Abstract: A method and implementing computer system are provided in which selected information is embedded within computer program structures without requiring separate bit strings. In an exemplary embodiment, the embedded selected information includes an identification of a licensed user together with a serial number of the associated licensed program. That information is converted into a binary representation, and a transfer function is used to embed the binary representation into the structure of the licensed program. In the example, when a licensed program is compiled, linked and downloaded over an interconnection network, the order or sequence of the modules of the licensed program is arranged in a manner to correspond to the embedded selected information. The embedded information can then be extracted from the program by analysis of the organization of the modules comprising the program.
