Method and apparatus for uniquely identifying a customer purchase in an electronic distribution system

A system for tracking usage of digital content on user devices. Content sites for distributing digital content over a computer readable medium to users. The content sites associate unique content identifier with the content associated. Electronic stores coupled to a network sell licenses to play digital content data to users. The licenses contain a unique transaction identifier for uniquely identifying the transaction, and the licenses contain a unique item identifier for uniquely identifying at least one item in the transaction. Content players, which receive from the network the licensed content data, are used to play the licensed content data. The content players produce a purchase identifier based upon the mathematical combination of the content identifier, the transaction identifier and the item identifier.

Content Metadata Directory Services

The content metadata directory system connects consumers of identified content to managed metadata databases and other digital resources. The system manages links between identifiers in content objects and metadata sources. It supports a variety of different type of content identifiers and allows for overlap among different content identification schemes. One method of associating a content object with metadata uses a combination of a content identifier and a bounding identifier to enable handling of disparate sets of content identifiers for content objects with potentially conflicting content identifiers. The method receives a content identifier for a content object from among a set of content identifiers and provides a unique bounding identifier for the set of content identifiers. This unique bounding identifier is used in combination with the content identifier to form a globally unique identifier for the content object. This globally unique identifier is associated with a metadata source, which enables routing of a user to the metadata source.

Rights management systems and methods using digital watermarking

A digital watermark (DWM) content identifier is steganographically embedded in content. The DWM content identifier provides a link to a rights registry storing usage rights associated with the content. In some implementations the rights registry provides an association between the DWM content identifier and a digital rights management (DRM) content identifier. The DRM content identifier is used to find associated usage rights. The DWM content identifier can also be used to transfer content from a first DRM system to a second DRM system.

Voice over content centric networks

A system for facilitating voice calls over a content centric network (CCN) receives from a CCN user an expressed interest in receiving voice calls directed to the CCN user, wherein information in the CCN can be addressed, located, and disseminated by its content identifier and wherein data packets in the CCN are self-authenticating. Next, the system receives from a second network a packet for a voice call directed to the CCN user. The system then forwards to the CCN user the packet received from the second network with a CCN identifier corresponding to the interest expressed by the CCN user and forwards a packet from the CCN user for the voice call to the second network.

Content Metadata Directory Services

A method of associating a content object with metadata uses a combination of a content identifier and a bounding identifier to enable handling of disparate sets of content identifiers for content objects with potentially conflicting content identifiers. The method receives a content identifier for a content object from among a set of content identifiers. It provides a unique bounding identifier for the set of content identifiers. This unique bounding identifier is used in combination with the content identifier to form a globally unique identifier for the content object. This globally unique identifier is associated with a metadata source, which enables routing of a user to the metadata source. Another novel method addresses content objects with two or more content identifiers, potentially referencing different metadata sources. This method registers different globally unique identifiers for a content object. These globally unique identifiers each comprise a content identifier provided with the content object and a bounding identifier identifying a set of content identifiers of which the content identifier is a member. For each of the globally unique identifiers, information is maintained about a metadata source. The method receives a first content identifier for the content object, and uses a bounding identifier associated with the set of the first content identifier to determine the globally unique identifier for the first content identifier. The user is routed to the metadata source associated with globally unique identifier. This document describes a novel system that enables multiple identity providers (ID Providers) to register and use the system. The ID Provider registers with a metadata directory system, receives a unique bounding identifier, and uses this bounding ID (e.g., an ID provider ID) with subsequent interactions with the metadata directory system. Separately, metadata source providers register metadata sources with the metadata directory system. This enables many different participants to associate content objects with metadata sources using one or more identify providers. Examples of metadata source providers include content providers, like content owners or retailers that have the flexibility of working with different ID providers to associate content objects with metadata. Both content providers and ID providers can register and use the system. The metadata source is the system or device that provides the metadata, like a web site. The directory system uses an identifier for the metadata source, which enables it to maintain an association between a content object and its corresponding metadata source. For example, in some embodiments, a URL serves to identify the location of the source. The Content Metadata Directory Services (CMDS) is a global trusted directory service that connects consumers of identified content to content-provider authorized and managed metadata databases and other digital resources. It includes mostly links to metadata, forms globally unique IDs based upon overlapping content identifiers and unique bounding identifiers, enables multiple content identifiers within a content object, and enables multiple content identity technology providers, even when they are using different technology.

System and method for managing distribution of content to a device

The present invention provides a system and method for managing distribution of content to a device, the system comprising a database for storing a number of elements as a hierarchical structure, content identifiers being able to be associated with elements in the hierarchical structure, and one of the elements representing the device, and a server for referencing the hierarchical structure in the database to generate a profile for the device, the profile containing a number of content identifiers indicating content to be provided to the device. A device manager is associated with the device and arranged to receive the profile from the server and to use the content identifiers in the profile to cause the content indicated by the profile to be provided to the device, a record being kept identifying the content provided to the device in accordance with the profile. The device manager is arranged upon receipt of a subsequent profile from the server to compare the content identifiers in the subsequent profile with the record to determine new content not yet provided on the device and old content no longer to be provided on the device, the device manager being arranged to use the relevant content identifiers to cause the new content to be provided to the device, and to cause the old content to be removed. This approach facilitates the efficient management of distribution of content to devices.

Debugging application performance over a network

An application debugging switch also monitors application performance. The application debugging switch forwards the requests from a first host to a second host, and later forwards the response coming from that second host to that first host. As most of the applications work in a request—response architecture, the application debugging switch can measure the response time of the application. The switch attaches a timestamp to each request that it forwards. When the response to that request comes to the switch, the switch can determine the response time of that application. The application debugging switch collects multiple samples of response time over a certain period of time. These samples provide a good measurement for the average application response time. The response time is a combination of the network response time and the application response time. The application debugging switch holds multiple measurement classes. Each class defines different sources or destinations of traffic (IP addresses and networks) and different applications (TCP / UDP ports or content identifiers in the requests). Collecting the response time for each class separately allows zooming in to an application and user that experience bad service and detect the reason for their failure.

Serving content-targeted ADS in e-mail, such as e-mail newsletters

Content-targeted ads are served with e-mail messages, such as HTML e-mail messages by (i) having the document publisher include a unique content identifier in the content, (ii) having a client device pass the unique content identifier to a content-relevant ad server in a content-relevant ad request, and (iii) having the content-relevant ad server use the unique contend identifier to identify previously registered content for purposes of determining content-relevant ads. In the content-relevant ad server, multiple ads may compete for desired ad attributes (e.g., relative position on a page) or features. An arbitration process may be used to chose and / or order the ads. By having the client device pass the unique content identifier to the content-relevant ad server when it needs the ads, ads can be chosen and generated all at the time the user reads (or more generally “opens”) the e-mail document. This permits up-to-date ad information to be used when serving ads. User actions with respect to served ads may be tracked by (i) using an ad image to display ads in the document, and (ii) using an image map (included in the document originally served) to monitor user behavior with respect to an ad served in a document. All the information about the ad impression may be encoded in a unique identifier, which is returned, along with the ad image. The ad image and unique identifier may be provided to a client device. When a user selects an ad, this unique identifier may be returned to the ad server. A position of an image map clicked may also be returned to the ad server. The returned unique identifier and image position may be used to allow the ad server to determine which ad was selected. Thus, the unique identifier permits a selection to be matched with a previous ad serve.
