Well, dummy data wouldn't do much. I didn't mean 1 file missing, I meant 1 digit of data...all the way down to the actual program code itself. One thing changes, boom, it's invalid. It parses the file, takes note of every 1 and 0, then signs it to perfectly match the pattern.

An engine to generate a signature is exactly what we'd need...only problem is that the only one in existance is in Sony's possession.
