The work deals with copyright protection for software written in object-oriented language (such as C++ and Java). The model used allows to insert watermarks on three "orthogonal" levels. For the first level, watermarks are injected into objects. The second level watermarking is used to select proper variants of the source code. The third level uses transition function that can be used to generate copies with different functionalities. Generic watermarking schemes were presented and their security discussed.
