摘要： When captured content is detected, the captured content is analyzed to determine whether any portion of the content is subject to digital rights management protection specified for content captured. Responsive to determining that the captured content is subject to a first digital rights management protection, a database is queried to select at least one digital rights management rule associated with a first restricted element specifying at least one first criteria for combining the first restricted element with at least one other element. A determination is made whether the first restricted element is combined with the at least one other element in the captured content. Responsive to detecting the first restricted element is combined with the at least one other element, the captured content rights controller determines a combined digital rights management protection rule reconciling the at least one first criteria for combining the first restricted element with the presence of the at least one other element. The combined digital rights management rule is applied to restrict use of the captured content.

摘要： An apparatus and a method are provided for selectively accessing digital content carried on a distribution medium such as a physical medium or a broadcast medium. In one embodiment, a plurality of digital content items are encrypted under a plurality of different key management blocks, wherein each key management block is associated with a different set of device keys. The plurality of content items may be provided together on a single distribution medium to devices having assigned device keys, so that devices may selectively access content as determined by the different key management block used to encrypt the various content items and by the device keys assigned to the devices. Depending on the association between the device key and the key management blocks, the decoding device may decode all of the content items, some of the content items, or none of the content items. To provide greater security, each content item may be multiple encrypted using multiple key management blocks per content item.

摘要： A captured content rights controller detects a first portion of streaming captured content and a second portion of the streaming captured content after the first portion of the streaming captured content is detected. The captured content rights controller determines whether rendering the second portion of the streaming captured content after the first portion of the streaming captured content is subject to at least one digital rights management protection rule for streaming captured content as specified by at least one owner of at least one restricted element within the streaming captured content captured independent of distribution of the content by the owner of the at least one restricted element within the streaming captured content. The captured content rights controller applies the at least one digital rights management protection rule to restrict rendering of the second portion of the streaming captured content after the first portion of the streaming captured content.

摘要： Provided are techniques for the creation and storage of an archive for binding IDs corresponding to a cluster of devices that render content protected by a broadcast encryption scheme. When two or more clusters are merged, a binding ID corresponding to one of the clusters is selected and a new management key is generated. Binding IDs associated with the clusters other than the cluster associated with the selected binding ID are encrypted using the new management key and stored on a cluster-authorized device in a binding ID archive. Content stored in conformity with an outdated binding ID is retrieved by decrypting the binding ID archive with the management key, recalculating an old management key and decrypting the stored content.

摘要： A method, computer program product, and data processing system for secure automated dispensing of prescription medications are disclosed. A preferred embodiment of the present invention utilizes broadcast encryption to encrypt a prescription for storage on a machine-readable medium that is pre-written with a key management block (KMB). The KMB encodes a session key needed to read from or write to the medium. Each prescription-writing device and medication dispensing device is assigned a unique set of device keys, which are used to recover the session key from the medium. Only authorized devices are able to recover the session key from a medium's KMB. Thus, only authorized devices may read or validly write prescriptions from/to the machine-readable medium. Hence, only authorized providers can write fillable prescriptions and only authorized dispensers can dispense medications to fill those prescriptions.

摘要： Provided are techniques to enable a device that provides a service to authorize a second device for receiving the service and the delivery of the service to the second device and other devices within a trusted network. A signed Management Key Block (MKB) is generated and transmitted over a network. Devices authorized to access a particular service parse the MKB and transmit a request. A server associated with the service determines whether or not the device is authorized to access the service based upon data included in the request. The first device may issue a challenge to the second device for authentication purposes. If service is approved, service is initiated, either from the first device or another authorized device. Devices may be organized into classes such that devices of a specific class are authorized to access the service.

摘要： A message comprising an indication of a management key block and an indication of an authorization table is received at a first network device from a second network device. The indication of the management key block, the indication of the authorization table, and a response message generated based on validating the indication of the management key block and the indication of the authorization table are stored. A second message comprising a second indication of the management key block and a second indication of the authorization table is received at the first network device from the second network device. The first network device communicates with the second network device in accordance with the stored response associated with the first message on determining that the second indication management key block and the second indication of the authorization table match corresponding stored indications of the management key block and the authorization table.
