ABSTRACT:
A piracy protection system incorporates tamper detection capabilities into a protected copy of an application by disassembling a statically linked binary of the application, modifying some of the instructions in the application, and then rewriting all of the modified and unmodified instructions to a new executable file, a protected copy. The piracy protection system comprises an offline tamper detection technique in which the software itself detects the tampering and causes the program to fail, therefore protecting itself from malicious attacks. The system further comprises a dynamic software-watermarking process that incorporates code obfuscation to prevent reverse engineering.
