What is the difference, if any, between physical privacy and informational privacy?
These are two different kinds of privacy. Physical privacy stands for exclusion of intrusions into person's physical space on the level of all human senses. Whereas informational privacy refers to protection of data collection and sharing about one's self. The latter includes financial privacy (information about a person's financial transactions is guarded), political (secret voting), Internet (encryption tools and anonymizing services), and medical privacy (doctor-patient confidentiality).
