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.

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.

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.

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.

A method of indexing content for network searching comprises identifying media content signals stored at sites distributed over a distributed computer network; extracting content identifiers from the content signals; using the content identifiers to obtain metadata used to classify the media content signals; and creating a searchable index of the media content signals based on the metadata, wherein users access the searchable index on the distributed computer network to submit a search query for the searchable index to retrieve links to the media content signals.

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.

A method for routing data at a first node of a network including a second node. The method includes: providing the first node with a database storing an association between: an URL component identifying content at the first node, and a unique identifier associated to the second node, the unique identifier being specified by the second node; registering content locally stored in the second node by storing in the database an association between an URL component identifying the locally stored content and the unique identifier of the second node; and, upon reception from a requesting entity, by the first node, of a content request having a content identifier, the method includes: checking in the database whether the content identifier includes the URL component, and forwarding the content request to the second node if the content identifier includes the URL component associated with the unique identifier of the second node.

A method of indexing content for network searching comprises identifying media content signals stored at sites distributed over a distributed computer network; extracting content identifiers from the content signals; using the content identifiers to obtain metadata used to classify the media content signals; and creating a searchable index of the media content signals based on the metadata, wherein users access the searchable index on the distributed computer network to submit a search query for the searchable index to retrieve links to the media content signals.

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.

Content identifiers are associated with respective metadata. Through use of the metadata, a user's experience with the content can be enhanced. A variety of other arrangements are also detailed.

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.

An arrangement (100) and a method are disclosed for sharing a content item (101), such as a music title, with a second user. A first user (110) grabs a piece of music from the title and sends said piece of music to a friend (130). The user device (110) adds a content identifier and a user identifier identifying the sender to the transmitted piece of music. The recipient reproduces the piece of music (102). If he or she subsequently decides to buy the complete title, the sender will obtain an award from the content owner (130) for promoting the title. This electronic version of "mouth-to-mouth" marketing encourages people to spread music clips and may persuade friends to purchase content items.

Content identifiers are associated with respective metadata. Through use of the metadata, a user's experience with the content can be enhanced. A variety of other arrangements are also detailed.

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.

A proxy server and corresponding method are provided for managing the controlled distribution of digital content as it propagates through a social network. A proxy server receives digital content and associated distribution parameters from an originating peer. The distribution parameters define access rights for n allowable levels of possible network distribution. After other peers are invited to share the digital content or the invited peers request access to the digital content, the proxy server generates a rights-managed form of the requested digital content in accordance with the access rights established by the originating peer for the level associated with the requesting peer(s). The proxy server forwards a copy of a content key and other content identifiers to an associated license server and then sends the rights-managed form of digital content to the requesting peer(s).

A relay apparatus on a network includes an analysis section that analyzes multimedia contents transmitted from a contents provider. The relay apparatus temporarily stores contents identifiers, component information of the contents, and element data pointed by pointers of the component information, and creates a transmission sequence for transmitting the element data. A transmission section transmits the contents identifier, the contents component information and the element data according to the transmission sequence to a service provider. When the relay apparatus receives a request from a terminal or from a service provider even before the service provider completes registration of the entire multimedia contents, the relay apparatus or the service provider can start rendering multimedia transmission services to the terminal.

In a server serving as an information distribution apparatus and an information communication terminal, contents are managed by using content identifiers (content IDs) managed as IDs conforming to a rule of uniformity. Particularly, in the information communication terminal, a content ripped from a recording medium such as a CD, and stored in a storage element, such as a hard disk drive, is also managed by using a content identifier acquired from the information distribution apparatus. In this way, contents stored in the storage element can be managed by using content IDs each managed as an ID common to the information communication terminal and the information distribution apparatus. In communication between the information communication terminal and the information distribution apparatus, a content identifier conforming to a rule of uniformity is used for identifying a content to which the content identifier is assigned, so that the terminal is capable of downloading the content as well as acquiring additional information relevant to the content from the apparatus.
