A Proposal of Privacy Management Architecture

Recent use of web services has spread over a wide variety of application areas. Users are requested to disclose private information for the use of web services. Such a disclosure is facing the risk of leaking private information. Privacy leakage is becoming one of the serious social problems. For the better use of web services, it is necessary to provide a reliable scheme for privacy management. There are many cases of private information leakage which are caused by user´s misuse or unintended disclosure. In order to prevent users from unnecessarily leaking of private information, the users will be asked to clearly define information disclosure criteria. This paper discusses a privacy management architecture to prevent users from unnecessary leaking of private information. We demonstrate a prototype implementation how the proposed architecture effectively works in the initial setting of web services.
