Can software be protected from piracy?
Why does it seem so easy to pirate today?
It just seems a little hard to believe that with all of our technological advances and the billions of dollars spent on engineering the most unbelievable and mind-blowing software, we still have no other means of protecting against piracy than a "serial number/activation key." I'm sure a ton of money, maybe even billions, went into creating Windows 7 or Office and even Snow Leopard, yet I can get it for free in less than 20 minutes. Same for all of Adobe's products, which are probably the easiest.
Can there exist a fool-proof and hack-proof method of protecting your software against piracy? If not realistically, could it be theoretically possible? Or no matter what mechanisms these companies deploy, can hackers always find a way around it?
