Web services are middle-tier technologies used to access backend applications to perform various operations. Their usage has significantly increased in ecommerce applications since their introduction. Because of their wide usage, security in web services has become an important point of interest for many. User data provided by users during their transactions with online web services can be stolen and illegally used. Thus web service providers have started to strengthen security. This can lead to lack of user privacy. Privacy has received relatively less attention during the growth of information technology. User privacy management needs to be both from the user side and from web application side. User awareness about information security is the factor for user side privacy management. On the application side, the web applications must be compliant to privacy policies. In this paper, an approach is designed and implemented for a Privacy Policy Checker engine that automatically verifies and certifies a web service application based on the levels of overall privacy principle compliance and privacy statement compliance.
