Web user profiles are widely applied to complete the high-quality website design and the personalized web services. One issue in this technology is the study of contradiction between the collection of personal data and the protection of user privacy. In order to alleviate the contradiction, this paper provides a new profiling approach, namely non-violative user profiling, which integrates the non-violative strategy and Markov user model ideas. It can extract more exact information automatically with the participation of web users. It has been implemented in our experimental website to identify the design defects and validate the effectiveness of the proposed approach.
