HP's Memory Spot Chip

Iddo Genuth writes, "HP Labs recently revealed a prototype of the Memory Spot Chip, a tiny wireless chip capable of storing and transmitting data. When it hits the market in about 2-3 years, the new chip will enable a variety of applications ranging from digital wristbands that store patient medical information to sound bytes on paper or printed pictures that can be accessed using a reader-equipped device. The article has an interview with Howard Taub of HP Labs and some photos of the prototype chip." The chip can only be read at a distance of 1 mm, so it avoids many of the privacy concerns of RFID. It has about 1000 times the storage capacity and 100-1000 times the data transfer rate of RFID.

      I don't believe it's an issue... you'd need the pringles tube around the chip to make any significant distance, as this is the bit that you can't significantly increase its broadcast power (as it's just too small to collect, handle, and transmit a large enough amount of energy, no matter how much energy you send to it). Without that, you amplifying (either using more power or a directional antenna) your signal to it won't make any difference, it can't reply with all that extra power, and so you're going to have a greater difficulty differenciating between the signal and background radiation the further away you get.

      Other than that, the idea of getting someone to put a pringles tube around their chip so you can "secretly" read it is a bit absurd, so I really don't think we have anything to worry about.

RFID and Bluetooth were both touted and very short-range technologies - until enterprising minds figured out how to get Bluetooth over a mile an RFID to meters.

      I'm not saying that the limit can't be broken, by 10, maybe even 100 times the distance... but nothing to be worried about. Sure technologies like bluetooth and wifi can stretch over their spec'ed distance, this can be achieved with various methods such as increasing the power to the antenna and/or using directional antennas. But if you're not going to notice somebody attaching a directional antenna to the memory chip, then you quite frankly have bigger worries. Also, the micro circuitry in something as small as the chip isn't going to be able to handle a huge amount of current without it getting hot 'n blowin, so there's a hard limit to how much you can increase the power to it. So no, I don't think it's anything worth worrying about.

    The chip can only be read at a distance of 1 mm, so it avoids many of the privacy concerns of RFID.


    Unless they have discovered some new fundamental property of electromagetism, what this has to be read as is this: The system was designed so that the specific reader they have in mind is not capable of reading at greater than 1mm. This says nothing about security because it does not preclude a reader of a different design from reading the devices at a greater distance.

    There is no doubt that this technology is more difficult to snoop than RFID. However, I suspect that talking about a technology like this being "secure" entails the logical fallacy of "begging the question" -- the question in this case being who and what we trust it to secure us against.

    It is not the technology, but the trust we put in it that creates security vulnerabilities. That trust creates incentives to exploit our sense of security.

    Suppose I am a diplomat who trusts this device to keep my country's secret negotiation records secret. This create the incentive for foreign intelligence agencies to build hidden readers into the conference table so when I put my portfolio down the thing gets read. Or maybe they build supersenstive receivers and efficient antennas to read the device from several meters away.

    Suppose I am a billionaire who trusts a chip embedded in my palm to keep my secret bank access codes safe. I create the incentive for somebody to chop my hand off.

    So, by advertising a system as "secure", especially making broad claims such as it being impossible to read at greater than 1mm, we create security problems.

    Another thing to consider: even if the things cannot be read at more than 1mm, they can surely be detected at a greater distance. For example those medical record dog tags might reveal the position of a commando at several meters.

    IANARG (I Am Not A Radio Geek) but it seems to me you have to do is look at is the physics of how the devices work in order to assess their security -- not the system in which they are designed to work. At 2.54 GHz, the wavelength these devices operate on is about four and a half inches. If you look at the reader, it clearly is designed with an inefficient antenna, which must be the major factor limiting its operational range.

    A 2m dish, which could easily be hidden behind a RF transparent screen, would have 35 dBi gain. This clearly could read the devices at a much greater range.

    A more precise statement of security than "cannot be read at more than 1m" would take into acount the size of the antenna and the distance at which that antenna might be located.

    Suppose, for sake of argument, that the practical limit using a 2m parabolic dish was that the devices could be read at 5 m and detected at 15m. We could make make a table:

    At over 15 meters: I am secure from detection by a hidden 2m dish.
    At over 5 meters: I am secure from disclosure to a hidden 2m dish.
    At over 4 meters: I am secure from detection by a hidden 1m dish.
    At over 1 meter: I am secure from disclosure to a hidden 1m dish and detection by a simple dipole antenna.
    At over half a meter: I am secure from disclousre to a simple dipole antenna.

    (values are hypothetical and sloppily estimated, but you get the idea).

    The problem is, it takes more of an attention span to think about this than to assume you're safe at anything over 1mm.
