`Introduction
`
`Whatever you cannot understand you cannot possess.
`- Goethe
`
`Every revolution in technology and business brings with it a host
`of new words, abbreviations, and acronyms. Electronic commerce is
`spawning more than its share(cid:151)digital cash, electronic catalog,
`Internet presence, network payment system(cid:151)to name a few.
`Managers are finding they need to learn the nomenclatures of the
`Internet, electronic data interchange (EDT), electronic funds transfer
`(EFT), bank card operations, and many other fields covered in this
`book. Driven most recently by the growth of the World Wide Web,
`electronic commerce is poised to change the business landscape
`permanently.
`This book is for anyone working to understand electronic
`commerce and looking for opportunities to profit from it. The
`definitions are based on usage in both general and technical
`sources(cid:151)books, seminar materials, government publications,
`magazines, over two hundred World Wide Web sites and FTP servers,
`and the author’s years of experience in commerce and data
`communications. The intent has been to make each term
`understandable to anyone with modest computer literacy. ’Where
`appropriate, specific products and companies are identified.
`Cryptography, long the purview of government agencies and the
`military, turns out to be the bedrock on which many new ways of
`doing business over public networks are founded. Although many
`cryptographic terms are defined in this book, the relatively
`sophisticated math behind RSA and other algorithms is not described
`in detail. There are several excellent books on network security and
`on cryptography which can provide in-depth information.
`Where words or phrases important to a definition are themselves
`defined elsewhere they are printed in SMALL CAPITAL LETTERS. Plural
`
`ix
`
`SAP 1013
`IPR2014-00414
`Page 9 of 124
`
`
`
`words in capitals (e.g. MICROPAYMENTS) are usually defined in the
`singular form. ’Where two or more words are in capitals (e.g. WEB
`BROWSER) the words will sometimes be defined separately rather as a
`single phrase.
`The dictionary is designed to remain a fundamental resource in
`the development of electronic commerce. New words and other
`updates to this book will be published on the Electronic Commerce
`Dictionary Web site at http://www.haynes.com/haynes . Readers are
`encouraged to check this site for new information periodically.

`caller ID services Services provided by telephone companies that
`enhance SECURITY by providing the phone number of the calling
`party over the phone line to the receiving party before the call is
`picked up. Variations of the services are Caller Number Delivery
`(CND), and Calling Line Identification. Services are available
`only where permitted by local regulation. The major drawback to
`the service is that the information is not passed between phone
`carriers and cannot be used in granting ACCESS to a computer when
`users call through a phone carrier other than that serving the
`computer itself.

`action sets to more than one computer.

`where the vendor cannot check that the buyer has physical pos-
`session of the card itself.
`CARl A system of making CREDIT CARD purchases through the
`Internet without sending credit card numbers over the network.

`along with the buyer’s encrypted telephone number and a
`preferred time to call. When contacted, the customer enters into
`the phone keypad the virtual credit card number, a PIN, and the
`credit card number and expiration date of a credit card. CART
`combines this with the order information from the merchant and
`formats a transaction file.
