TRUST MANAGEMENT METHOD AND SYSTEM OF ID MANAGEMENT APPARATUS FOR USER CENTRIC IDENTITY MANAGEMENT

摘要

A method and a system for managing reliability of an ID management apparatus for user centric identity management are provided to precisely manage reliability since the reliability is evaluated according to types of the provided information, and to prevent damage caused by a harmful or incorrect ID management apparatus. A method for managing reliability of an ID management apparatus for user centric identity management comprises the following several steps. A service providing apparatus is connected to the ID management apparatus selected by the user from among plural ID management apparatuses, and ID information of the user is provided(S2100). The service providing apparatus provides a service to the user based on the provided ID information, and votes whether to trust the ID management apparatus by performing a post evaluation on the ID information(S2200). The reliability management apparatus computes a result of the voting on the reliability of each ID management apparatus received from a plurality of service providing apparatuses, and grants the reliability value to each ID management apparatus(S2300). When determining whether to trust the ID management apparatus, the service providing apparatus receives the information on reliability of particular ID information of a particular ID management apparatus from the reliability management apparatus, and determines whether to trust the ID management apparatus by comparing the reliability value with a predetermined standard value(S2400).
