body: I'm a little confused as to how the law is applied to this question. On the one hand, the right to privacy only extends to your home or immediate surroundings in places like public restrooms (the stall). Therefore, if you are out in public you can be recorded (e.g., health and fitness centers that have CCTVs). However, on YouTube, I continue to see people being asked if they can be in a video. In some of those videos, faces are even blurred out. What are your legal rights in these situations? Is consent required? 
  
  
  My question is not a duplicate because it asks the additional question: If consent is granted can it be revoked later?
