New Service Tracks Missing Laptops for Free

Researchers have developed a free open-source laptop tracking system for laptops called Adeona

Lose your laptop these days and you lose part of your life: You say good-bye to photos, music and personal documents that cannot be replaced, and if it's a work computer, you may be the source of a very public data breach.

But now, researchers at the University of Washington and the University of California, San Diego, have found a way to give you a shot at getting your life back. On Monday, they plan to launch a new laptop tracking service, called Adeona that is free and private.

Named after the Roman goddess credited with guiding children back to their parents, Adeona uses software that has been under development for the past year.

Here's how it works: A user downloads the free client software onto a laptop. That software then starts anonymously sending encrypted notes about the computer's whereabouts to servers on the Internet. If the laptop ever goes missing, the user downloads another program, enters a username and password, and then picks up this information from the servers, specifically a free storage service that has been around for several years, called OpenDHT.

The Mac version of Adeona even uses a freeware program called isightcapture to take a snapshot of whomever is using the computer.

Adeona doesn't exactly give you the address and phone number of the person who's stolen your laptop, but it does provide the IP (Internet Protocol) address that it last used as well as data on what nearby routers it used to connect to the Internet. Armed with that information, law enforcement could track down the criminal, said Tadayoshi Kohno, an assistant professor at the University of Washington. "Once you actually recover information about your laptop...you probably want to take this information to the police."

Aviel Rubin, a professor at Johns Hopkins University who is familiar with the Adeona project says he wants to download the code when Adeona goes live. "Not all the information that you're going to get in every circumstance is going to find the laptop or catch the bad guy," he said. "But this is a pretty big step forward."

"Without this, you could pretty much kiss the laptop good-bye," he added.

When the team first started work on Adeona it wasn't the tracking and retrieval of missing laptops that piqued their curiosity. It was a privacy problem: How could they build a laptop tracking service that was so private that even the people running the service could not discover the location of the laptop? That information would be accessible only to the user, Kohno said.
