    摘要: A first surface optical disk is disclosed that has machine readable code information, such as bar code information, disposed thereon to permit a disk drive or other device to obtain certain basic information regarding the disk in an efficient and reliable manner. The machine readable code may include error detection and error correction code to correct errors, such as those caused by surface dust, that may arise during reading the machine readable code. The machine readable code may be disposed within a portion of a ring on the optical disk. Human readable alphanumeric characters, including graphics, identifying the side of the optical disk and other basic information may also be disposed within the ring.

    摘要: The present invention relates to digital rights management (DRM) for content that may be downloaded and securely transferred from one storage to another storage. The storage may be a disk drive, or network attached storage. The storage performs cryptographic operations and provides a root of trust. The DRM system enables secure copying or transfer of content from one storage device to another storage device. In this embodiment, a trusted server that is authenticated and trusted by both storage devices brokers the transfer of content. The trusted server may be a separate entity of the DRM system or may be a component or function of an existing server of the DRM system. In another embodiment, the storage devices may transfer content in a peer-to-peer fashion. The transfer of content may be authorized and controlled based on a digital certificate associated with the content.

    摘要: The present invention relates to digital rights management (DRM) for content that may be downloaded and bound to a storage device. The storage device may be an intelligent storage device, such as a disk drive, or network attached storage. In addition, the storage device is capable of performing cryptographic operations and providing a root of trust. In one embodiment, the DRM employs a binding key, a content key, and an access key. The binding key binds the content to a specific storage and is based on a key that is concealed on the storage. However, the binding key is not stored on the storage with the content. The content key is a key that has been assigned to the content, for example, by a trusted third party. The access key is determined based on a cryptographic combination of the content key and the binding key. In one embodiment, the content is encrypted based on the access key and stored in encrypted form in the storage device.
