`
`RELATED APPLICATION DATA
`
`[0001] This application is a continuation of U.S. patent
`application Ser. No. 11/208,441, filed Aug. 19, 2005 (pub-
`lished as US 2006-0062426 A1), which is a continuationin
`part of U.S. patent application Ser. No. 10/126,921, filed Apr.
`18, 2002 (published as US 2002-0186844 Al). The Ser. No.
`10/126,921 application also claims the benefit of U.S. Patent
`Application Nos. 60/285,514, filed Apr. 20, 2001 and 60/315,
`569,filed Aug. 28, 2001. Each of the above-mentioned patent
`documents is hereby incorporated by reference.
`[0002] This applicationis also related to the present assizn-
`ee’s U.S. Pat. No. 6,505,160, published U.S. Patent Applica-
`tion Nos. US 2002-0052885 Al and US 2003-0056103 Al,
`and provisional patent application No. 60/256,628. Each of
`the above-mentioned patent documents is hereby incorpo-
`rated by reference.
`
`TECHNICALFIELD
`
`[0003] The present invention relates to integrating content
`identifiers with digital rights management systems. The
`present inventionalsorelates to multimedia signal process-
`ing, such as steganographically encoding auxiliary informa-
`tion into media signals, and decoding the auxiliary informa-
`tion from the media signals.
`
`BACKGROUND AND SUMMARYOF THE
`INVENTION
`
`[0004] Managementofdigital assets becomes an increas-
`ingly difficult challenge as digital content proliferates. The
`term “content” is broadly defined herein and may include
`audio, video, images, electronic data, biometric information,
`graphics and designs, electronic documents, copyrighted
`materials, software, multimedia content,etc., etc. Sometimes
`weinterchangeably use the term “media”for “content” in this
`document. Enhancements in computer networking and data-
`base technology allow companies to manage large content
`collections and to make the content available tothird parties.
`While network communication provides a powerful tool to
`enable a database manager to share content with others, it
`makes it more difficult to control and track how the contentis
`being used.
`[0005]
`For example, some companies maintain extensive
`content databases to promote their products. Customers or
`service providers such as advertising and marketing firms can
`access this content remotely via an internet, extranet, web
`site, intranet, LAN, WAN, wireless network orfile transfer
`transactions. Although computer networking telecommuni-
`cation technology facilitates access, it makes it difficult to
`ensure that customers and services providers are getting the
`latest content, and that they are getting accurate and helpful
`informationrelating to the content.
`[0006] There is a need to enable digital rights management
`systems to reliably link content with additional, related
`data—includingrelated content. The terms “link” and “link-
`ing” are defined broadly herein to include associating, point-
`ing to, facilitating the access of, linking, connecting or con-
`necting to, revealing a storage address of, and/or facilitating
`database interrogation, etc. There is also a need for a digital
`rights management system to reliably link content with
`related usagebilling information. One way to associate con-
`
`tent with information about the contentis to place the infor-
`mation in a file header or footer (we interchangeably use the
`terms “header” and “footer” in this application). This
`approachis notterribly attractive because the added informa-
`tion often does not survivefile format changes, conversion to
`the analog domain, andis susceptible to being stripped away,
`etc. We believe that an improved approach to associate con-
`tent with related data is to steganographically hide identifying
`information within the content. One example of steganogra-
`phy is digital watermarking.
`[0007] Digital watermarking is the science of encoding
`physical and electronic objects with plural-bit digital data, in
`such a manner that the data is essentially hidden from human
`perception, yet can be recovered by computer analysis. Most
`commonly, digital watermarking is applied to media such as
`images, audio signals, and video signals. However, it may
`also be applied to other types ofdata, including documents
`(e.g., through line, word or character shifting), software,
`multi-dimensional graphics models, and surface textures of
`objects. In physical objects, the data may be encodedin the
`form ofsurface texturing, or printing. Such marking can be
`detected fromoptical scan data, e.g., from a scanner, optical
`reader, input device, digital camera, or web cam. In electronic
`media (e.g., digital audio or imagery—including video), the
`data may be encodedas slight variations in sample values. Or
`if the media is represented in a so-called orthogonal domain
`(also termed “non-perceptual,” e.g., MPEG, DCT, wavelet,
`etc.), the data may be encodedas slight variations in quanti-
`zation values or levels. The assignee’s U.S. Pat. Nos. 5,862,
`260, 6,122,403 and 6,614,914 are illustrative ofcertain digital
`watermarking technologies and are each hereby incorporated
`by reference. A great many other approaches are familiar to
`those skilled in the art. The artisan is presumed to be familiar
`with the full range of literature about steganography, data
`hiding and digital watermarking.
`[0008] Digital watermarking systems typically have two
`primary components: an encoder that embeds the watermark
`ina host media signal, anda decoderthatdetects and reads the
`embedded watermark froma signal suspected of containing a
`watermark (e.g., a suspect signal). The encoder embeds a
`watermarkby altering the host media signal. For example, the
`encoder (or embedder) component embeds a watermark by
`altering data samples of the media content in the spatial,
`temporal or someother transform domain (e.g., Fourier, Dis-
`crete Cosine, Wavelet Transform domains). The decoder
`component analyzes a suspect signal to detect whether a
`watermark is present. In applications where the watermark
`encodes information, the decoder extracts this information
`from the detected watermark.
`
`[0009] The analysis of the detected data can be accom-
`plished in various known ways. Presently, most stegano-
`graphic decoding relies on general-purpose microprocessors
`that are programmed by suitable software instructions to per-
`form the necessary analysis. Other arrangements, such as
`using dedicated hardware, reprogrammable gate arrays, or
`other techniques, can of course be used.
`[0010] According to one aspect ofour invention, a digital
`watermarking system includes (or communicates with) a sec-
`ondary component—a database. Such a database preferably
`includes data related to content. The related data may include,
`e.g., content owneror copyright information, metadata, usage
`rights, enhanced or interactive content, and billing informa-
`tion, etc. (The terms “usage rights” (or interchangeably:
`“usage rules”) are broadly intended in this application. Usage

