8,843,414, "Techniques for accessing controlled media objects," assigned to Ricoh Company, Ltd. (JP).
Abstract
Techniques for managing media objects are provided. The techniques include providing an algorithm configured to generate an identifier (ID) based on content of a first media object. The ID is then generated for the first media object. The ID allows the first device to identify the first media object to a second device. The second device is configured to use the ID to determine if a second media object associated with the ID is accessible to the second device. Also, the determination is made notwithstanding source information for the first and second media objects or digital rights restrictions imposed on the first and second media objects, where the first media object and second media object include substantially identical content.8,843,413, "Binding content to a domain." Assigned to Microsoft.
Abstract
The present invention provides for a digital rights management system with a centralized domain service capable of creating and managing membership criteria for joining a domain in accordance with business rules defined by a content owner. A domain identification is created that allows a content provider to uniquely bind content licenses to a domain. The content licenses include usage rights that define how content associated with the licenses may be consumed by one or more members of the domain. The centralized domain service can enforce digital rights by validating membership criteria including at least one of a domain proximity check for validating that a requestor is in close proximity to the domain, a total number of requestors, or the frequency that the requests have been made by various requestors to join the domain and unjoin from the domain.
