摘要:
The present invention relates generally to fingerprinting, e.g., a reduced-bit representation or other identifier of a media signal (e.g., audio, video or still images). One method recites: receiving a partial fingerprint of a media signal, wherein the partial fingerprint is derived from the media signal itself, the partial fingerprint being computed a first location; processing the partial fingerprint to obtain a more refined fingerprint, relative to the partial fingerprint, the act of processing occurring at a second location that is remote from the first location; and based at least in part of the refined fingerprint, identifying the media signal or information associated with the media signal. Another method recites: obtaining a fingerprint derived from a media signal, the fingerprint comprising a reduce-bit representation of the media signal; determining information associated with the fingerprint or the media signal; and causing a text message to be sent to a mobile device representing at least a portion of the information. Of course, other methods and combinations are described and claimed as well.

A portable device for use with audio or visual content (e.g., an MP3 player-like device, or a camera-enabled device) is equipped with one or more features/capabilities, including: a user interface through which a consumer can instruct that content be delivered to a different consumer's device, the ability to derive identifiers from content and take action(s) based thereon, the ability to count playbacks of content; and/or the ability to interact with remote web services. A variety of other features and arrangements are also detailed.

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.

The present invention relates watermarking compressed objects. A watermark is determined for a compressed video object. The watermark is compressed as an object and the watermarked object is then associated with the compressed video object. The two separate objects are provided to a rendering device, which after decompressing both objects, embeds the watermark in the video prior to rendering.
摘要:
Digital watermarking or steganographic data hiding is used to convey location data in video. A digital watermark or steganographic signal may associate geovector or geolocation information with video, video objects or areas depicted in the video. Other implementations and combinations are provided as well.

摘要:
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.

This disclosure details systems and methods for embedding and reading auxiliary code signals in documents, and for using the code signals to enable a variety of forensic tracking, monitoring and usage control functions.
摘要:
A method of performing digital asset management of content is provided. The content is identified with an identifier. The identifier can be identified with a digital watermark, header file, or both. The identifier is linked to usage rules to regulate usage and protect the content. The usage rules can be maintained on a remote or local database or server. Once extracted, an identifier is used to index the database to locate a corresponding usage rule, and can be used to override copy control information with proper purchase and subsequent protection. Content can be managed from such. In another embodiment, an identifier is used to track usage, such as amount of content viewed, time played, and copies made. In yet another embodiment, a content identifier is used to regulate content throughout a distribution chain, and a distributed set of databases with information relevant only to the owner of the database act as one database due to a central router.
