Privacy in ubiquitous and home computing

Monday, July 30th, 2007

A talk by Jean Camp at BT Adastral Park on the 1st of December.

The talk discusses privacy in ubicomp as a design, social, technical, and policy issue; outlines the research program at IU that is designed to meet the technical and social challenges of using sensor networks as a monitoring technology.

Privacy in Ubicomp: Devices that Tell on You

Wednesday, June 6th, 2007

At USENIX Security, a paper will show how three consumer devices leak personal information.

We analyze three new consumer electronic gadgets in order to gauge the privacy and security trends in mass-market UbiComp devices. Our study of the Slingbox Pro uncovers a new information leakage vector for encrypted streaming multimedia. By exploiting properties of variable bitrate encoding schemes, we show that a passive adversary can determine with high probability the movie that a user is watching via her Slingbox, even when the Slingbox uses encryption. We experimentally evaluated our method against a database of over 100 hours of network traces for 26 distinct movies.
Despite an opportunity to provide significantly more location privacy than existing devices, like RFIDs, we find that an attacker can trivially exploit the Nike+iPod Sport Kit’s design to track users; we demonstrate this with a GoogleMaps-based distributed surveillance system. We also uncover security issues with the way Microsoft Zunes manage their social relationships.
We show how these products’ designers could have significantly raised the bar against some of our attacks. We also use some of our attacks to motivate fundamental security and privacy challenges for future UbiComp devices.

Baja Beach Club in Barcelona. Bikini-clad waitresses serve drinks to guest as a DJ mixes music from a motorboat perched above the dance floor. The club is the biggestg “beach club” in Barcelona and has also a member-only VIP area. To be a member, you need to get implanted an RFID tag in your arm. The tag is encoded with your credit card number for quick and easy payment. Conrad Chase (the club’s owner) points out that many people already have pierciengs and tattoos. “Having a radio-transmitting chip under your skin makes you very unique”, he says. Ya, right!

American Express is a step ahead of Conrad. The company has patented a technique to track people in the public places based on the RFID tags in their clothing and products they carry.

Animal Tags for People?

Friday, January 12th, 2007

Two cousin companies bet the fast-expanding market for animal RFID chips will extend to humans before long
… Digital tags are expected to be affixed to the U.S.’s 40 million farm animals to enable regulators to track and respond quickly to disease, bioterrorism, and other calamities. Opponents have many fears about this plan, among them that it could be the forerunner of a similar system for humans. …

Well, all you conspiracy buffs, let me introduce you to Kevin McGrath and Scott Silverman. … more

Nike+iPod and Privacy

Monday, December 4th, 2006

Nike+iPod allows runners to track their distance, speed, and amount of calories burned after a jog. But it can also be used as a tracking device, without the knowledge of the person being tracked (UWNews).
