Reliability authorizing method, reliability authorizing device, and reliability authorizing system

摘要

A reliability authorizing device determines whether to authorize a service transfer based on reliability of a partner device or a partner user when one user of one device authenticates other user of other device to exchange the service between devices connected to a network. A partner-reliability collecting unit collects reliability of the partner device or the partner user. A partner-reliability providing unit provides the reliability of the partner device or the partner user collected by the partner-reliability collecting unit.
