Explanation:
As of this writing, the latest W3C working draft of P3P is P3P 1.0, 28 January, 2002 (www.w3.org/TR).
An excerpt of the W3C P3P Specification states P3P enables Web sites to express their privacy
practices in a standard format that can be retrieved automatically and interpreted easily by user
agents. P3P user agents will allow users to be informed of site practices (in both machine- and
human-readable formats) and to automate decision-making based on these practices when
appropriate. Thus users need not read the privacy policies at every site they visit. With P3, an
organization can post its privacy policy in machinereadable form (XML) on its Web site. This policy
statement includes: Who has access to collected information The type of information collected How
the information is used The legal entity making the privacy statement P3P also supports user agents
that allow a user to configure a P3P-enabled Web browser with the user’s privacy preferences. Then,
when the user attempts to access a Web site, the user agent compares the user’s stated preferences
with the privacy policy in machine-readable form at the Web site. Access will be granted if the
preferences match the policy. Otherwise, either access to the Web site will be blocked or a pop-up
window will appear notifying the user that he/she must change their privacy preferences. Usually,
this means that the user has to lower his/her privacy threshold. The other answers are distracters.
