`ABSTRACT
`
`Disclosed is a method and apparatus of securely providing
`data to a user’s system. The data is encrypted so as to only
`be decryptable by a data decrypting key, the data decrypting
`key being encrypted using a ?rst public key, and the
`encrypted data being accessible to the user’s system, the
`method comprising the steps of: transferring the encrypted
`data decrypting key to a clearing house that possesses a ?rst
`private key, Which corresponds to the ?rst public key;
`decrypting the data decrypting key using the ?rst private
`key; re-encrypting the data decrypting key using a second
`public key; transferring the re-encrypted data decrypting key
`to the user’s system, the user’s system possessing a second
`private key, Which corresponds to the second public key; and
`decrypting the re-encrypted data decrypting key using the
`second private key.

`ELECTRONIC CONTENT DELIVERY
`SYSTEM
`
`CROSS-REFERENCE TO RELATED
`APPLICATIONS
`
`This non-provisional application claims subject matter
`that is technically related to the following applications that
`are commonly assigned herewith to International Business
`Machines (IBM).
`
`2
`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
`content on to tangible media, albeit, in many cases less than
`a dollar for a blank tape or recordable CD. However, in the
`case of electronic distribution, the tangible medium is no
`longer needed. The cost of the tangible medium is not a
`factor because content is distributed electronically. Asecond
`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 the
`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 rela-
`tively easy pirate and distribute unauthorized copies. With a
`couple of keystrokes, a pirate can send hundred 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 distribution system includes developing
`systems 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 pro-
`Vides 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 augment 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 mar-
`keting 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 avail-
`able to a wide range of users and businesses while ensuring
`protection and metering of digital assets.
`Other commercially available electronic distribution sys-
`tems for digital content, such as real audio, A2B from AT&T,
`Liquid Audio Pro Corp. from Liquid Audio Pro, City Music
`Network from Audio Soft and others offer transmission of
`
`digital 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
`de-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

`BACKGROUND OF THE INVENTION
`
`1. 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, com-
`puter 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 of the
`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
`

`content electronic distribution system that provides protec-
`tion of digital assets and ensures that the Content Provider
`(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, Cir-
`cuit City and others. Many of these retailers have Web sites
`that allow Internet users to makes selections over the Inter-
`
`10
`
`net 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
`
`15
`
`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.
`Further information on the background of protecting
`digital content can be found from the following three
`sources. “Music on the Internet and the Intellectual Property

`SUMMARY OF THE INVENTION
`
`Briefly, in accordance with the present invention, dis-
`closed is a method and apparatus of securely providing data
`to a user’s system. The data is encrypted so as to only be
`decryptable by a data decrypting key, the data decrypting
`key being encrypted using a first public key, and the
`encrypted data being accessible to the user’s system, the
`method comprising the steps of: transferring the encrypted
`data decrypting key to a clearing house that possesses a first
`private key, which corresponds to the first public key;
`decrypting the data decrypting key using the first private
`key; re-encrypting the data decrypting key using ia second
`public key; transferring the re-encrypted data decrypting key
`to the user’s system, the user’s system possessing a second
`private key, which corresponds to the second public key; and
`decrypting the re-encrypted data decrypting key using the
`second private key.
