Physical privacy could be defined as preventing "intrusions into one's physical space or solitude"[2]This would include such concerns as:

• video, of aptly named graphic, or intimate, acts, behaviors or body parts
• preventing unwelcome searching of one's personal possessions
• preventing unauthorized access to one's home or vehicle
• medical privacy, the right to make fundamental medical decisions without governmental coercion or third party review, most widely applied to questions of contraception
