be replaced by the corresponding one
- an encrypted URL is attached to the content occupied by DRM which, in the event that licenses for authorizing the content are not available on a user's terminal intended for the reproduction of the content, is contacted automatically by this terminal , Under this URL, the user of the terminal has the option of purchasing a DRM ticket menu-driven or accessing a DRM ticket managed in a ticket box.
- the DRM tickets have a limited validity period. This is useful, for example, in order to avoid that tickets that have not been used over a longer period of time may have to be kept in the form of an ever-increasing number of URLs on the DRM server, but possibly also to prevent manipulation attempts. It is also conceivable to set a maximum number of licenses that can be generated for the purpose of downloading a DRM ticket.
- Fig. 1 The processes in the use of a DRM ticket in the form of a
- FIG. 2 The procedures for acquiring a DRM ticket in a representation corresponding to FIG. 1
- Fig. 1 shows the procedures for using a DRM ticket. Thereafter, the process of using a corresponding ticket is as follows.
- the user starts on a suitable device, for example an MP3 player, a content occupied by DRM, for example an encrypted music title.
- the hardware and software of the player will be used to verify that the device has a license to play the selected digital content. If this is the case, the content, ie according to the selected example of the music titles, can be reproduced in accordance with the specifications of the license present on the device or according to the rights given by the license.
- a URL encrypted in the content is read out and establishes a connection to a server via the Internet using this URL.
- the connection establishment and the menu-driven communication with the server are carried out by means of a browser supported by the player.
- the server is the DRM server itself or a server via which, depending on the selection made by the user via the menu, the DRM server is contacted.
- the software for the menu-driven communication as in the illustrated example, also held on the DRM server, that is, from the aforementioned player immediately a URL on the DRM server is contacted.
- the user can make a menu-driven decision whether to purchase a DRM ticket or to use a previously purchased ticket managed in a ticket box. Any and all acquired from or owned by him or by a third party then located DRM ticket he then, as in the example, directly or via a link to another server of the content provider, a generated at this moment license to play the content selected by him.
- the ticket box is, as in the example shown, preferably managed on the DRM server itself. Regardless of the number and type of tickets managed in the ticket box, ie addresses or URLs, the user only needs to know and address the address of the ticket box and can then, after authentication, have the digital tickets stored therein.
- Access to an optionally already stored on the DRM server in the ticket box digital ticket he receives, for example, as already generally known for access to the Internet, as part of a login, so an authentication procedure.
- the DRM ticket purchased by the user personally or given to him for use and possibly administered in the ticket box has a period of validity that can be specified by the content provider in connection with the tariff classification for his purchase.
- the user can download licenses for using the content from different devices via the DRM ticket, or the address represented by the ticket, in accordance with the example of an address on the DRM server.
- the licenses can be used according to the rights they contain and the conditions specified by them for the reproduction of the content.
- the content may be audio, video, or other non-media content.
- the respective license then regulates the rights granted for the use of the corresponding content, such as playback, viewing or printing. If the user tries to access a DRM ticket in the ticket box, but there is no valid ticket stored for him, he is also forwarded to a website for a ticket purchase.
- the Fig. 2 also divided into parts 2a and 2b, shows the procedures for ticket purchase.
- the ticket purchase takes place at an online shop. about a browser contacts the user the online shop.
- he selects a product for which he wants to purchase a digital or a DRM ticket.
- This is delivered to him after acquisition in the form of a unique, non-fake URL, which is generated using a random number and using a hash algorithm.
- the user can optionally store the ticket himself on a suitable terminal or have it managed in a ticket box, preferably on the DRM server. In the former case, he is responsible for managing the tickets themselves.
- the ticket box has the advantage that there the ticket is protected against accidental deletion or theft.
- a license linked to the DRM ticket is generated upon contacting the URL of the DRM server designated by the digital ticket and transmitted together with the key for decrypting a DRM-secured content to the device used for the connection to the DRM server.
- a content ID and a usage ID are transferred from the online shop to the DRM server in the course of generating the DRM ticket with the rights linked to it.
- a shop ID transmitted. The content ID is later used to deliver a license requested for a particular content using the DRM ticket to the user, which license is transmitted to the device used for the purpose of displaying corresponding content.
- the license is in turn, as known in the art, a device-specific license.
- the overlying layer of the transferable digital ticket may be used by different users on different devices, in each case device-specific licenses.
- the DRM tickets are, as in the example presented above, preferably distributed or purchased online. Of course, it is also conceivable to bring the corresponding URL via other means to the customer, such as removable storage media, such as CD or DVD. same for for the digital, occupied by DRM content whose distribution, as well known from the prior art, based on the technical means used for this purpose is basically independent of the distribution of the licenses required for its use.
- the digital content can reach the player of the user.
- Players are typically PC, laptop, PDA, MDA, MP3 players, cell phones, or similar devices with digital storage and a way to load digital content.
