SOAP to provide connectivity and interoperability between companies. Microsoft
Computer Dictionary, Fifth Edition, 564 (2002). We thus understand that a “web
service” could be any service that is conducted on the web, including the sale of
goods over the World Wide Web as described by Robinson at col. 6, ll. 56-58.
Robinson discloses creating the transaction record based upon details of a
completed transaction (Robinson, col. 4, ll. 25-33).
Robinson discloses sending the transaction record to a computer that
digitally signs (Robinson, col. 5, ll. 37-38) and encrypts the record (Robinson, col.
5, ll. 11-20).
Robinson discloses forming a digital receipt comprising the encrypted
transaction record (Robinson, col. 5, ll. 66-67, col.6, ll. 1-5).
Robinson discloses configuring the digital receipt page (step 118) on the
internet e.g., a web page, to enable display in a Web page (steps 124,125)
(Robinson, col. 6 ll. 23-36); and returning the digital receipt to at least one party
e.g., the merchant, to the completed transaction.
Robinson discloses using public key infrastructure (PKI) as part of the
receipt encryption process (Robinson, col. 5, ll. 40-52, col. 8, ll. 1-17).
Robinson discloses that although the merchant is in control of the computer
98 responsible for generating the digital receipt through exclusive access using a
personal secret key (Robinson, col. 5 ll. 42-50), the customer, rather than the
merchant, may present the digital receipt to the receipt generating computer 98
using the merchant’s key (Robinson, col. 5, ll. 46-50) to retrieve the transaction
data but cannot alter the data (Robinson, col. 8, ll. 38-45).
