    摘要: A header object for a data file is comprised of sub-objects which specify properties of the data stream and contains information needed to properly verify and interpret the information within the data object. In order to allow the protection of any set of sub-objects without requiring that the sub-objects follow any specific ordering, a new sub-object is introduced which includes region specifiers identifying regions within sub-objects and verification information for those regions. This new sub-object in the header object allows the modification of non-protected regions and reorganization of sub-objects in a header without invalidating verification information.

    摘要: This document describes policies for digital rights management that enable distribution of full-function versions of applications that, while fully functional, have functions limited by an associated policy. A policy may be replaced or updated, thereby enabling use of previously limited functions without distribution of another version of the application.

    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: Metering is enabled through an arrangement in which a metering certificate is communicated to a mobile device using an over-the-air protocol. A metering trigger provides the metering certificate that includes a location to which metering data is posted by the mobile device and a public key of a public-private key pair, or alternatively provides a link to such metering certificate. A metering helper passes the metering certificate to a DRM system on the mobile device which collects metering data associated with the metering ID and uses the public key to encrypt the metering data into a metering challenge. The metering helper posts the metering challenge to the location. The metering service extracts the metering data from the metering challenge using a private key and generates a metering response that is received by the metering helper which prompts the DRM system to reset at least a portion of a data store in which the metering data is stored.

    摘要: A computing device has encrypted content and a corresponding license having a decryption key for decrypting the content. The license allows the computing device to render the content thereon. The computing device may issue a sub-license based on the license to a portable device. The sub-license allows the portable device to render the content thereon and has the decryption key. The portable device has a digital device certificate including information thereon. The computing device receives from the portable device the device certificate thereof, and determines based on rules in the license and the information on the portable device in the device certificate whether the computing device can issue the sub-license to the portable device. If so, the computing device constructs such sub-license to include the decryption key (KD) and transmits the constructed sub-license to the portable device.
