Description languages for Web service composition deal specifically with the definition of the business process logic, and do not provide support for the specification of security aspects related to the Web services involved. This paper uses the WS-Policy standard, and the WS-BPEL and WSCDL languages to propose a model for verifying the compatibility of Quality of Protection Policies of the business process participants, avoiding many conflicts between policies incompatibilities during execution time. The model emphasizes a general policy for the composite process.
