The Platform for Privacy Preferences — An overview

Appendix 2 — P3P Data Categories

(From http://www.w3.org/TR/1998/WD-P3P-harmonization#DataCategories as at 9 April 1998)

0. Physical Contact Information

Information that allows an individual to be contacted or located in the physical world — such as phone number or address.

1. Online Contact Information

Information that allows an individual to be contacted or located on the Internet — such as email. Often, this information is independent of the specific computer used to access the network. (See Computer Information)

2. Unique Identifiers

Non-financial identifiers issued for purposes of consistently identifying the individual — such as SSN or Web site IDs.

3. Financial Account Identifiers

Identifiers that tie an individual to a financial instrument, account, or payment system — such as a credit card or bank account number.

4. Computer Information

Information about the computer system that the individual is using to access the network — such as the IP number, domain name, browser type or operating system.

5. Navigation and Click-stream Data

Data passively generated by browsing the Web site — such as which pages are visited, and how long users stay on each page.

6. Transaction Data

Data actively generated from or reflecting explicit interactions with a service provider through its site — such as queries to a search engine, logs of account activity, or purchases made on the Web.

7. Demographic and Socio-economic Data

Data about an individual’s characteristics — such as gender, age, and income.

8. Preference Data

Data about an individual’s likes and dislikes — such as favourite colour or musical tastes.

9. Content

The words and expressions contained in the body of a communication — such as the text of email, bulletin board postings, or chat room communications.
