RFID Cards to Include Tin Foil Hats? 248

An anonymous reader writes "The tinfoil hat finally gains government approval. From the story: 'Wrap an RFID chip [of the US passport] inside a Faraday cage, and the electromagnetic waves from the chip reader can't get in and activate the chip. The State Department says it may use the principle to give travelers an added sense of security. No, there won't be rolls of aluminum foil included with every passport. Instead, the passport cover may include a network of wires woven into the fabric. Fold the passport shut, and there's your Faraday cage. Even Schneier agrees that a properly shielded passport cover should solve the problem. He wonders why this wasn't included in the original plans for the new passports. 'It took a bunch of criticism before they even mentioned it,' Schneier said. And he hopes the anti-snooping technology is thoroughly tested before the new passports are introduced next spring.'" We've also seen this suggested in the past.

    Personally I have found that if you use a double layer of tinfoil when fashioning your headwear that it more than doubles the effectiveness! This is due to a resonance effect between the two layers of tinfoil which resonates precisely at the frequency of the government's invisible brain lasers.

    In addition, if you fashion two antennas on the top of your hat instead of the usual one, it increases the effectiveness by an additional 37 percent.

      This isn't a trivial concern. People with dual citizenship are at risk in some countries. If you're a citizen of country X leaving country X, you may not want the security people to know that you're carrying a US passport. You may have no choice but to carry it, but making it metallic practically guarantees that you'll have to show it to security. Of course the same thing applies if other countries use RFID tags with metallic shielding.

      • by TLLOTS ( 827806 )
        Err... couldn't you just put your passports in whatever bag you carry on the plane? That way when you go through the metal detectors, you just take your bag off, and you don't have to worry about passports showing up via metal detection. Keep them close together in the bag and when x-rayed they may not even be able to tell there's two in there. Though I could be very wrong about this, so take it with a grain of salt ;)

        In the countries considering RFID (US and many more, unfortunately), the governments' thinking with respect to RFID seems to be flawed in many ways:
        • They (incorrectly to their own knowledge) deny implications of RFID (in passports or otherwise) for the bearer's personal safety
        • They want to force RFID chips inside passports
        • Then they promise to shield it so the passport needs to be opened anyway - but could still be identified as e.g. a US one even when closed, and potentially still be read out with special (i.e. simply more powerful and/or sensitive) equipment, despite the apparent perception of security
        • Unlike with optical reading, where the document can simply be put out of sight, the bearer has no way of knowing whether and when an RFID shield actually works
        • Why pretend that only governments (or "the good guys" in general) would be able to procure RFID readers? This technology is not rocket science, and it could be every thug's dream come true (especially as the European Central Bank even seems to consider putting it into their money) - so "finally" for the nastier elements of society, remote assessment of who might be a "promising" victim e.g. for abduction, robbery or worse becomes possible
        So there is always certain inconvenience -if not danger- to the bearer, but not a single valid reason for embedding RFID into a passport: If it needs to be opened anyway, and faster machine-readability than with the current (already standardized) printed text is required, a simple printed barcode would do, at much greater reliability. Make no mistake, if RFID is enforced even though it does not have any benefit in the proposed application, there have to be ulterior motives for its use - then, however, it is no conspiracy theory to suggest that future mischief is implied in this scenario.
        • A further point: RFID's supposed advantage of high capacity for data storage is easily rivalled by a full-page 2D barcode.

          A standard PDF417 barcode contains about 1kB of data in 35 x 9mm. That's 315mm^2. My passport has a useful printable area of roughly 9600mm^2. That means that a single passport-page-sized 2D barcode could hold roughly 30kB.

          Of course, anyone can print barcodes. But then, relying on the inaccessibility of RFID programming and reading equipment is security through obscurity at its worst.
          • It may take some time for RFID readers and writers to be commercially available, but it will happen, just as anyone today can buy magnetic card equipment.

            First, these aren't RFIDs, they're contactless smart cards (the difference is one of degree, not type, but important nonethelesss). And contactless smart card reader/writers are already commercially available, and cost between $70 and $200.

            However, the chips are not just passive data stores, like a magnetic stripe or a barcode, they're microprocessor

            • If the chip refuses to divulge the data until you've successfully authenticated yourself via a cryptographic challenge/response protocol, just having a reader won't do any good.

              Although the govenrnment is not talking about cryptographic protection on reads (though they really, really should), they certainly will configure the chips to require a strong authentication for writes. It's very unlikely that you'll ever be able to modify the data on a passport like you could if it were encoded on a magnetic med

    Naturally, I agree with the majority of people here that RFID passports are insecure, a threat to our privacy, and just generally a bad idea. However, I see a bigger problem here-- and a trend that's been growing over the past few years, at airports in America as well as in other countries. Airport security has already essentially dropped the facade of "random" checks; my male relatives (of Israeli descent, but most holding American passports) have all been interrogated/strip-searched/had the bomb squad called on them in the past few years at various airports throughout the world, for no justifiable reason. I find it pretty ridiculous that governments are spending so much money paying people to do things such as spend 2 hours detaining/interrogating a random girl (me) and doing things such as turning my violin upside down and shaking it violently, repeatedly turning my laptop on and off, etc., asking me idiotic questions ("why do you have this computer? what are you using it for?"). At any rate (sorry, got a bit off-track there), the real problem I see is this: airport security/governments in general already have such ridiculous criteria for profiling thought criminals (oh excuse me, "suspected terrorists".) It's bad enough to be detained/searched in this manner on a regular basis simply because of your ethnicity or appearance, but with RFID passports, passports containing a smartcard, etc., they can just take it one step further and start flagging "suspicious" people even more easily. Maybe I'm on the wrong track, but I really fell that the biggest threat here is not random criminals trying to steal your data or abduct you (as others have suggested); I think it's government entities with which we should be more concerned.
  • Get a new/renewd passport NOW, i.e., before they start issuing the RFID ones. Passports are now good for 10 years. I doubt that they'll forcibly retire all existing ones at once, since it would cost too much, they'l probably replace them all by attrition, and now you'll have 10 years until renewal.

    By then, it might have been successfully fought, or there could be good tested workarounds to the problems.
