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.
