Eye tracking technology received new attention recently due to its inclusion in the Samsung Galaxy IV phone, where it can (with mixed results, according to reviewers) let users scroll the screen with their eyes or dim the screen when they look away. Clearly this is a technology that has the potential for a lot of clever applications. But what are the privacy implications?

Eye tracking for research was used for over a century before computers (see the quick history outlined in this article). The earliest research, in the 19^th century, actually involved direct mechanical contact with the cornea. Already by 1898, researchers were discovering some really cool phenomena of the human brain. Motion pictures were applied to the problem as early as 1905, and the first head-mounted eye-tracker was developed in 1948, which freed study subjects from having to keep their heads still. In the mid-1970s the first remote trackers were developed that were truly unobtrusive to the subject. By then, research and writing based on eye tracking was booming, not only on the part of psychologists but also the military.

The FBI doesn't think it needs a warrant to read emails and other electronic communications – despite the fact that a federal court has ruled that doing so violates the Fourth Amendment. Ben Wizner appeared today on Democracy Now! to discuss this and other ACLU revelations regarding government surveillances practices.

The ACLU this week released documents that paint a disturbing picture of the authority the government claims to access a wide range of our communications – from emails to Facebook messages and much more. These latest developments reinforce what has long been clear: it is well past time to modernize ECPA, the egregiously outdated law that governs our electronic privacy but hasn't been updated since 1986, before the World Wide Web was even invented. As Wizner said:

When the CIA director cannot hide his activities online, what hope is there for the rest of us? In the unfolding sex scandal that has led to the resignation of David Petraeus, the FBI’s electronic surveillance and tracking of Petraeus and his mistress Paula Broadwell is more than a side show—it's a key component of the story. More importantly, there are enough interesting tidbits (some of which change by the hour, as new details are leaked), to make this story an excellent lesson on the government’s surveillance powers—as well as a reminder of the need to reform those powers.

With tax day behind us, taxpayers may soon have something else to celebrate from the IRS. In testimony before the Senate Finance Committee today, IRS Acting Commissioner Steven Miller was questioned aggressively about documents released by the ACLU last week that indicate that the IRS does not think it needs a warrant to read all emails and other electronic communications during criminal investigations. Under pressure from senators, Miller agreed to update IRS policy documents within 30 days to state that a warrant is required for access to all emails, regardless of their age.
