`(54) Title: SYSTEM FOR TRACKING END—I.lSER ELECTRONIC CONTENT USAGE
`
`
`
`(57) Abstract
`
`A system for tracking usage of digital content on user devices. Electronic stores coupled to 2 network sell licenses to play digital
`content data to users. Content players, which receive from the network the licensed content data, are used to play the licensed content data.
`Additionally, a logging site. that is coupled to due network tracks the playing of the content data.
`In particular. the logging site receives
`play information from the network, and the play information includes the number of times that the content data has been played by the
`associated content player. Also provided is a method for tracking usage of digital content on user devices. Accorcling to the method. a
`license to play digital content data is sold to a user, and the iiccnsed content data is transmitted to a content player for the user. Further.
`information is tratistnitted to a logging site whenever the content dam is played by the content player or copied from the content player to
`an external medium so that usage of the licensed content data can be tracked.

`SYSTEM FOR TRACKING END-USER ELECTRONIC CONTENT USAGE
`
`BACKGROUND OF THE INVENTION
`
`I.
`
`Field of the invention
`
`The invention disclosed broadly relates to the field of electronic commerce and more particularly to a
`
`system and related tools for the secure delivery and rights management of digital assets. such as print media. films.
`
`games. and music over global communications networks such as the Internet and the World Wide Web.
`
`2.
`
`Description of the Related Art
`
`The use of global distribution systems such as the Internet for distribution of digital assets such as music.
`
`film, computer programs. pictures. games and other content continues to grow. At the same time owners and
`
`publishers of valuable digital content have been slow to embrace the use ofthe Internet for distribution of digital
`
`assets for several reasons. One reason is that owners are afraid of unauthorized copying or pirating of digital
`
`content. The electronic delivery of digital content removes several barriers to pirating. One barrier that
`
`is
`
`removed with electronic distribution is the requirement of the tangible recordable medium itself (_e.g.. diskettes or
`
`CD ROMs).
`
`It costs money to copy digital cotttent on to tangible media. albeit. in many cases less than a dollar for
`
`a blank tape or recordable CD. However, in the case of cl cctronic distribution. the tangible medium is no longer
`
`needed. The cost of the tangible medium is not a factor because content is distributed electronically. A second
`
`barrier. is the format of the content itself i.e. is the content stored in an analog format versus a digital format.
`
`Content stored in an analog format, for example. a printed picture. when reproduced by photocopying. the copy is
`
`of lesser quality than the original. Each subsequent copy of a copy, sometimes called a generation, is of less
`
`quality than flee original. This degradation in quality is not present when a picture is stored digitally. Each copy.
`
`and every generation of copies can be as clear and crisp as the original. The aggregate effect of perfect digital
`
`copies combined with the very low cost to distribute content electronically and to distribute content widely over the
`
`Internet makes it relatively easy to pirate and distribute unauthorized copies. With a couple of keystrokes. a pirate
`
`can send hundreds or even of thousands of perfect copies of digital content over the Internet. Therefore a need
`
`exists to ensure the protection and security of digital assets distributed electronically.
`
`Providers of digital content desire to establish a secure. global distribution system for digital content that
`
`protects the rights of content owners. The problems with establishing a digital content dis1.ri hution system includes
`
`developing systerns for digital content electronic distribution, rights management. and asset protection. Digital
`
`content that is distributed electronically includes content such as print media. films. games, programs. television,
`multimedia, and music.
`
`The deployment of an electronic distribution system provides the digital content providers the ability to
`
`achieve fast settlement of payment through immediate sales reporting and electronic reconciliation as well as gain

