Business protocols are becoming a necessary part of Web services description. The work presented in investigates mechanisms for analyzing the compatibility and the substitution (i.e., replace ability) of Web services based on their functional properties. In this paper, the authors focus on the replace ability analysis. Whether a service can replace another depends not only on their functional properties but also on non functional requirements (e.g., privacy policies). They propose a privacy-aware protocol replace ability approach to extend the work presented in by privacy properties. They introduce a rule-based privacy model and they extend business protocols, leading to what they call private business protocols.
