摘要： Techniques enable seamless movement and consumption of licensed digital content amongst multiple devices. In some embodiments, these techniques allow establishment of a domain capable of having multiple member devices. Each member device of the domain typically comprises a content-consuming device such as a personal computer, a portable media player, or the like. These techniques enable a license associated with digital content to bind to a domain rather than an individual device. As such, each member device of the domain may contain a domain identity and, with the identity, may consume the content with use of the license and in accordance with policy described in the license. These tools may also enable a member device to join multiple domains and to contain an identification of each of these multiple domains.

摘要： Various embodiments described above can enable referral lists to be used in connection with distributed content to protect a referral infrastructure that is used with such content. In at least some embodiments, referral lists are protected using digital rights management (DRM) techniques. The DRM techniques can be used for a number of purposes including securely establishing a referring consumer, securely maintaining a chain of referring entities through distribution tracking, and maintaining control over the referral lists associated with distributed content. In at least some embodiments, DRM techniques are utilized to protect referral lists that are used in multi-level marketing networks.

摘要： Encrypted content streaming is provided by a method comprising holding an encrypted content stream that is cryptographically encrypted from a content stream with a content key, and holding an encrypted content key that is cryptographically encrypted from the content key with one or more blackout encryption keys. Each blackout encryption key is paired to a blackout decryption key corresponding to a specific audience, and each blackout decryption key is obtainable by audiences other than the specific audience corresponding to the blackout decryption key. The method further comprises serving the encrypted content stream to the plurality of different audiences. The encrypted content stream is embedded with a leaf license comprising the encrypted content key, and the encrypted content key is cryptographically decryptable by audiences having the one or more blackout decryption keys paired to the one or more blackout encryption keys.

摘要： In accordance with one or more aspects, a license for content is retrieved, the license having been previously embedded in the content. A requested action is allowed to be performed with the content only if a standalone license, or both a leaf license and a root license, indicate that the action with the content is permissible. Leaf licenses and/or standalone licenses can be embedded by a source of the content and/or by a target device that receives the content. Additionally, licenses can include one or more rules indicating where a target device that receives the content is to store the licenses.

摘要： Content license storage is provided by holding, in a temporary license store on the content consumption device, a plurality of content licenses for a plurality of content streams, wherein each content license of the plurality of content licenses includes a removal date. The method further includes for each content license of the plurality of content licenses corresponding to a content stream of the plurality of content streams which is designated for archived playback, copying the content license into an embedded license store within the content stream to form an archived content stream. The method further includes removing one or more of the plurality of content licenses held at the temporary license store if the removal date included in the content license has been reached, while leaving each content license stored within an archived content stream even if the removal date has been reached.
