Abstract—Privacy has been acknowledged to be a critical concern for many collaborative business environments. Recently, verifying whether Web services composition satisfies privacy requirement is a hot spot for privacy protection. However, little research focuses on behavioral privacy requirement. This paper proposes an approach based on model checking to verify the satisfiability of behavior-aware privacy requirements in services composition. Firstly, we extract LTL specification from the behavior constrains of privacy requirements. On the other side, the behavior of BPEL process is modeled by extended interface automata, which supports privacy semantics. Then it is transformed to Promela description, the input language of the model checker SPIN. Finally, we illustrate the verification of privacy requirements with SPIN.
