Web services are gaining popularity and the growth has led to personal information of more and more users being shared with service providers. This has raised concerns about potential accidental or malicious unauthorized use of personal information of the users. This paper concentrates on how the users can be given a sense of safety and trust about service invocations. It also seeks to find the ways to ensure privacy in the heterogeneous and diverse environment of modern computing. This paper presents a privacy-enhanced personal information and identity Management architecture to protect web service users. The architecture proposed in the paper is called transparent privacy-enhanced Identity Management of Web Service (TPIM). TPIM is essentially an extension of SOAP specification. It provides a feeling of "Circle of trust" in personal information and helps in identity management during collaborations of various web services. According to the paper, TPIM protects the user's personal information and identity and enables them to reveal it only to the person the user trusts. Simply put, a user can use personal information on any web service and still maintain privacy in different user-managed security levels. This includes unconditional anonymity. The paper concludes that TPIM shall provide user friendly methods of managing digital identities and help protect privacy in the online world.
