Privacy Threat in New RFID Travel Cards?

DemolitionX9 writes to tell us ZDNet has an interesting article rehashing the problems with privacy in future RFID-equipped travel documents and ID. The piece focuses on a recent speech given by Jim Williams, director of the Department of Homeland Security's US-VISIT program. From the article: "Many of the privacy worries center on whether RFID tags--typically minuscule chips with an antenna a few inches long that can transmit a unique ID number--can be read from afar. If the range is a few inches, the privacy concerns are reduced. But at ranges of 30 feet, the tags could theoretically be read by hidden sensors alongside the road, in the mall or in the hands of criminals hoping to identify someone on the street by his or her ID number."

Many of the privacy worries center on whether RFID tags--typically miniscule chips with an antenna a few inches long that can transmit a unique ID number--can be read from afar. If the range is a few inches, the privacy concerns are reduced. But at ranges of 30 feet, the tags could theoretically be read by hidden sensors alongside the road, in the mall or in the hands of criminals hoping to identify someone on the street by his or her ID number.

Unless the Feds are going to come up with an air-tight encryption scheme, this is a recipe for disaster. This isn't like the EZPass I have on my car, which is only linked to my account and determines if I have enough to pay the toll. These chips will potentially carry a lot of personal and very useful information, especially if you're a crook looking to use somebody's id to get across the border or to create fake identity documents for sale.

Frankly, this whole idea is mainly a panacea. If it works, the bad guys will simply sneak across the thousands of miles of undefended and unmonitored border we have in the US. Others will start turning innocent people into mules by swiping their identities and using them to get things across. Instead of making the borders of this nation more secure, the government is creating even more insidious ways for someone to come into this country. I think it's time to go back to the drawing board.
