Software protection is a hot topic these days. Apart from legal protection, there are some possibilities to protect the software technically. Code obfuscation is a solution to technically protect software against inspection of the code. There are already two known possibilities to apply obfuscation transformations on the sofware. In this paper, we propose a third possibility; applying transformations during the link phase of the sofware build process. As there is an overview of the whole program, there are more possibilities and less restrictions than when applying transformations at an earlier stage.
