Computers simply make new threats possible and old threats more potent.
Privacy can mean:• Freedom from intrusion-being left alone.• Control of information about oneself.• Freedom from surveillance (followed, watched, eavesdropped
upon).

The Impact of Computer TechnologyInvisible Information Gathering
Examples:• Satellite surveillance.• Caller ID.• 800- or 900-number calls. Or Pizza Hut!• Web-tracking data; cookies. Peer-to-peer monitoring.
– Spyware such as Gator, BonziBUDDY, and Comet Cursor is often surreptitiously bundled with freeware and shareware software that users download from the Internet, and is commonly found in popular peer-to-peer programs, such as KaZaa, BearShare, AudioGalaxy, and others. In the most malicious cases, spyware can perform non-marketing operations, all hidden to the user, including data collection for industrial espionage purposes.

Protecting Privacy: Law and Regulation
Contrasting ViewsFree-market View
• The parties of a transaction are viewed as equal.• Truth in information gathering.• Strong reliance on contracts.• Freedom of speech and commerce.
Consumer-Protection View• The parties of a transaction are viewed differently.• More stringent consent requirements required by law.• Strong limitations on secondary uses of information required
by law.• Legal restrictions on consumer profiling.
