Remote data integrity checking is a crucial technology in web services. Recently many works focus on providing data dynamics and/or public verifiability to this type of protocols. The goal of the Web Services Activity is to build up a set of technologies in order to direct web services to their complete prospective. Web services are playing excellent role, without web services is not possible to run the www or internet. Day by day the web technologies are improving and it is extended to all the minor or major fields like research, educational, business, etc. Existing protocols can support both features with the help of a third party auditor. This becomes the major disadvantage because third party can misuse our private data. So we develop new mechanism for securing web services, we have to consider five essential areas such as communication level security, communication privacy, zparameter inspection, authentication and authorization. The proposed protocol supports public verifiability without help of a third party auditor. In addition, the proposed protocol does not leak any private information to third party verifiers and also provides security mechanism described above.
