    摘要: One or more files of an application are obtained and configured as a virtual storage volume. An application package is generated by encrypting, using a key, the one or more files configured as a virtual storage volume. A license generation module generates a license including both a usage policy for the application and the key. A computing device, to run the application, obtains and attempts to authenticate the application package. If the application package is authenticated, then a license associated with the application package is obtained and at least part of the application package is decrypted using the key in the license. A virtual storage volume that includes the application is mounted, and the application is executed in accordance with the usage policy in the license. However, if the application is not authenticated, then the application is not executed.

    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: A content license associated with unencrypted digital content is generated, the content license including both an identifier of the unencrypted digital content and a content policy. At a user device, a determination is made as to whether the content license corresponds to particular unencrypted digital content. Use of the particular unencrypted digital content by the computing device is permitted in accordance with the content policy if the content license corresponds to the particular unencrypted digital content. However, use of the particular unencrypted digital content by the computing device based on the content license is prohibited if the content license does not correspond to the particular unencrypted digital content.

    摘要: Data such as a musical track is stored as a secure portable track (SPT) which can be bound to one or more players and can be bound to a particular storage medium, restricting playback of the SPT to the specific players and ensuring that playback is only from the original storage medium. The SPT is bound to a player by encrypting data of the SPT using a storage key which is unique to the player, is difficult to change, and is held in strict secrecy by the player. The SPT is bound to a particular storage medium by including data uniquely identifying the storage medium in a tamper-resistant form, e.g., cryptographically signed. The SPT can also be bound to the storage medium by embedding cryptographic logic circuitry, e.g., integrate circuitry, in the packaging of the storage medium. The SPT is bound by encrypting an encryption key using the embedded logic. By using unique cryptographic logic, only that particular storage medium can decrypt the encryption key and, therefore, the data of the SPT encrypted with the encryption key. To allow a user to playback the SPT on a number of players, players can share storage keys with one another. Such key sharing is done in a cryptographically secure manner. Before downloading an SPT to a particular external player, the ability of the external player to enforce restrictions placed upon the SPT is verified.
