NTT's Cool - Human Area Networking Technology 248

kvsnut writes "I4U is reporting about NTT's research project called RedTacton - It 'safely turns the surface of the human body into a data transmission path at speeds up to 10 Mbps between any two points on the body.' There is a pretty interesting site (uses flash) setup to showcase the technology. If you want to jump to a non-flash overview, try here. It be cool if I could sync my Treo (I'm saving for) by just touching a cradle (or heck the PC)."

    What's the point beyond the coolness factor? Palm devices can already sync via 802.11b or Bluetooth. Wireless technologies can already go faster than 10 mbps, and are cheap and well-tested. If we can transmit data through the air, why do we need to transmit it through our bodies?

      It may be more secure than bluetooth - you need a physical contact. So for something like a digital keychain it would be quite convenient. It could be more practical than fingerprints (less errors) and let you authenticate just by touching the sensor.

      On the other side, I will need another firewall for this!!!

      It would be awfully handy for implanted computers, like pacemakers. Wireless should be used only in situations where it is necessary. If contact is convenient it is a better idea. Air gaps are good. For instance when we finally get around to implanting systems to improve our senses we are going to want ways to pipe data in and out of them. Would you like your senses to be on tap (or for rent) wirelessly? I didn't think so. On the other hand, you could have optical and audio interfaces implanted, and have a

      Well, here's one thing: Security.

      One thing we lost when we went from wired to unwired is security.

      That is: A physical cable is a physical incarnation of authorization. Without that cable, we now have to put password mechanisms and other authorization stuff into previously simple connection.

      This body network is another, easier, mechanism for authorization. If the two components are connected by your body, they are authorized to talk with one another.

      Now we just have to worry about people running past to touch you, in order to steal the photographs off your camera, or whatever.

    The real drive behind this is the usage for mobile phones. Here in Japan, mobile phones have become the dominant data handling device. Phones here have the full rolodex, appointment calendar, mp3 player, as well as Final Fantasy/Tetris/CowboyNeal game-of-choice. There are adapters coming online now that will let people browse MSWord and Excel files via their mobile.

    But the drive here is a great social need: when groups go out to dinner, friends, co-workers, business partners, etc. there is always this 10-minute ritual where everyone has to call everyone else in the group, in order to capture their phone number and contact information. If NTT can issue phones where everyone trades this information by touching hands, then they have an edge over the others.

    Japanese protect their privacy vehemently, but are also information hoarders much greater than their US or EU equivalents. Phone rolodexes are huge-- people have every contact they met in the last 4 years (which is in the thousands if you work in Tokyo).

    I think this would be a good thing, since this technique would make it feasible to interface your 'preferences' (stored on a wearable computer) to various electronic or smart gadgets (a smart car/house/etc) so that as soon as you touch it, then the smart gadget is customized to you.

    I suppose a simple application, would be if all cars supported this, then as soon as you touched the door latch then: 1) The car door would open, since the car verified who you were. 2) The seat would adjust to your body height 3) The radio would automatically tune itself to your preferences 4) Your playlists would be imported into the radio.

    Your preferences can be stored in something relatively small. For example your watch can have this technology and it transmit your preferences to whatever smart gadget you touched.

    What would really be neat, is if there were some method of biofeedback so that you could configure your preferences by 'thinking about it'. At that point, we would have something similar to the "Ancient's 'Automated' Technology" as shown on StarGate: Atlantis tv show.

    This would probably be great for one's own devices (cell, palm) but using it for auths exposes the toucher to a variety of diseases, especially from public interfaces. People would probably be loathe to use this to pay for something, if they have to touch a contact point that's been touched by everyone before them.

    Also, there's the possibility that someone could pick up your auth sig from a handrail or doorknob or something... unless you have to enable the auth for something like the next transaction, or the next x seconds, or key in some kind of id that indicates which touch is authorized. That adds a level of complexity that defeats the whole point of the touch interface.

    The biggest market I see for this (other than the obvious marketing/spy novel stuff) is user authentication. People like myself fear bioauthentication because, well if someone steals your identity, you are pretty much boned.

    With this system, you can have a separate heavily encrypted key for each device you touch, and it can be changed if the need arises.

    Seems to me that the obvious entry point is a new wireless optical mouse with this built in. Then you could buy (or it ships with) a memory unit that the user wears. Poof, instant computer usage...secure password storage, configuration data, small files of any kind.

    My two questions are:

    1) can I do a multidrop connection. There is precious little detail about whether my cell phone, pda, mp3 player, watch, HUD (hey I can dream) all play together seamlessly. If so this will kick so much ass.

    2) IIRC the field surrounding the human body is fairly unique to each person...can it be used as part of a biometric system through such a device. This seems kind of unlikely, but would be an interesting low security id system.

    One fairly serious human limitation is the speed of nerve signals. There's about a 100 ms lag between the brain and the hand, longer for the feet.

    Not that that's not adequate for everyday life, but if the nerves could somehow be rewired to use this channel instead, reaction times could be seriously lowered with very interesting consequences in several different fields, such as sport, combat, driving or any other physical activity where speed matters.

    I realize this will not happen tomorrow, but OTOH I can't think of any fundamental reason that it's impossible.
  • This is a great way to pass data very secretly. All you'd need to do is touch someone and you transfer 10Mb/s.

    10Kb/s is plenty for secret messages.. and you have 2^10 times more than that to play with.

    Perfect for secret corporate data transfers (trading secret info), spy data, insider stock tips, trading public keys (or even one-time pads), or many other interesting "walk near me" data transfers.

    Hmm, next time you're near an oscilloscope, try touching your finger to the input. Inspect the signal. Should be about 2 volts of 60 cycle hum, with maybe 10% ragged noise superimposed. Raise your other hand toward the ceiling lights-- the voltage should go up to maybe five volts of raggedy hash. Now touch something grounded-- the voltage should go down to maybe a tenth of a volt, now mostly high-frequency hash. It's unlikely your body is going to make a good data path. Ungrounded, it's a walking antenna for all kind of noise. Grounded, it's a pretty good short to ground. These folks are trying to make filet-mignon out of road-kill-- not very likely to succeed.
