In the filming of a flick. Producers do not require the consent of bystanders if they are not the main focus of the clip. For example, do you think hundreds of people signed permission slips for an actor being filmed in a sidewalk cafe?
Thus, 1. It's like your PC, expect all there is recorded somewhere in cyberspace. 2. When in public, act as if you're being recorded. 3. "Smile, you're on Candid Camera" :)
