Unsettling Thoughts about Reality, Virtual Reality, and "the Digital Force"

8/4/2004

By Terry Calhoun

Remember the original Star Wars scene where Obi-Wan Kenobi, Luke Skywalker, CP3O and R2D2 are entering the town of Mos Eisley, on the planet Tatooine. They're stopped by a suspicious stormtrooper but Obiwan uses his Jedi powers to cloud the man's mind: Obi-Wan: "These are not the droids you're looking for." Trooper: "These are not the droids we're looking for."

Now, imagine that, instead of "the force" permeating the universe of Star Wars, instead we use, to the same end, the digital and automated reality our culture is currently constructing for itself. At the Black Hat Security Briefings conference in Las Vegas recently, Lukas Grunwald, a German information security consultant recently reported on one way he thinks he can use this "digital force" to cloud retailers' minds.

Lukas Grunwald says that he has created software that will let him enter a store and, using a PDA, copy product identification information from the RFID tags on a number of products. Then, as an example, he can also use his PDA to take the product information from the tag on a $3 carton of milk and feed it into the RFID tag on a $15 bottle of luxury shampoo. In the currently hypothetical fully-automated supermarket that is probably in our near future, he trundles his cart through a checkout lane where the contents are totaled up and walks away with the luxury shampoo for only $3. Consider that Lukas is in the role of Obi-Wan Kenobi, the automated checkout counter is in the role of the stormtrooper, and Lukas' PDA is the tool with which he manipulates "the digital force." (A more chaotic version of manipulating the digital force with regard to RFID which I read about on an anarchist website is to release, in a large store, cockroaches with fake product RFID tags glued to their carapaces.)

Read the script below.

Grunwald has released his software, for free, to prove his point.

What a magical time it was in 1977 when Star Wars transformed science fiction entertainment forever. Little did we know that we were already engaged in building our own version of "the force." Every year and now it seems every month I learn of a new technology twist that adds to the invisible-to-the-eye sea of digital information that flows around us and creates the environment we interact with.

"Really?" you say. "The force?" and I say, "Yes, the digital force." It's nearly everywhere and it will be soon. It's certainly in your office, and at the ATM machine, and in jet fighters, and you can even tap into it anywhere inside the city limits of Grand Haven Michigan now.

And it's available anywhere you can get a cell phone signal, like on many interstate highways. I was recently on a long trip in Clifford, my big red truck, through Alabama, Georgia, Kentucky, and Tennessee, with my son driving at 70+ miles per hour. For most of the trip I was able to work as though I were in my office - using my Dell Inspiron 8500 which was getting power from Clifford and dialed up to the Internet through my Treo 600 converged device, catching Sprint signals nearly constantly. If that's not tapping into a digital force then I don't know what is.

From the script of "A New Hope," "Star Wars" Episode IV - a scene each of us knows almost by heart:
