The privacy chain

After a couple days soaking in privacy issues I'm starting to break everything into a three-part chain: identification, information and actions. (Appropriately enough for this conference, these these are fairly well associated with computers, privacy and freedom respectively.)

1. Identification: ability to identify an individual person or class of person. Includes face recognition, mandatory ID cards, DNA, iris scanners, retinal scanners, thumbprint, spyware, phone-home DRM, RFID chips in your clothing and other "Things That Fink," etc., as well as obvious things like racial profiling and having someone sign their name.
2. Information/Databases: access to information about those people or class of people. Medical, criminal, financial, your race/culture/religion, consumer preference data, where you've been, who you know, who you talk to, what you say...
3. Actions: what people with access to this information do. Some are good for the identified person or society (completing financial transactions, stop crime & terrorism, etc.). Many are bad, including police harassment of a particular race or religion, suppression of political dissent and travel of political activists, identity theft, scam games, red-lining, employment and insurance discrimination, price differentiation, loss of social reputation, and coercive advertising.

Many people have just a visceral negative reaction to someone knowing too much about them, but the consequences are mostly in part 3 — that's where you get stung. That said, sometimes the best way to stop something bad happening in step 3 is to stop steps 1 or 2 from happening, and often you never even find out that you didn't get a loan or a job due to a privacy violation.
