According to newly found information from SKFU Sony plans to implement serial keys on Blu-Ray discs on the PS3. Similar to the serial keys already found on PC games this would lock each disc to a maximum of five uses.
Each disc will also be locked to a specific serial key, meaning that both parts are required to play the game on your PS3. When you enter your serial key and corresponding disc it will send a signal to Sony telling them that your game is legitimate.
Draconian DRM such as key locks has been heavily scrutinized in computer gaming and its likely that going to a 5 use lock on all PS3 will increase piracy.
Choosing to follow through with these plans will then give more incentive for people to pirate games as the paying customers are treated like criminals, not even having control over their own software.PS3 Piracy at an end?,