`
`secondary sources of revenue through redistribution of content. Since the electronic digital content distribution
`system is not affected by physical inventory outages or returns. the digital content providers and retailers may
`realize reduced costs and improved margins. Digital content providers could facilitate new. or augnent existing.
`distribution channels for better timed-release of inventory. The transactional data from the electronic distribution
`
`system could be used to obtain information regarding consumer buying patterns as well as to provide immediate
`feedback on electronic marketing programs and promotions.
`In order to meet these goals, a need exists for digital
`content providers to use an electronic distribution model to make digital content available to a wide range of users
`and businesses while ensuring protection and metering of digital assets.
`
`Other commercially available electronic distribution systetrts for digital content. such as real audio. A23
`
`from AT&T. Liquid Audio Pro fi'om Liquid Audio Pro Corp.. City Music Network from Audio Soft and others
`
`ofier transmission ofdlgttal data over secured and unsecured electronic networks. The use of secured electronic
`
`networks greatly reduces the requirement of digital content providers of distributing digital to a wide audience.
`
`The use of unsecured networks such as the Internet and Web allows the digital content to arrive to an end- user
`
`securely such as through the use of encryption. However. once the encrypted digital content is do-encrypted on the
`
`end-user's machine.
`
`the digital content
`
`is readily available to the end-user for unauthorized re-distribution.
`
`Therefore a need exists for a secure digital content electronic distribution system that provides protection of digital
`
`assets and ensures that the Content Providcr(s)‘ rights are protected even after the digital content is delivered to
`
`consumers and businesses. A need thus exists for rights management
`
`to allow for secure delivery. licensing
`
`authorization. and control of the usage of digital assets.
`
`Another reason owners of digital content have been slow to embrace electronic distribution is their desire
`
`to maintain and foster existing channels of distribution. Most content owners sell through retailers.
`
`In the music
`
`market these U.S. retailers include Tower Records. Peaches, Blockbuster. Circuit City and others. Many of these
`
`retailers have Web sites that allow Internet users to makes selections over the Internet and have selections mailed
`
`to the end-user. Example music Web sites include @tower, Music Boulevard and Columbia House. The use of
`
`electronic distribution can remove the ability of the retail stores from differentiating themselves from each other
`
`and differentiate themselves from the content owners, especially on the Web. Therefore a need exists to provide
`
`retailers of electronic content such as pictures, games. music. programs and videos a way to differentiate
`
`themselves from each other and the content owners when selling music through electronic distribution.
`
`Content owners prepare their digital content for electronic distribution through distribution sites such as
`
`electronic stores.
`
`Electronic stores on the Internet. or through other online services. want
`
`to differentiate
`
`themselves from each other by their product offerings and product promotions. A traditional store. i.e.
`
`— the
`
`non—electronic. non-online analogs to electronic stores - use product promotions. product sales, product samples,
`
`liberal
`
`return policies
`
`and other promotional programs to differentiate themselves from their competitors.
`
`However, in the online world where the content providers impose usage conditions on the digital content. the
`
`ability of electronic stores to differentiate themselves may be severely limited. Moreover. even if the usage
`
`conditions can be changed, electronic stores are faced with the difficult task of processing the metadata associated

`
`with the digital content from the content providers to promote and sell products electronically. Electronic stores
`need to manage several requirements when processing the metadata. First, the electronic store is required to
`
`receive the mctadata associated with the digital content from the content providers. Many times. parts of this
`
`rrtetadata may be sent encrypted, so the content provider must create a mechanism to decrypt the encrypted content.
`
`Second, the electronic store may wish to preview meladala from the content provider either before the content is
`
`received from the content provider or after the content is received by the electronic store. in order to assist with
`
`product marketing, product positioning and other promotional considerations for the content. Third. the electronic
`
`store is required to extract certain metadata used for promotional materials such as graphics and artist information.
`
`Often. this promotional material
`
`is used directly by the electronic store in its online promotions. Fourth. the
`
`electronic stores may wish to differentiate themselves from one another by modifying some of the permitted usage
`
`conditions to create different ofierings of the digital content. Fiflh. the electronic store may have to insert or alter
`
`certain address. such as URLs. in the metadata to direct payment reconciliation to an account reconciliation house
`
`automatically by the purchaser without the need to go through the electronic store for payment clearance. Sixth,
`
`the electronic store may need to create licenses for the permitted use of the copyrighted digital content that match
`
`usage conditions. For example. the license may grant the permission to make a limited number of copies of the
`
`digital content. A license is needed to roll act the terms and conditions of the permission granted.
`
`In light of all these requirements. to process the metadata related to the digital content, many electronic
`
`stores write customized software programs to handle these requirements. The time. cost and testing needed to
`
`create these customized software programs can be large. Accordingly. a need exists to provide a solution to these
`
`10
`
`15
`
`20
`
`requirements.
`
`Still, another reason owners of digital content have been slow to embrace electronic distribution is the
`
`difficulty in preparing content for electronic distribution. Today, many providers of content have thousands or
`
`even tens of thousands of titles in their portfolio. In a music example. it is not unusual for a content owner to have
`
`a single master sound recording available on several difi‘erent
`
`formats simultaneously (e.g. CD.
`
`tape and
`
`MiniDisc}.
`
`In addition. a single format can have a master sound recording re-mastered or re-rrtixed for a specific
`
`distribution channel. As an example. the mixing for broadcast radio may be different than the mixing for a dance
`
`club sound track. which may be different than a generally available consumer CD.
`
`lnvcrttorying and keeping track
`
`of these different mixes can be burdensome. Moreover, many owners of master recordings often times re-issue old
`
`recording in various subsequent collections. such as “The Best Of“. or
`
`in compilations for musical sound tracks
`
`to movies and other collections or compilations. As more content is offered digitally. the need to re-mix and
`
`encode the content for electronic distribution grows. Many times providers need to use old recording formats as
`
`guides to select the correct master sound recordings and have these sound recordings reprocessed and encoded for
`
`release for electronic distribution. This may be especially true for content providers that wish to use their old
`
`formats to assist them in re-— releasing the old sound recording for electronic distribution. Providers will
`
`look
`
`through databases to match up titles. artists and sound recordings to set the encoding parameters. This process of‘
`
`manually searching databases for recording portfolios is not without its shortcomings. One shortcoming is the
`
`25
`
`30
`
`35
`
`
`
`5
`
`
`
`W0 00!l}89D9
`
`*
`

