W3C P3P

21 June 2000 Platform for Privacy Preferences (P3P) Project Interop Report

On June 21, 2000, about 100 people gathered at the AT&T building at 32 Avenue of the Americas in New York to witness the first public tests and demonstrations of the Platform for Privacy Preferences Project (P3P). W3C's public "interoperability session" gave companies the opportunity to unveil new prototypes, to test them with other P3P services, and to provide input into the P3P design process. The prototypes are early versions of P3P-compliant tools expected to be offered to end users in the coming year. [See Interop agenda, interop mailing list archive]

Presentations and Demos

Daniel Weitzner (W3C), Harriet Pearson (IBM), Deirdre Mulligan (CDT), and Lorrie Cranor (AT&T) gave opening remarks, including background and an overview of P3P [PowerPoint slides]. Implementers then demoed four P3P user agent implementations and two P3P policy generators. The demos were followed by a question and answer period. Attendees were then invited to try the presented demos as well as some additional demos that were setup on computers around the room.

User Agent Demos

Ron Perry from IDcide demoed a version of the IDcide Privacy Companion augmented with P3P. The Privacy Companion is a browser extension that allows users to find out whether a site is using cookies, including third party cookies, and also to block all cookies and/or third-party cookies. With P3P added, users can customize their settings to only block cookies from sites that do not match their privacy preferences. [screen shots of IDcide Privacy Companion]

Noboru Shimizu from the Electronic Network Consortium (ENC) demoed the Privacy Information Management System. The browser component uses a proxy server that fetches P3P policies and compares them with user preferences. The system also includes an authoring tool that can generate P3P policies and a site bureau where Web sites can register their privacy policies.

Chris McLaren and David Zimmerman from YOUpowered demoed a version of Orby Privacy Plus augmented with P3P. Orby allows users to accept or deny cookies while surfing, automatically fill out forms, and determine how well a site matches their privacy preferences. The Orby Trust Meter displays a trust rating determined by analyzing a site's P3P policy. Users can click to get more detailed information about the site's policy and the factors that went into determining the rating. YOUpowered has also developed a tool for authoring P3P policies.

Greg Hampson from Microsoft demoed prototype P3P user agent software developed jointly with AT&T. This user agent is implemented as a browser helper object for Internet Explorer. When users install this software, it adds a privacy button to the top of their browser window. Clicking on this button brings up a window where users can set their privacy preferences, check how well a site's P3P policy matches their preferences, or view a site's privacy policy in P3P or human-readable format.

Policy Generator Demos

John Newman from PrivacyBot.com demoed the PrivacyBot system for generating privacy policies in both human-readable and P3P format. The PrivacyBot system is accessed via a web browser and does not require users to download any additional software. Users fill out a series of online questionnaires in order to create their privacy policies. The software is already available to customers.

Martin Presler-Marshall from IBM demoed a P3P Policy Editor. This is a visual tool for creating P3P policies. Users can use a mouse to drag various policy elements into place and view the results in both XML and English. The tool includes extensive documentation. Beta software is available for download free of charge.

P3P Compliant Web Sites

Over a dozen Web sites were made P3P compliant in time for the event including:

Tatiana Gau from AOL, Barbara Lawler from Hewlett-Packard, and Mel Peterson from Procter & Gamble spoke briefly about the process of making their sites P3P compliant.

These web sites were tested with the W3C P3P Validator and the demoed user agents.

Feedback

The P3P Specification working group held an open meeting after lunch. The group discussed each of the demos and compiled a list of issues that need further discussion.

Next Steps

The P3P Specification Working Group will discuss the issues raised at the Interop as well as other issues that have been raised since the May 10 working draft was issued. The group will try to resolve these issues and release a new working draft in August. This draft is expected to have a two-week public review period before the group begins the process of advancing towards a W3C recommendation.
