Does NAI’s Opt Out Tool Stop Consumer Tracking?

by Ryan Calo, posted on April 27, 2009 - 3:52pm

I heard a rumor that I hope isn’t true. Specifically, I heard that opting out of behavioral profiling may not stop advertising companies from tracking you as you travel across the Web. Rather, according to the rumor, in many cases you merely opt out of seeing the tailored ads your web history might otherwise trigger.

The ability to opt out of behavioral profiling essentially underpins the argument for self-regulation by the industry. The idea is that (1) people like tailored ads and (2) those that worry about the practice, for instance, from a privacy perspective, can opt out of it. Setting aside the apparent frailty of cookie-based opt out (when you delete your cookies, you delete your opt out as well) and the availability of other means to track users (like flash cookies), this seems pretty straightforward and convincing.

But what does “opting out” mean, exactly? A close look at the Network Advertising Initiative website, which offers an opt out tool on behalf of most major online advertisers, turns up no guarantee that opting out will stop a company from logging where a user has traveled.

The Dynamic Balance Between Free Speech and Privacy Interests

by Sarah Hinchliff..., posted on April 17, 2009 - 2:19pm

There have been a host of apocalyptic warnings in the blogosphere about the First Circuit’s recent decision holding that truth is not an absolute defense to a defamation claim. One blogger dubbed it “the most dangerous libel decision in decades,” and nearly everyone predicts it could have serious implications for journalists. But instead of joining the chorus of First Amendment advocates decrying the decision, I propose we take a step back to calmly examine the appropriate level of First Amendment protection for truthful private information.

The True Danger Of The Internet: What Occurs To Us

by Ryan Calo, posted on March 30, 2009 - 1:32pm

The most interesting aspect of cyberspace is not what happens for a time to its visitors. It’s not the absence of regulation nor the presence of perfect regulation; it’s not the staggering variety of content nor the sudden arbitrariness of geography; it’s not the constant threat of surveillance nor the occasional absence of accountability. The most interesting aspect of cyberspace flows from its status as an engine of realization: cyberspace widens the range of what we think of as possible. The Web is home to phenomena that never quite happened before—not because the technology was untenable, but because no one thought to do it. The importance of cyberspace is not what occurs to you when you visit; it’s what occurs to you.

If you’ve visited Google’s physical campus in Mountain View, you likely noticed that the sign in procedure amounts to a click-wrap. Google requires that you accept a non-disclosure agreement, presented on monitors by the front door, before it will print you a visitor pass. It occurred to the Internet giant that it could treat its campus like an Internet service by requiring visitors to click-through a terms of use at the entry portal. This generates a record that you either agreed to play by the rules, or you were trespassing.

This is hardly an isolated example.

“Everything. I record everything.”

This quote belongs to Robin Bienfait, RIM’s Chief Information Office (CIO). RIM makes the BlackBerries, and the title line of this post recites Ms. Bienfait’s answer to the question what information is being recorded on RIM’s internal network (e.g., telephone conversations and email exchange over employees’ devices).

See Otter

by Ryan Calo, posted on March 3, 2009 - 2:38pm

As if we privacy advocates didn't have enough to worry about, this sea otter apparently got a hold of a video camera and was "filming" tourists. Witnesses speculated that some boater dropped the camera and this fun-loving, puppy-of-the-sea found it floating in the Bay. But of course you and I know the terrible truth: DARPA microchips...

As part of Data Privacy Day 2009, the Center for Internet and Society hosted a Privacy Policy Workshop, sponsored by Covington & Burling LLP. I've attached our PowerPoint slide deck. You can follow along to an audio recording of the event by clicking here.

We had a great turn out and a lot of interesting questions. Thanks to Covington & Burling LLP, especially Mali Friedman for her presentation, and to Intel, especially Jolynn Dellinger, for coordinating Data Privacy Day.