`enables the content owners to be properly paid, and users to
`share content, instead of merely prohibiting use of the con-
`tent.
`
`rights identify permissible (or restricted) actionsor uses asso-
`ciated with content. A few of the many examples include play
`control, encryption requirements,
`rendering restrictions,
`required permissions, etc.) The above related data is prefer-
`ably organized or linked according to respective content iden-
`tifiers. For example, if the content includes a song and the
`related data includes usagerules, then the usage rules can be
`associated with the song via a contentidentifier that is unique
`to the song or to a class ofrelated songs. The database can be
`stored locally, remotely, or both. The database can also be
`distributed, with different databases stored in different net-
`worksor locations, such as a complete central and mirrored
`database and local databases including only subsets of the
`related data on a local computer. Of course our usage of the
`term database throughout this document is broad enoughto
`include software-based databases, data structures, data
`records, etc., etc.
`
`[0013] Oneaspect ofthe present invention provides content
`owners with copy protection security and royalty tracking,
`and end-users with an easy-to-use systemthat improves cur-
`rent content distribution methods, such as CD, DVD and
`VHS. A combination of watermarking and DRM techniques
`can be employed. where a watermark allows content to leave
`and be found outside an associated DRM package without
`harming the security of the system, The watermarkidentifi-
`cation canlink the contentto the usagerules, and, optionally,
`the usage rules can dictate whether the content should be
`re-packagedinto the DRM packageif found outsideofit. This
`means that content found outside the DRM package can be
`purchased and used, as well as re-secured, as opposed to that
`content being considered illegal and perhaps destroyed. This
`inventive feature increases the revenue generated from the

`permissible content use, e.g., such as regulating printing,

`content tracking and data management. In another embodi-
`ment, digital watermarks are used in connection with DRM

`method ofperforming digital asset management of media
`content. In even another embodiment the copy protection
`state (also known as copy control information including copy

`[0015] Yet anotheraspectofthe present invention provides
`a method of associating content with usage rights. The con-
`tent includes a digital watermark (DWM) having a DWM
`content identifier. The method includes: associating a digital
`rights management (DRM) content identifier with the water-
`marked content; populating a first rights registry with usage
`rights associated with the content, wherein the usage rights
`are indexed in thefirst rights registry according to theDRM
`content identifier; and populating a second rights registry
`with the DRM content identifier, wherein the DRM content
`identifier is indexed according to the DWM contentidentifier.

`Still another aspectofthe presentinvention provides
`a method comprising: receiving raw content exported from a
`first digital rights management (DRM) system; detecting a
`content identifier steganographically embedded in the raw
`content: using the content identifier and information associ-
`ated with a second, different DRM system to obtain usage

`rights that are compatible with the second, different DRM
`system; receiving the usage rights; and providing the raw
`content and the usage rights to the second, different DRM
`system.
`Still other aspects ofthe present invention provide a
`[0017]
`method to control a media server. The method includes, upon
`receiving a request to access raw content, searching the raw
`content fora contentidentifier steganographically embedded
`therein. Ifa contentidentifier is found: the method accesses a
`
`rights registry for usage rights associated with the content
`identifier; receives the usage rights from the rights registry:
`presents the usagerights for user acceptance; and upon accep-
`tance ofthe usage rights, provides the usage rights and raw
`contentto a resident digital rights management (DRM) sys-
`tem to control access ofthe content.

`DETAILED DESCRIPTION
`
`Rights Management System
`[0042] With reference to FIG, 1, a rights managementsys-
`tem preferably includes four steps. In step 51, content,
`whether within an encryption package or not, is identified
`before rendering. (“Rendering”here hasits familiar meaning
`ofpresenting for visual and/or audible inspection, e.g., ona

`usage rules). In general, usage rules define the scope of per-
`mitted use for respective content. Examples of usage rules
`include the scope of permissible copying, rendering, trans-
`ferring, altering, playing, viewing, printing, distributing,
`using, etc. Content identifiers can be used to organize a data-
`base that is maintained locally or remotely (e.g., a central
`usage system). Onceextracted fromcontent, an identifier can
`be thenusedto interrogate the database toretrieve the usage
`rules. Content usage is regulated based onits corresponding
`usage rules.
`[0044] Content usage can be tracked via anidentifier in step
`53. This usage tracking can be used, e.g., for proper billing to
`the consumer and payment to content owners and providers.
`Tracking can be incremental or per content item. In one
`embodiment, each video frame or every nth frame (or audio
`segment) is uniquely or redundantly identified. Tracking
`identifiers per frame (or audio segment)allows for a “pay-as-
`you-go” system, in that a consumercan be billed for only the
`amount of content they view, access or listen to. In another
`embodiment, billing is based on a one-time access fee.
`[0045] Asa fourth and optional step (step $4), if contentis
`found outside of its respective DRM, andit should be in the
`DRM packageas dictated by related usage rules, the content
`identifier can help facilitate repackaging of the content in a
`DRMcontainer. Initially, the identifier will help identify the
`content. The identifier can also identify or point to a specific
`package or packaging protocol, or the identifier can link to
`repackaging requirements. An identifier can also be linked to
`usage rules, which can regulate content usage, even for con-
`tent outside of a package. Examples ofcontent being located
`outside of a container include transferring the content to a
`different medium, or converting froma digital format to an
`analog format. Since the contentidentifier is content specific,
`e€.g.,
`it is associated with the content and not the container,it
