Unlike do not track, which requires the cooperation of websites, Tracking Protection is a feature that users can use to enforce their privacy preferences without relying on websites to give them any respect at all. But fortunately, the Tracking Protection feature is something consumers can use right away. Until the details about do not track get ironed out, the new IE9 header is not at all useful to consumers. Or companies that contract with advertising networks and other service providers could include language in their contracts obligating all of their vendors to respect do not track. For example, if there was a way for a browser to detect whether or not a site was respecting do-not-track headers, browsers could have a setting that allows users to block sites that don't respect them. Enforcement and consequences could come through regulatory requirement or through industry self regulation. Companies need to have some sort of legal or contractual obligation to respect the header (once we figure out what it means to respect it), there must be some way to determine whether or not they are actually respecting it, and there must be consequences for not respecting it. Indeed, with heavy pressure from the Federal Trade Commission to implement do not track, there is significant interest in developing standards around this concept.īesides reaching a consensus on what the do-not-track header means, there is also a need for a framework that allows for some sort of enforcement. Therefore, sending out a do-not-track header is, as Mike Zaneis from the Interactive Advertising Bureau described it to the Wall Street Journal, "like sending a smoke signal in the middle of Manhattan it might draw a lot of attention, but no one knows how to read the message." But browser vendors are forging on ahead with an "if we build it, they will come" attitude, and a hope that some day the smoke signals will take on a useful meaning. As of yet we have no agreement on what it means to track, let alone what it means to not track. There is ongoing discussion about what a do-not-track header actually means and what websites should do when they see it. And today IE9 is here with Tracking Protection lists and Do Not Track headers. Then yesterday Microsoft announced that IE9 would include the ability to set a Do Not Track preference as well. In the mean time Firefox released a beta "Do Not Track" feature that allows users to configure their browser to send a header to every website that transmits a user's preferences not to be tracked. Microsoft had announced and previewed their Tracking Protection feature some time ago, which allows users to setup lists of websites with which all third-party interactions are blocked.
