Now you don’t…

Adam Harvey is a graduate student in NYU’s fabled ITP Program who is putting his considerable talents to work in the service of privacy.  His thesis work, CV Dazzle, is aiming at finding ways to confound computer facial recognition systems. As The Register reports:

Concerned about the proliferation of face recognition systems in public places, a grad student in New York is developing privacy-enhancing hacks designed to thwart the futuristic surveillance technology.

Using off-the-shelf makeup and accessories such as glasses, veils, and artificial hair, Adam Harvey’s master’s thesis combines hipster fashion aesthetics with hardcore reverse engineering of face detection software. The goal: to give individuals a low-cost and visually stimulating means to prevent their likenesses from being detected and cataloged by face-recognition monitors.

“The number of sensors that are going into the public spaces has been increasing,” said Harvey, a student in New York University’s interactive telecommunications program. “There’s a lot of work to be done to catch up to where cameras are going because there have been so many advances in the last few years.”

Although still in its adolescence, face recognition technology is quickly being adopted by governments and corporations to identify individuals whose images are captured by surveillance cameras. At the 2001 Super Bowl, for instance, officials digitized the faces of everyone entering Raymond James Stadium in Tampa, Florida and compared the results against photographic lists of known malefactors.

But Harvey has discovered that face detection can often be thrown off by using makeup to alter the contrasts the technology looks for. For example, dark patterns applied around eyes and cheek bones, as in the image below, are one such possibility.

Harvey asks, “How can hats, sunglasses, makeup, earrings, necklaces or other accessories be modified to become functional and decorative?”; and he explains “The aim of my thesis is not to aid criminals, but since artists sometimes look like criminals and vice versa, it is important to protect individual privacy for everyone.”

As we rework our pick-up lines, we might take inspiration from the memory that it was on this date in 1810 that Beethoven wrote Bagatelle No. 25 in A minor (WoO 59 and Bia 515) for solo piano– better known as “Für Elise” (click to hear).

Some scholars have suggested that “Elise” was Beethoven’s mistress; but others have suggested that the discoverer of the piece, Ludwig Nohl, may have transcribed the title incorrectly and the original work may have been named “Für Therese”–  Therese being Therese Malfatti von Rohrenbach zu Dezza, a friend and student of Beethoven’s to whom he proposed in 1810… not actually so encouraging as an example, since though she turned him down to marry the Austrian nobleman and state official Wilhelm von Droßdik… still, a beautiful piece…
