摘要： A method for managing rights in digital content includes generating rights data for a piece of digital content and forming a piece of rights managed digital content by associating the rights data with the piece of digital content. The rights data includes parameters that govern the terms on which the content may be licensed, and may include a list of entities to which the content may be licensed, a respective set of one or more rights that each such entity has in the digital content, and any conditions that may be placed on those rights. A method for licensing rights managed digital content includes receiving a license request for a license to use the piece of rights managed digital content, where the license request includes such a signed rights label. The digital signature on the signed rights label is validated to determine whether a trusted entity issued the signed rights label. If a trusted entity issued the signed rights label, a license to use the piece of rights managed digital content in accordance with the rights data may be issued.
摘要翻译： 用于管理数字内容中的权利的方法包括通过将权利数据与该片数字内容相关联来生成一段数字内容的权限数据，并形成权限管理的数字内容。 权利数据包括控制内容可以被许可的术语的参数，并且可以包括内容可以被许可的实体的列表，每个这样的实体在数字内容中具有的一个或多个权限的相应集合， 以及可能针对这些权利的任何条件。 许可权管理数字内容的方法包括接收许可证的许可证请求以使用该版权管理的数字内容，其中许可请求包括这样的签名权利标签。 对签名的权利标签上的数字签名进行验证，以确定信任的实体是否签发了签名的权利标签。 如果可信实体签发了签名的权利标签，则可以颁发根据权利数据使用该版权管理的数字内容的许可。

摘要： A first device is used to initiate and direct a rights-management transaction, such as content licensing, acquisition, or activation, on behalf of a second device. The first device may, for example, be a desktop computer, laptop computer, or electronic kiosk at a bricks-and-mortar store. The second device may, for example, be a handheld computer that is cradled to establish communicative connectivity with the first device. A user interacts with the first device to initiate a transaction on behalf of the second device. The first device then obtains the information from the second device that is necessary to perform the transaction on behalf of the second device, communicates with a server, and provides the result of the server communication to the first device. Thus, the first device acts as a proxy for the second device.

摘要： A server architecture for a digital rights management system that distributes and protects rights in content. The server architecture includes a retail site which sells content items to consumers, a fulfillment site which provides to consumers the content items sold by the retail site. The fulfillment site includes an asynchronous fulfillment pipeline which logs information about processed transactions using a store-and-forward messaging service. The fulfillment site may be implemented as several server devices, each having a cache which stores frequently downloaded content items, in which case the asynchronous fulfillment pipeline may also be used to invalidate the cache if a change is made at one server that affects the cached content items.

摘要： Content is encrypted according to a content key (CK) to result in (CK(content)) and the content key (CK) is protected according to a public key for a license server (PU-RM). Rights data is retrieved from a rights template to be associated with the content, and rules for modifying the retrieved rights data are also retrieved from the retrieved rights template. The retrieved rights data from the rights template is modified according to the rules, and the rights data and the protected content key (CK)) are submitted as a rights label to the license server for signing thereby. The license server thus validates the rights label and, if valid, creates a digital signature based on a private key (PR-RM) corresponding to (PU-RM) and based at least in part on the rights data to result in a signed rights label (SRL), and returns the SRL.

摘要： A server architecture for a digital rights management system that distributes and protects rights in content. The server architecture includes a retail site which sells content items to consumers, a fulfillment site which provides to consumers the content items sold by the retail site, and an activation site which enables consumer reading devices to use content items having an enhanced level of copy protection. Each retail site is equipped with a URL encryption object, which encrypts, according to a secret symmetric key shared between the retail site and the fulfillment site, information that is needed by the fulfillment site to process an order for content sold by the retail site. Upon selling a content items, the retail site transmits to the purchase a web page having a link to a URL comprising the address of the fulfillment site and a parameter having the encrypted information. Upon the following the link, the fulfillment site downloads the ordered content to the consumer preparing the content if necessary in accordance with the type of security to be carried with the content. The fulfillment site includes an asynchronous fulfillment pipeline which logs information about processed transactions using a store-and-forward messaging service. The fulfillment site may be implemented as several server devices, each having a cache which stores frequently downloaded content items, in which case the asynchronous fulfillment pipeline may also be used to invalidate the cache if a change is made at one server that affects the cached content items. An activation site provides an activation certificate and a secure repository executable to consumer content-rendering devices which enable those content rendering devices to render content having an enhanced level of copy-resistance. The activation site “activates” client-reading devices in a way that binds them to a persona, and limits the number of devices that may be activated for a particular persona, or the rate at which such devices may be activated for a particular persona.

摘要： A digital rights management system for the distribution, protection and use of electronic content. The system includes a client architecture which receives content, where the content is preferably protected by encryption and may include a license and individualization features. Content is protected at several levels, including: no protection; source-sealed; individually-sealed (or “inscribed”); source-signed; and fully-individualized (or “owner exclusive”). The client also includes and/or receives components which permit the access and protection of the encrypted content, as well as components that allow content to be provided to the client in a form that is individualized for the client. In some cases, access to the content will be governed by a rights construct defined in the license bound to the content. The client components include an object which accesses encrypted content, an object that parses the license and enforces the rights in the license, an object which obtains protection software and data that is individualized for the client and/or the persona operating the client, and a script of instructions that provides individualization information to a distributor of content so that the content may be individualized for the client and/or its operating persona. Content is generally protected by encrypting it with a key and then sealing the key into the content in a way that binds it to the meta-data associated with the content. In some instances, the key may also be encrypted in such a way as to be accessible only by the use of individualized protection software installed on the client, thereby binding use of the content to a particular client or set of clients.

摘要： Disclosed is a method for dynamically applying a rights management policy to a message by allowing an administrator to associate certain rights management policies with certain senders and recipients of messages, with groups of users possessing certain common criteria which define the users and groups of users, with certain attributes of the message, and with certain environmental attributes. Also disclosed is a method for allowing an administrator to automatically update a rights management protected message as it passes through a message transfer agent. The administrator may determine either on a regular interval or an ad-hoc basis that the message transfer agent scan the messages stored to determine whether or not the content has expired. If the content has indeed expired the administrator may take steps to have the expired content deleted entirely, refreshed with more current content, or replaced with a tombstone indicating that the original content has expired.
