A patent by Sony has been published a couple of days ago, after being filed back in August of 2011. This patent is described to be able to detect pirated software through its load times. According to the patent, there will be a standard, or "acceptable threshold range", that will determine if the software is indeed pirated. When loaded, the software will be compared against the results with what is considered an acceptable threshold range. The software will be blocked if these load times are not within this specified range.
Being that it was filed last year and just released a couple of days ago, we can make an assumption that this is for the PS4, especially since it seemed to be released right after the system's announcement. Although, it was not specified for an individually named Sony product.
Neogaf also quoted the patent in sections below:
Using total benchmark load time:
Quote:
For example, if an authentic game title is distributed exclusively on BDs having a total benchmark load time of 45 seconds on a game console BD drive, the acceptable range of load times could be from 40 to 50 seconds. Thus, a total measured title load time of 4 seconds would be outside of the acceptable range of total load times for a legitimate media type.
Seek time:
Quote:
In another example, if an authentic game title is distributed exclusively on flash drives having a total benchmark load time of 5 seconds, the acceptable range of load times could be from 4 to 6 seconds. However, an illegitimate game product embodied on a hard disk may also have a total measured title load time of 5 seconds, which would be within the acceptable range of total load times for a legitimate media type. In this instance, each segment of the benchmark load time can be compared to the corresponding segment of the title load time to differentiate between the media types, again using threshold ranges. For example, a benchmark seek time associated with the flash drive could be 150 milliseconds, with an acceptable seek time range of 130 milliseconds to 170 milliseconds. Thus, a measured title seek time of 10 ms associated with the hard disk drive would be outside of the acceptable range of seek times for a legitimate media type.
Throughput:
Quote:
In another example, a benchmark throughput associated with loading the media product from a flash drive could be 30 megabytes per second, with an acceptable throughput range of 20 megabytes per second to 40 megabytes per second. Thus, a measured title throughput of 100 megabytes per second associated with loading the media on a hard disk drive would be outside of the acceptable range of throughput for a legitimate media type.
