World Wide Web Consortium Issues P3P 1.0 as a W3C
P3P gives people more control over use of personal information on the Web
16 April 2002 -- The World Wide Web Consortium (W3C)
has issued the Platform
for Privacy Preferences (P3P) 1.0 as a W3C Recommendation, representing
cross-industry agreement on an XML-based language for expressing Web site
privacy policies. Declaring P3P a W3C Recommendation indicates that it is a
stable document, contributes to Web interoperability, and has been reviewed by
the W3C Membership, who favor its widespread adoption. P3P was designed by a
Working Group composed of privacy advocates, Web technology leaders, data
protection commissioners, and global ecommerce companies.
"Web site privacy policies are good, but understanding privacy
policies is better," remarked Tim Berners-Lee, W3C Director. "P3P
serves as the keystone to resolving larger issues of both privacy and security
on the Web."
P3P Helps People Make Informed Choices
The Platform for Privacy Preferences Project (P3P) 1.0, developed by W3C,
provides a standard, simple, automated way for users to gain more control over
the use of personal information on Web sites they visit.
At its most basic level, P3P is a standardized set of multiple-choice
questions, covering all the major aspects of a Web site's privacy policies.
Taken together, the answers present a machine readable version of the site's
about its users. P3P-enabled Web sites make this information available in a
standard, machine-readable format.
P3P enabled browsers can "read" this snapshot automatically and
compare it to the consumer's own set of privacy preferences. P3P enhances user
control by putting privacy policies where users can find them, in a form users
can understand, and, most importantly, enables users to act on what they see.
"With P3P we are enabling the development of a whole new class of Web
tools and services that will help users protect their privacy while
streamlining ecommerce transactions," explained Daniel J. Weitzner, W3C
Technology and Society Domain Leader, "The fact that the Web now has a
standard language for describing privacy practices will enable a new level of
transparency in Web-based interactions. The added facility for dealing with
privacy issues will be especially important with mobile and other new forms of
P3P Results from International Cooperation
P3P is created through the consensus-based W3C Process. Participants in the
development of P3P represent leadership in industry, government, and research.

Many organizations have provided statements
of support, some are announcing implementations.
"International representation was key to providing a privacy
vocabulary that meets diverse needs and requirements," explained Rigo
Wenning, W3C Privacy Activity Lead. "The Working Group also benefitted
from the joint presence of industry, public authorities and academics. The
design of P3P takes into account the multitude of privacy frameworks all over
Next Steps for P3P Focus on Implementation
W3C's lists of P3P-enabled
Web sites and P3P
software continue to grow, including both plug-ins and browser-based
implementations, P3P policy generators, and a P3P
W3C's P3P Working Group
plans to continue to provide resources and assistance to implementers who wish
to make their sites P3P compliant. In addition to the P3P
homepage, other useful resources include p3ptoolbox.org
in cooperation with the Internet
Education Foundation, and the JRC
P3P demonstration and research platform. W3C continues to maintain
discussion fora for implementers and those interested in P3P.