`
`PCTz‘US99!l 8383
`
`need to have an operator manually search a database and set the processing parameters appropriately. Another
`shortcoming is the possibility of operator transcription error in selecting data front a database. Accordingly. a need
`exists to provide content providers a method to automatically retrieve associated data and master recordings for
`content such as audio.
`
`Content owners prepare their digital content for electronic. distribution through a process known as
`encoding. Encoding involves taking the content, digitizing it. if the content is presented in an analog format. and
`
`compressing it. The process of compressing allows the digital content to he transferred over networks and stored
`
`on recordable medium more efficiently because the amount of data transmitted or stored is reduced. However,
`
`compression is not without its shortcomings. Most compression involves the loss of some information. and is
`
`called lossy compression. Content providers must make decisions on what compression algorithm to use and the
`
`compression level required.
`
`For example.
`
`in music,
`
`the digital content or song may have very different
`
`characteristics depending on the genre of the music. The compression algorithm and compression level selected
`
`for one genre may not be the optimal choice for another genre of music. Content providers may find certain
`
`combinations of compression algorithms and compression levels work very well
`
`for one genre of music. say
`
`classical. but provide unsatisfactory results for another genre of music such as heavy metal. Moreover. audio
`
`engineers must often equalize the music. perform dynamic range adjustments and ptznform other preprocessing and
`
`processing settings to ensure the genre of music encoded produces the desired results. The requirement to always
`
`have to manually set these encoding parameters such as setting the equalization levels and the dynamic range
`
`settings for each digital content can be burdensome. Returning to the music example. a content provider for music
`
`with a collection covering a variety of musical genre would have to manually seltxt for each song or set of songs to
`
`be encoded. the desired combination of encoding parameters. Accordingly, a need exists to overcome the need for
`
`manually selection of process parameters for encoding.
`
`The process to compress content can require a large amount of dedicated computational resources.
`
`especially for larger content items such as fi.tll-length feature movies. Providers of compression algorithms offer
`
`various tradeofis and advantages associated with their compression techniques. These tradeoffs include: the
`
`amount of time and computational resources needed to compress the content; the amount of compression achieved
`
`from the original content; the desired bit rate for playback; the performance quality of the comprmsed content; and
`
`other factors. Using an encoding program which take as input a multimedia file and generate an encoded output
`
`file with no interim indication of progess or status is a problem. Moreover.
`
`in many circumstances, other
`
`programs are used to call or to manage an encoding program with no interim indication of progress. This leaves
`
`the calling application with no way to gauge the amount of content that has been encoded as a percentage of the
`
`entire selection of designated to be encoded.
`
`In circumstances where the calling program is trying to schedule
`
`several different programs to run at once this can be a problem. Furthermore, this can be especially burdensome in
`
`cases where batches of content have been selected for encoding and the content provider wants to determine the
`
`progress of the encoding process. Accordingly. a need exists to overcome these problems.

