Definitions

  • the present invention relates to a method and a computer program product for exporting usage rights to electronic data objects.
  • CDs and other digital media can be copied differently than traditional information carriers (for example books or records) without loss of quality and without significant costs.
  • DRM Digital Rights Management
  • DRM systems realize the idea of central control of digital content through cryptographic processes. This is realized by uniquely cryptographically binding any digital content to any device and / or media. Without being provided with the corresponding key for the digital content by the rights holder, the rights purchaser can acquire the device or the data medium, but can not access the content. DRM systems are technically designed to uphold and enforce the wishes of a rightholder It is designed so that a key exchange can be made for each individual device without user intervention. This allows the rights holders new forms of distribution such as a temporary rental of content.
  • a Rights Expression Language is a formal language with which rights can be expressed.
  • OMA Open Mobile Alliance
  • Azure Microsoft
  • the problem here is to produce an interoperability between the individual DRM systems.
  • the present invention has for its object to provide a method for exporting rights of use of electronic see data objects, which ensures an interoperability between different DRM systems. According to the invention this object is achieved by a method and a computer program product having the features specified in claim 1 and claim 11. Advantageous developments of the present invention are specified in the dependent claims.
  • original usage rights of an electronic data object comprise usage forms given by a copyright holder.
  • a translation of the usage rights from a format of the data source to a format of the data sink is performed.
  • the original usage rights are exported to the electronic data object in a way that can be assigned to the data sink from the data source. This advantageously preserves the original license when exporting the usage rights from one DRM system to another DRM system, so that no rights granted by the copyright holder are irretrievably lost.
  • the original usage rights and / or the translated usage rights are identified.
  • the original usage rights are translated during the export.
  • This has in particular the advantageous effect that, for example, when an export from a first DRM system to a second DRM system and a further export from the second DRM system to a third DRM system respectively, the original license is translated and thus an availability the rights granted by the rightholder are guaranteed to the fullest extent possible.
  • the usage forms encompassed by the original usage rights are updated prior to export. This has the advantage that the rights already claimed by a rights purchaser are counted in an electronic data object and thus also the legitimate interests of the copyright holder are preserved.
  • the export is carried out by a rights purchaser and / or a rights holder.
  • the rights of use of the quel- Ie and / or data sink are not translated when the electronic data object on the data sink is not executable.
  • a bouncer function can be implemented in an advantageous manner, in which it is checked before the start of the translation process whether the usage rights assigned to an electronic data object can be executed on the respective data sink or not.
  • original rights of use of an electronic data object comprise predetermined forms of use by a copyright holder.
  • a translation of the usage rights from a format of the data source to a format of the data sink is performed.
  • the original usage rights are exported to the electronic data object in a way that can be assigned to the data sink from the data source.

  • a first DRM system 101 is installed on devices on which a second DRM system 102 is installed.
  • an electronic data object is transferred from a PC with the DRM system 1 to a PC with a DRM system 2 103.
  • This usually results in translation errors between the individual DRM systems, whereby individual rights granted by the rights holder can irretrievably be lost.
  • the electronic data object is transferred from a PC to a PDA 104 within the DRM system 2. In particular, this leads to restriction errors, since the computing power capacities of the PDA are much more limited than those of the PC.
  • a translation error also occurs during the export from the PC with the DRM system to the PC with the DRM system 2 in step 103.
  • the original license is also transferred. This original license is used for translation in the export from the PC with the DRM system 2 to the PDA with the DRM system 2 in step 104, whereby the rights of use transferred to the PDA are no longer limited by the translation error, but only be limited by the restriction error.
  • step 105 the original license is used for translation, whereby in this export of a system with small computing power capacity on a powerful system with large Computing power the rights of use can again be used in full by the right holder provided extent.
  • step 106 the electronic data object is transferred from the PC with the DRM system 2 to the PC with the DRM system 1, whereby only a translation error occurs due to the export between two different DRM systems.
  • the original license 201 provided by the copyright holder initially contains all the forms of use granted by the copyright holder to the electronic data object.
  • an exported license 203 is obtained, which only makes the usage forms granted by the right holder available to a limited extent.
  • the original license is transmitted, which is specially marked 204.
  • another export 205 for example, not the translated license 203 but the original license 204 is transmitted to the next data processing device.
  • the translation of the license in the new data processing device does not take place on the basis of the already limited exported license 203, but also on the basis of the original license 204.
  • the marking can serve to indicate to the system which license is to be used Export should be transmitted.
  • the exported license 206 is obviously much more extensive than the exported license 203, but even this type of data processing device can not use all the forms of use intended by the right holder.
  • the original license is exported, which in turn is specially marked 207. This embodiment illustrates the beneficial effect of the present invention whereby the license terms are mapped by each in the system as much as possible.

Abstract

Il existe aujourd'hui sur le marché plusieurs systèmes de gestion numérique des droits (DRM) disposant de leur propre langage d'expression des droits (REL). Le problème est que, lorsqu'un objet de données électronique est exporté d'un premier système DRM vers un second système DRM, des erreurs de traduction se produisent, de sorte que chaque droit accordé par le titulaire des droits peut être perdu de manière irrécupérable. L'objectif de l'invention est de fournir un procédé pour exporter des droits d'utilisation sur des objets de données électroniques, qui garantit une interopérabilité entre différents systèmes DRM. A cet effet, un procédé pour exporter des droits d'utilisation sur des objets de données électroniques consiste à exporter les droits d'utilisation d'origine pouvant être associés à l'objet de données électronique de la source de données vers le collecteur de données. Ainsi, lorsque les droits d'utilisation sont exportés d'un système DRM vers un autre système DRM, la licence d'origine est avantageusement conservée, de sorte qu'aucun des droits accordés par le titulaire des droits n'est perdu de manière irrécupérable.
