Exchange Email Addresses With A Handshake

Eye of the Frog writes "Nippon Telegraph and Telephone Corp. and its subsidiary NTT DoCoMo Inc. have developed a device that attaches to your PDA which uses the body's conductivity to transmit data at an amazing 10 megabits per second."

  1. Interesting, but... by rice_burners_suck · · Score: 5, Insightful
    This looks like an interesting technology, but what about the security implications? Suppose in ten years, everybody carries around a tiny device--the futuristic counterpart to today's cellphones--which acts as a phone, voice recorder/MP3 player, PDA, digital still/video camera, electronic wallet, and even contains the digital keys to your house, car, and whatever. All you have to do is touch the doorknob to your house and it'll read the keys from your device and unlock automatically.

    Now ask yourself this: What's to stop crackers from using a root-kit that operates through handshakes to steal information from your electronic device and then use that information to break into your stuff? Is this another one of those technologies that will become totally critical in our everyday lives, and that will also become a huge security problem?

  2. Some things to resolve, but amazing potential by starseeker · · Score: 5, Insightful

    Problems: Stores might rig their doornobs to download your personal information as you go in the store. Privacy issue. Or someone could touch you, and have all your information stored. Think potential stalkers/criminals/etc. Scary. Of course you could always turn it off, I suppose, but if you forget it's a problem. I assume I'm not the only absent minded human around.

    However, there are some interesting possibilities:

    A credit card reader could read your body's electrical signal, as it is also scanning the card. Added consumer security. Even cooler would be if each person had a unique electrical signal their body generates, but I don't know anything about that. Either way, interesting.

    You could make long distance calls from anywhere, and have the phone read your calling card number automatically when you pick up the phone.

    Possibility of electronic "keys" for car/house stored in PDA. Not so good if PDA is lost or crashes, but if you can call the company and say "My PDA is gone - please scramble my house key codes until we can resolve the issue" it might work. Locking the house would be great - simply disable the electronic circuit from the inside and there is no lock to pick. As for someone who tries to crack it while you're out, simply have the system stop taking input for five seconds if it gets a bad signal. With billions of possibilities at five seconds a try, it wouldn't work real well trying to crack it. If you're paranoid, have it take thirty seconds. No more fumbling with keys or those little remote control keychains, either - just touch and open.

    Many issues to resolve, but some very cool possibilities as well.

  3. Now Just Wait a Second by serutan · · Score: 5, Insightful

    Does anybody else think this sounds just a teensy bit flaky? The article says the connection works through clothing ... "Apparel and handbags have their own conductivity, allowing an electrical connection to a PDA that can remain in one's pocket..." Huh?? 10 mbps using the cloth of my pocket as a conductor??

    I have a suspicion that news.au.com is getting one slipped to them. The closest Google result I could get with "NTT NoCoMo skin" is this article about a cell phone that conducts sound through bone and cartilage, enabling you to listen to the call by sticking your finger in your ear.

    Uhhh, okie dokie.