`
`Yet, still another reason digital content providers have been slow to adopt electronic distribution for their
`
`content is lack of standards for creating digital players on end-user devices for electronically delivered content.
`
`Content providers. electronic stores. or others in the electronic distribution chain may want to offer customized
`
`players on a variety of devices such as PCS. set-top boxes. hand-held devices and more. A set of tools that can
`
`handle the decryption of the digital content ina tamper resistant environment. that is. an environment to deter the
`
`unauthorized access to the content during playing by a third party is needed. Moreover. a set of tools is needed to
`
`enable an end user to manage of a local library of digital content without allowing the end user to have access to
`
`the content for uses other than what was purchased.

`
`SUMMARY OF THE INVENTION
`
`It is an object of the present invention to remove the above-mentioned drawbacks and to provide a system
`
`for tracking usage of content data.. One embodirrtent of the present invention provides a system for tracking usage
`
`of digital content on user devices. Electronic stores coupled to a network sell licenses to play digital content data
`
`to users. Content players, which receive from the network the licensed content data. are used to play the licensed
`
`content data. Additionally. a logging site that is coupled to the network tracks the playing of the content data.
`
`In
`
`particular. the logging site receives play information from the network. and the play information includes the
`
`number of times that the content data has been played by the associated content player.
`
`A further embodiment of the present invention provides a method for tracking usage of digital content on
`
`user devices. According to the method. a license to play digital content data is sold to a user. and the licensed
`
`content data is transmitted to a content player for the user. Further, information is transmitted to a logging site
`
`whenever the content data is played by the content player or copied fiom the content player to an external medium

`SECURE DIGITAL CONTENT ELECTRONIC DISTRIBUTION SYSTEM
`

`
`A.
`
`System Overview
`
`The Secure Digital Content Electronic Distribution System is a technical platform that encompasses the
`
`technology, specifications, tools, and software needed for the secure delivery and rights management of Digital
`
`Content and digital content-related content to an end-user. client device. The End-User Device(s) include PCS. set
`
`top boxes (l’RDs), and Internet appliances. These devices may copy the content to external media or portable.
`
`consumer devices as permitted by the content proprietors. The term Digital Content or simply Content, refers to
`
`information and data stored in a digital format including: pictures. movies. videos, music, programs, multimedia
`
`and games.
`
`The technical platform specifies how Digital Content
`
`is prepared, securely distributed through
`
`point-to-point and broadcast irtfiastructttres (such as cable, Internet. satellite, and wireless) licensed to End-User
`
`Device-(5). and protected against unauthorized copying or playing.
`
`In addition. the architecture of the technical
`
`platform allows
`
`for
`
`the
`
`integration and migration of various
`
`technologies
`
`such as watermarking,
`
`eompressionfencoding, encryption. and other security algorithms as they evolve over time.
`
`The base components of the Secure Digital Content Electronic Distribution System are:
`
`(1) rights
`
`management for the protection of ownership rights of the content proprietor: (2)
`
`transaction metering for
`
`immediate and accurate compensation; and (3) an open and well-documented architecture that enables Content
`
`Provider(s} to prepare content and permit its secure delivery over multiple network infrastructures for playback on
`
`20
`
`25
`
`30
`
`any standard cornpliartt player.

`
`Rights management in the Secure Digital Content Electronic Distribution System is implemented through
`a set of fiinetions distributed among the operating components of the system.
`Its primary fiinctions include:
`
`licensing authorization and control so that content is unlocked only by authorized intermediate or End-Userts) that
`
`have secured a license: and control and enforcement of content usage according to the conditions of purchase or
`
`licfinse. Such as permitted number of copies._ number of plays, and the time interval or term the license may be
`
`valid. A secondary function of rights management is to enable a means to identify the origin of unauthorized
`
`copies of convent to combat piracy.
`
`Licensing authorization and control are implemented through the use of a t’.‘1earinghouse(s) entity and
`
`Secure Container
`
`(SC)
`
`technology.
