Welcome to the Efficient E-Commerce Architectures Project
Economical Trust and Assurance for E-Commerce
Electronic commerce (e-commerce) is a broad, interdisciplinary field addressing the
automation of business transactions. E-commerce improves the efficiency of current
business practices and fosters new, productive approaches. Several observations can be
made:
Initial successes in e-commerce have occurred among large organizations that built
complex, closed-membership systems. However, open, interoperable e-commerce is
equally important, since half of the US economy is conducted by small businesses that
cannot afford expensive services. Increasingly, e-commerce involves globally spanning, public network access via the
World Wide Web. Web economies and flexibilities are hard to ignore. For example,
customer-to-customer Web auctions could not exist without Internets powerful
aggregating of parties across great distances and populations.
Trust is fundamental in pursuing commercial objectives on the Internet.
Web-based assurance should dispel wariness among trading parties who do not know eachother. We thus have participated with the Financial Systems Technology Consortium
(www.fstc.org) in its FAST (Financial Agent Secure Transaction) project. FAST addresses
e-commerce participants with concerns about
Valid identities for other Web parties.
Characteristics being claimed, promised or contracted for (examples are payment
guarantee, shipping reliability or rights of product use).
Privacy for personal data and business marketing information.
A 186-page Phase I FAST report is complete and will be available to the public in early
2001. A sketch of the FAST approach appears below.

who have no common basis for trust. Parties never actually meet. No one knows directly who the others are,
nor exactly what reputation each has. (An important attribute of a party might be sufficient balance,
authority to commit a company to a transaction or offerers true Web address(URL).) This problem of
identity and verification of attributes is not new: letters of introduction and of credit are conventional
instruments for this. However, the timeframe for authentication must be shortened for e-commerce.
Authentication is now needed in seconds. The advent of electronic networks makes possible trust
frameworks that are faster, more comprehensive and more secure than paper documents.
Although individuals, merchants and other business entities may have no convenient way to authenticate eachother, almost all have relationships with banks, credit unions and other agents of trust. These agents and
institutions could provide authentication services on behalf of the their customers to establish commercial
trust with more distant partners. The agents of trust link together via a closed electronic link trust (depicted
below). Business parties 1 and 2 correspond via open Internet service. Each party has a secure link to an
agent. This link may be sophisticated (encryption) or plain (browser with password). In any case, party 1
asks agent 1 to confirm to party 2 (via agent 2, whom party 1 is unaware) something that party 1 cannot
establish alone. The customer can remain anonymous (as can the merchant, but most want their name
known).
