Abstract: In the Web services composition, users privacy protection has been received widespread attention. When the requirement for users privacy data by one or more member services in the service composition is beyond the range of users willing to give, Web services composition need to be adjusted to ensure that the expose of privacy data is meeting the demand of the users. In this paper, we propose a new method of service evolution, which is based on the users privacy requirements. The key to this method is by controlling the scope of privacy datas references to achieve the purpose of reducing the risk of privacy exposure. Finally, through a travel agency case study, the feasibility of the proposed evolutionary approach is verified.
