The paper illustrates a distributed framework based on service oriented architecture, on which a logical transparent steganographic layer is developed. In this approach the related works on steganography and its anatomy is semantically studied and broken down into some independent services which are allocated on a network infrastructure. According to the underlying service oriented architecture (SOA), these services are able to communicate to each other or the other system services through a common language to dynamically form the desired compositions. This structure not only distributes the overall load of the process, it also considers some important system attributes such as reusability, simplicity, outsourcing, maintainability, flexibility and availability. Because of the open structure of the system, varieties of steganography algorithms can be supported for varieties of secrets, according to an evaluation strategy which is also considered as a service on the network. To clarify the proposed approach, the related ADL model together with an example scenario is expressed.
