摘要:
An architecture for an integrated shopping service that enables electronic shopping from within a software application. The software application includes web browsing functionality, with the capability to navigate to a limited set of web sites. The client machine on which the software runs maintains a local list of the limited set of web sites that can be accessed from within the software application. A directory server maintains a list of retail web sites that can be added to the client's local list of accessible web sites. Each client machine that runs the software application connects to the directory server in order to add web sites to the locally-maintained list of sites that can be accessed from within the integrated shopping service.

A first trusted component on a first computing device performs cryptography, evaluation, and enforcement and is tied thereto, and a first user-machine certificate associated with the first computing device is tied to a user. Correspondingly, a second trusted component on a second computing device performs cryptography, evaluation, and enforcement and is tied thereto, and a second user-machine certificate associated with the second computing device is also tied to the user. The first trusted component obtains the content for rendering on the first computing device by way of the first user-machine certificate and the license, and the second trusted component obtains the content for rendering on the second computing device by way of the second user-machine certificate and the same license.

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:
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.

Embodiments are described for capturing, displaying, and navigating text annotations in a non-modifiable document. In some embodiments, a determination is made that a text annotation is to be created and a system determines the file position of the selected object. The file position of the selected object can be stored along with the created text annotation in another file or a non-read only portion of a file storing the document. Using the file position, the text annotation may be identified with the selected object without modifying the non-modifiable document. In some embodiments, once a text annotation is displayed a user may easily navigate among the captured annotations.
摘要:
A licensor receives a request from a requestor including an identifier identifying the requestor and rights data associated with digital content, where the rights data lists at least one identifier and rights associated therewith. The licensor thereafter locates the identifier of the requestor in a directory, and locates in the directory based thereon an identifier of each group which the requestor is a member of. Each of the located requestor identifier and each located group identifier is compared to each identifier listed in the rights data to find a match, and a digital license to render the content is issued to the requestor with the rights associated with the matching identifier.
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 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:
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.
