Last week the Federal Trade Commission called on companies to find a way to offer consumers the ability to opt out of online ad tracking. Today, Microsoft took a significant step toward answering that
call.
The company just announced that its next version of Internet Explorer
will offer do-not-track functionality in its browser.
To accomplish this, IE9 will replace the current InPrivate Filtering feature with a no-tracking function that will allow users to input a
"blacklist" of servers. The browser then will refuse to put through calls to those servers by the Web site the user has navigated to.
The browser itself wouldn't compile the blacklist. Rather,
consumers could pick and choose from a variety of potential lists. Presumably these could include compilations developed by industry groups -- which might be comprised of servers that don't comply
with self-regulatory principles -- as well as ones developed by privacy advocates, which potentially could include all ad networks that engage in third-party tracking.
Already some industry
observers are waxing enthusiastic about the upcoming offering. Privacy expert and security researcher Chris Soghoian calls it "a great, pro-privacy and strategically savvy move on Microsoft's part."
But, he warns, ad
networks could try to find workarounds by "further embracing alias subdomains and other sneaky techniques."
Jules Polonetsky, co-chair and director of the think tank Future of Privacy Forum,
also said the new feature seems to answer regulators' recent call for the industry to develop do-not-track functionality. "It should more than satisfy the FTC," Polonetsky says. "It's enormously
powerful -- far more powerful than the industry would like."
However, he adds, people still must enable the feature and then obtain a blacklist -- which few average Web users appear likely
to do.
