Method and system for the communication of assured reputation information

摘要

There is provided a method and system of processing electronic transactions involving three parties, normally remote from one another. A service requestor(SR) requests a good or service from a service provider(SP) on the condition that certain terms will be fulfilled indicating that the good or service is provided at a particular standard. The service provider registers with a reputation authority terms for the supply of a good or service. Independently the service requestor acquires from the reputation authority a public key for which the private key is kept by the reputation authority. The service requestor(30) requests the service provider(20) for a good or service according to certain terms and the request is sent to the reputation authority which compares registered terms with the requested terms and if compatible signs the transaction with the retained private key and sends the signed transaction back to the service requestor. The service requestor can be confident that the service provider terms in the signed transaction has been assured by the reputation authority.
