Summary: 
When a user receives personal services from a service provider, the service can be of a higher quality if the user provides more personal information. However, the risk of privacy violation could increase. Therefore, this paper proposes a privacy preserving agent that realizes avoidance of unwanted information disclosure by controlling disclosable attributes according to the results from monitoring two elements: user background information of the provider and user community status. This is done before disclosing individual attributes corresponding to the privacy policy (required anonymity) by each user. The validity of the proposed methods was confirmed by a desk model.
