High-Definition Content Protection (HDP) is a technology that allows PlayStation 4 owners to protect their games from unauthorized access. With HDCP, gamers can create a security system that encrypts their game data so that only they can access it. This prevents others from viewing or copying the data, ensuring that your game remains safe and private. HDCP is also required on all PlayStation 4 systems, so you can be sure that your games are protected even when you’re not connected to the network.
