Sony might have put the kibosh on the PS4 blocking used games, but the company still intends to protect its new system from piracy. And it seems to have figured out a way to do that - a recently published patent details a method of determining if a piece of software is legitimate or not.
The system works by comparing load times of a particular piece of software against a benchmark. If the software breaches a certain comparison threshold, then the technology will be able to determine your copy as pirated.
Titled "Benchmark Measurement for Legitimate Duplication Validation
", the patent was filed in 2011 but was published on February 21 2013. Just a day after the PS4's official announcement. Coincidence?
