Future of Privacy Forum comments on Firefox’s plans to implement a Do Not track feature in Firefox 4:
“Firefox is advancing the “Do Not Track” concept by providing a simpler and more effective way to opt-out of behavioral ads, but in a way that is likely to allow most ad networks to continue to deliver relevant ads. Businesses would be well advised to agree respect the preference expressed by users who select this new option, as it could be also useful for mobile users and for apps. This is a prime opportunity for a multi-stakeholder group, such as the Commerce Department has proposed, to work out details like whether the preference could also result in collection or retention of less data about privacy sensitive users.”
Mozilla’s discussions of its plans are spread over a series of blogs.

As so often is the case, Julia Angwin is the first media reporter to break the story. And props to Chris Soghoian for his long leadership on this issue.
Background Information
The amorphous concept but catchy terminology of Do Not Track (“DNT”) has dominated much of the public discussion about what should be done about online privacy in recent months. Much of this discussion has been unproductive, with some in industry suggesting that DNT would bring an end to ad- supported online content, and some privacy advocates viewing it as a silver bullet solution for online privacY. Very little constructive dialogue has occurred across stakeholder groups. Browser companies, online businesses and advocates have by and large formulated their views without collaboration.
In 2009, the Future of Privacy Forum, in cooperation with the Center for Democracy and Technology, launched an effort to improve the current cookie based opt-out mechanism offered by many online behavioral advertising companies. Aware of the fact that many opt-out cookies are deleted by consumers or their anti-spyware programs, we convened companies, trade groups, advocates and technologists for a number of discussions aimed at formulating a more reliable process for providing consumers with options to limit the web tracking taking place for behavioral advertising purposes. At the meeting, technologist Chris Soghoian made the case for a Do Not Track browser header that he had coded, but few were open to the idea at this time.
In December 2010, FPF responded to the FTC’s formal DNT proposal by convening a panel which included representatives from browser companies, consumer and privacy organizations, technologists, ad networks, supporters of a DNT browser header and policy groups. Although no consensus emerged, we were convinced that a properly tailored and practically designed DNT browser header proposal was feasible. At the panel we suggested that if companies treated an opt-out header like a more permanent version of a behavioral advertising opt-out cookie, consumers would gain a new privacy control that would be easy to use. And since ad networks and trade associations have already agreed to provide consumers with the ability to opt-out of behavioral ads with one click (via the Network Advertising opt-out pages or the new Digital Advertising Association opt-out page), the policy choice was one that had already been made.
As a result, we are delighted that Firefox has just announced that in the new version of its browser, consumers will have an option in the preferences panel of the browser that would enable a special Do Not Track browser HTTP header.
Ad Networks:
Servers that are sent this header should recognize that the consumer has indicated that they do not want their activity online used to tailor advertising to them across unrelated web sites. We hope that services that offer consumers a cookie based opt-out should treat consumers presenting the header in the same manner they treated consumers relaying an opt-out cookie. Since opt-out cookies are often deleted inadvertently by consumers, this header will provide greater stability and a more reliable means of recognizing consumer choices.
For users who present the header, we think that companies should recognize the header to indicate “no targeting” based on previous unrelated activity, whether tracked via cookies, device fingerprinting, local shared objects, or other identifiers. Such header shall not affect tailoring of advertising for a user based on inferences made about a user based on the presentation of browser information or activity during a consumers visit to a particular web site. Thus geo-targeting based on IP address or tailoring of ads based on a consumers previous visit to the same web site shall be permitted.
Consumers:
Consumers today can technically prevent tracking by using cookie settings or browser based options or third party browser plug-ins which limit the data that is shared by their browsing activity. But these options are unable to provide high degrees of nuance tha can distinguish between the various types of uses of data by sites. These tools either underblock, overblock or prevent the delivery of any third party content or ads. Although P3P in theory could provide greater nuance, the manner in which it has been implemented in browsers and the distinctions between types of data use it provides often don’t map easily to the prevalent business models in use. Many consumers who today take steps to block cookies are likely expressing their opposition to behavioral advertising. An opt-out/DNT header provides those consumers with a more nuanced opportunity to express their choice.
Government:
What data should not be collected when a consumer has selected the opt-out header? Just the behavioral tracking cookie? Any unique tracking cookie? Other data? The most productive way to reach consensus on a proposal such as this is to convene a multi-stakeholder group that can work through the necessary cooperation between browser companies, ad networks, consumer representatives, government and policy groups. No system requiring nuanced cooperation and technology development across business models and government policy will spring into existing without interactions which can address the concerns of the key stakeholders. We suggest that Firefox convene such a multi-stakeholder group, including representatives from the FTC, Commerce and international stakeholders, in a process much as the Department of Commerce has called for in its report.
Kudos to the Firefox team and good luck to Alex Fowler, Mozilla’s new global privacy and policy who has just come on board. And huge credit to Chris Soghoian (who coded the first proof of concept of a DNT header and Arvind Narayanan of www.donottrack.us) along with Sid Stamm and others of the Mozilla team. We look forward to working with you on advancing consumer trust online.

Over the past few weeks, the Future of Privacy Forum (FPF) has been taking an informal poll from many of its advisory board members, blog readers and Facebook fans to gauge their thoughts on the recent privacy reports released by the Federal Trade Commission (FTC) and Department of Commerce. The FTC report was entitled, “Protecting Consumer Privacy in an Era of Rapid Change: A Proposed Framework for Businesses and Policymakers,” while the Department of Commerce’s Internet Safety Task Force privacy Green Paper was entitled, “Commercial Data Privacy and Innovation in the Internet Economy: A Dynamic Policy Framework.”
As our readers know, both reports were released this past December and FPF began taking our privacy insiders’ thoughts over the past month. Among the highlights, a large majority of respondents believed consumers need to be better educated to protect personal information online, but they do not believe a “Do Not Track” measure will be passed in 2011. Below are some of the key results provided by the respondents, and what these reports may mean for the future of privacy:

Jules and Chris submitted the following letter to the editor to The New York Times:
To the Editor:
In “10 Ways to Get the Most Out of Technology” (Personal Tech column, Dec. 30), you highlight some great free consumer tools and online services.
But consumers should know that many “free” online services actually do come with a price, usually the cost of letting the service use the consumers’ data for advertising or marketing purposes.
For some that may be a fair trade, and others may be more cautious, but consumers should make an informed choice so they know what they are signing up for.
