Abstract

A great deal of unauthorized copying of computer programs is taking place today. Thus, it would be very helpful to have some means of identifying the time origin of a program as a basis for halting such unauthorized copying. One way of accomplishing this would be to secretly embed a predetermined and unique data pattern or constant followed by message text in the program itself. The message text, if desired, could be broken up and distributed throughout the program code to make its detection even more difficult. Further, the constant could be embedded as one type of code, the message text as another. Thus, if the program were written in ASCII, the constant could be in EBCDIC code. Such alternative coding would prevent discovery of these identifiers by means of program dump.
