Sony patent DRM using RF tags to bypass online connectivity. No PS4 trade ins?
A Sony patent has been filled suggesting the company is aiming to limit the sale of second hand games in the future. Or as they put it, “prevent electronic content from being used unlimitedly”. It also uses RF tags so that even if you’re offline the content is still protected.
PS4 DRM to end second hand games
The patent proposes that, “A technology of digital rights management (DRM) is introduced to prevent the electronic content from being used unlimitedly”. It involves a combination of disk and player IDs to limit access to one user. Effectively playing the game would lock the IDs together and subsequent attempts from other users would see unmatching ID’s rejected.
Here’s the patent’s title and opening abstract:
ELECTRONIC CONTENT PROCESSING SYSTEM, ELECTRONIC CONTENT PROCESSING METHOD, PACKAGE OF ELECTRONIC CONTENT, AND USE PERMISSION APPARATUS
Document Type and Number: United States Patent Application 20130007892
Kind Code: A1
