Microsoft recently announced that starting June 1st, 2014, they would be using the Kinect camera along with facial recognition technology in order to help recognize users, and determine whether or not the person currently playing the game is an authorized user. If an unauthorized user is detected, a prompt will appear asking the user to purchase a Playpass for $9.99
When asked about how this new feature will affect multiplayer games or used games Microsoft statedEA is reportedly working with Microsoft to make this service available for their Origin service implementing similar features into standard webcams. EA however only plans on allowing user's to disconnect their camera up to 3 times before requiring you to purchase an additional license of the game. When asked for a comment, EA statedHackers are already trying to come up with work around to these procedures by feeding false images into the webcam, or placing photographs of people over the Kinect camera. In response to this, Microsoft is creating additional verification steps for users it detects might be trying to cheat the system. In your first offense, Microsoft will ask you to perform some action, including jogging in place, doing situps, or doing the "I'm a little teapot" dance.
Certain publishers, notably Ubisoft and EA have opted to force users who are suspected of cheating to undergo a lie detector test prior to playing their game. This test analyzes your heart rate, posture, tone of voice, and other aspects that have not been revealed in a series of questions in order to determine whether or not you're being completely honest about your ownership of the game.
