Abstract: Methods and apparatus for managing rights associated with digital content in a digital exchange system (e.g., a content management system) are provided. The method includes providing one or more first templates, and providing one or more second templates. Each first template corresponds to one or more rights of a first digital rights management system, and each second template corresponds to one or more rights of a second digital rights management system. The method further includes relating one or more of the first templates to one or more of the second templates based on pre-determined criteria.

Abstract: Encryption and decryption of data stored from a computing system to a storage medium is disclosed wherein the processing employs a non-accessible encryption key that is unique to the computing system. The unique encryption key can be embedded in non-removable hardware of the computing system or generated, e.g., from identification numbers ascertained from non-removable hardware of the computing system. Processing includes establishing the unique encryption key, encrypting data using the unique encryption key and storing the encrypted data to the storage medium without storing the unique encryption key on the storage medium. The storage medium can comprise any non-removable or removable storage medium, including for example a computer hard drive, floppy diskette, or recordable compact disk.

Abstract: Embodiments of the present invention provide for flexible monitoring of content. The content at a client device can be monitored based on the use and actions performed by the client. In order to monitor the content at the client, a dependency is created between any recipient of the content and a monitor installed at the client device. For example, the content may be encrypted and, when the content is accessed by a potential recipient, the recipient may be required to request a key from the monitor. This activates the monitor to begin recording transaction data and events about the content's use, such as the recipient's identity and the type of actions performed. The monitor can be configured to passively monitor and record the use of the content at the client's device. In addition, the monitor can be configured to provide audit data that indicates the transaction data recorded to a server.

Abstract: A method, system and computer readable medium for the blocking of recording digital content at an end user multimedia end-user-system during the rendering of encrypted digital multimedia files. Before the process of rendering of encrypted digital multimedia can be started all rendered media stream during playback are opened to ensure that this multimedia content is not recorded. This blocks the usage of the multimedia interfaces including devices and/or ports that can be used to store un-encrypted content that has been decrypted for the purposes of playing or rendering. The method also includes an exception, which allows recording with permission from the present invention.

Abstract: A system and method for managing simultaneous access to a scarce or serially re-usable resource by multiple process threads. A stationary queue is provided, including a wait counter for counting the cumulative number of threads that have been temporarily denied the resource; a satisfied counter for counting the cumulative number of threads that have been denied access and subsequently granted access to said resource; a sleep code routine responsive to the wait counter for generating a run identifier; and a wakeup code routine responsive to the satisfied counter for generating the run identifier.
