Software, hardware, and content industries lose millions every year because of piracy, intellectual property theft, cracked copyright mechanisms, tampered software, malware, and so on. The basic problem lies in the openness of the underlying architecture of today’s computing systems. With the right expertise and tools, anyone can gain control over software running on their devices. There will always be users who will attempt to analyze and break software protection mechanisms, out of personal gain or pure curiosity. Therefore, a robust and efficient software protection scheme is an absolute must for all modern software applications in virtually all business areas. It is a fundamental factor in ensuring long-term profitability in today’s distributed software markets.
