摘要

An attribute information providing device (510) manages attribute information as information relating to a user and provides the information to another device. An access information management device (530) manages first access information for accessing the attribute information providing device (510) by an attribute information obtaining device (520). An access information substitutional management device (540) manages second access information for accessing the access information management device (530) by the attribute information obtaining device (520). The attribute information obtaining device (520) obtains the attribute information from the attribute information providing device (510) on the basis of the second access information obtained from the access information substitutional management device (540) and the first access information obtained from the access information management device (530).
