Sony Suggested Simple DRM

Sony has recently come up with an interesting way to detect pirated software which it believes is simple enough to solve a lot of problems with DRM. As you know, DRM systems are normally complicated, easy to break and often punish legitimate users.


According to application 20130047267, published in the Patent and Trademark Office of the United States last month, gadgets using this technology can identify whether a copy of the game is legal based on the amount of time it takes to load into the device. Indeed, it’s very simple idea: the matter is that it would be difficult for pirates to get cracked software to be the same size as the original. In addition, the time factor also helps figure out whether the content is illegally transferred or pirated to another, unauthorized media type. Finally, it makes it harder for pirates to reverse engineer such technology and bypass the protections.

Theoretically, a gadget will have a threshold of load time for the content purchased legally. In case the media fails to pass the validation in terms of load time, the user would be unable to access the content, according to Sony’s new application.

However, there are always things that might go wrong. For instance, drives can be faster, and some games can be sped up by replacing a PlayStation’s hard drive with a faster solid state drive. According to the patent, this problem could be solved by encoding the DRM with times for each type of drive, which would check it against a benchmark load time for that media type. This comparison will be used to detect whether the title may have been illegitimately transferred or pirated to “another, unauthorized media type”. Apparently, much of the success of this idea would depend on whether the company is able to keep a hardware database updated.

Still, harder to factor in is the fact that damaged Blu-ray disks normally show slower loading times. The matter is that software might not authenticate as the disk loaded slower due to a scratch on its surface. Then, as you know, any disk-reading laser degrades over time, and this would also lead to slower read speeds. In case Sony’s DRM factors in those sorts of hardware problems, it won’t be any use as DRM…

Unsub avatarPrior to running the software it seems like they could just test the access time for whatever media it is running from, be it HDD, SSD, Blu-ray, USB storage, etc...then calculate load time and for scratches it seems like they could factor in read errors. It would take into account all the above factors. If it deemed something illegal it could give you the option to do a more thorough test of the media to account for bad sectors, etc...before disabling it.

trialNerror avatarKeep trying, Sony. It won't work.

Daewoo avatarAll the hacker need do is to remove the code for checking. That is how games were cracked in the past. Once the DRM was identified it would be removed, end of story.
