ABSTRACT:
An implementation of a technology, described herein, for facilitating the protection computer-executable instructions, such as software. At least one implementation, described herein, may generate integrity signatures of multiple sets of computer-executable instructions based upon the output trace and/or an execution trace of such sets. With at least one implementation, described herein, a determination may be made about whether two or more of such sets are unaltered duplicates by comparing integrity signatures of such sets. This abstract itself is not intended to limit the scope of this patent. The scope of the present invention is pointed out in the appending claims.
