  2. Outline • Introduction • Demo • Architecture overview • Conclusion

  3. Introduction • Currently and more so in the future, users are asked to divulge increasingly specialized information in exchange for higher levels of services in the electronic market, e.g. credit card company. • On the other hand, people are becoming more cautious in providing the personal information on the Web because of many obvious side effects, e.g. spam. • In fact, exchanging private information has become one currency of e-commerce that greatly affects the online businesses.

  4. Introduction • But the customer may be willing to divulge a private fact if they are informed exactly what it buys – what new, better service is guaranteed to be provided based on communicating that specific fact. • We envision that, by providing a negotiating service that tells people what they will get in exchange for divulging personal information, the customers will be more willing and more comfortable to offer their private information.

  5. Introduction • This paper will give an implementation of negotiating service that is based on the assumption that the levels of services are governed by the business policies or conventions that can be expressed by rules. • This negotiating service is built under the Web Services architecture.

  6. Policy Examples and their rule format • An elite customer can get 5% discount on decent or better cars if his payment type is “silver”. discount(X,Y,'5%')←eliteCustomer(X), decentCarOrAbove(Y), paymentType(silver). • “Silver” payment type is pay by 2 year installments with financial assistance of less than $10000. paymentType(silver)←payBy(‘2yearInstallment’), financialAssistance(lessThan$10000). • “Silver” payment type is pay by 3 year installments with financial assistance of less than $7000. paymentType(silver)←payBy(‘3yearInstallment’), financialAssistance(lessThan$7000).

  7. “Silver” payment type is pay by 5 year installments without financial assistance. paymentType(silver)←payBy(‘5yearInstallment’), financialAssistance($0). • The preferred customer who is insurance affiliated automatically becomes an elite customer. eliteCustomer(X)←preferedCustomer(X), insuranceAffiliator(X). • The customer who is older than 60 is the senior customer. senior(X)←moreThan60YearsOld(X).

  8. The customer who buys car insurance in First Rate Co. is insurance affiliated. insuranceAffiliator(P)←driverLicenceNo(P, X), insuredAt(‘First Rate Co.’, X).

Architecture Overview • The network of business policies and facts: • The business policies and facts of an industry are usually stored and maintained distributedly among different organizations. • A grant of a service may involve the support of policies and facts from several places. • This involvement usually takes the form of outsource the proof of some subgoals to other business rule services.
