Security Ring denies intruders when you're away

Fingerprint scanners are so 2004. Yang Hai, an artist who apparently appreciates utility, has conjured up a concept that aims to make biometrics on PCs a thing of the past, as his aptly-dubbed Security Ring makes certain that no one can peruse your files while you're away. The device enables the user to select a lock down distance, and when the ring bearer exceeds that parameter (or simply heads to the lavatory), the connected PC locks out intruders and only opens up when its master returns. Talk about a hit waiting to happen in the corporate space.

Wouldn't that be like a lot less secure then biometrics?

[egåroht @ Jul 20th 2007 9:47AM]

What could possibly be less secure than biometrics? Anyone can get to your finger prints from the the door knob or your iris scan from a close-up photo.

[Mr. Vage @ Jul 20th 2007 10:53AM]

Watch the Mythbusters episode where they defeat a fingerprint scanner with a piece of paper.

[nyleharris @ Jul 20th 2007 11:48AM]

they didnt defeat that myth with a piece of paper. It took them about 4 different attempts and three days, and they actually used a ballistic gel to accurately do it. Most fingerprint scanners also allow the user to set an accuracy rate of the fingerprint up to 99%, and the mythbusters episode didnt show what that level was set to, meaning it could have been set anywhere far underneath that. The one they defeated also appeared to be an optical type,( "read" and then compared) which is far more accessible than the more protected galvanized systems.

[Trent @ Jul 20th 2007 12:22PM]

Any computer can be fooled. The problem with biometrics is that it's actually pretty easy to get a copy of said biometric. Finger prints are trivial to acquire in that you leave them on everything you touch. A facial recognition system can be defeated with a picture, and iris recognition systems can also be defeated by pictures. How you ask? A high resolution facial shot with a flash will also photograph the iris, blow it up some and crop it and the scanner won't know the difference. It's also probably possible to place this photograph on a flexible substrate and embed it in an opaque contact lens (although this is likely well beyond anything but highly advanced espionage).

The problem with biometrics is not that they aren't unique, it's that the computer that is comparing them can be easily fooled. A computer can't tell the difference between a photograph and a real person because they look the same to the computer.

Honestly, all you do by requiring multilevel authentication is add a little tiny bit more difficulty in cracking. The reality boils down to the fact that biometrics offer no security advantage over passwords. The only way biometrics become secure is if you position a real human guard to watch and confirm the authentication so that fooling the computer becomes very very difficult.

Now if you talking about casual theft of a personal laptop, multi level protection may protect the contents, but for real security (ie Corporate or national) it's a joke.

[Wwhat @ Jul 20th 2007 5:03PM]

I'm told that in japan they use a scanner that scans the veins under you finger as biometrics a lot.
I think that's a pretty good idea, it's simple, it's secure, you must be alive, and you don't leave copies of it on everything you touch.

[Chris @ Jul 20th 2007 9:42AM]

If I make a silly 3D rendering of a conceptual device, can I make the front page too?

[Lenny @ Jul 20th 2007 9:50AM]

Realistically none of these are as safe as a good password. As long as its in your head, no one can steal it. Now if your stupid enough to write it down, its no longer secure, but both biometrics and any physical device can be stolen.

[Jerome @ Jul 20th 2007 9:51AM]

press “windows logo” + “L” to lock your computer. Try it NOW!!


Screw the ring!

J-

[Natedog @ Jul 20th 2007 10:15AM]

Alt+F4 does it too...

[Cory @ Jul 20th 2007 10:16AM]

I would try "Windows key + L" but someone seems to have conveniently forgotten to put a Windows key on my Unix machine's keyboard...

Anyway, my major problem with that ring is that it just downright looks like crap.

[Wwhat @ Jul 20th 2007 5:00PM]

You seriously found a keyboard without a windows key? might be that you use linux or something but a keyboard without windows key? now that's radical

[Jerome @ Jul 20th 2007 9:36PM]

Hey Natedog, If people are pressing ALT + F4, I know why you are Lowest Ranked! HAHAHAHAHA!!!

[Samo @ Jul 20th 2007 9:54AM]

Bah... I'm using a better product that's not dissimilar (sp?) to this... It uses bluetooth tech to check if my phone (which stays on me at all times) is within range, and if not, it'll lock the comp, and auto unlocks when I'm back! Granted, you need to buy a BT dongle and a phone, but the latter is an non arguement because almost everyone has a BT enabled mobile.

It's just my 2 cents on this product.. it's been done already, without having (too much) more hardware.

P.s., I didn't name the s/w because you guys might think I'm a sales rep for those guys or something ;)

[Roger Rees @ Jul 20th 2007 10:07AM]

Well I'd like to know what the software is!

[Christian Martin @ Jul 20th 2007 10:18AM]

Actually, I'd be interested to know what it is. Sounds like it's worth tinkering with.

[Leoedin @ Jul 20th 2007 10:29AM]

Please do name it!

[Paul Chan @ Jul 20th 2007 11:04AM]

yeah, i was about to say it i needed to do that i can just use the bluetooth on my phone!!
i've seen usb locks with keyrings which lock the computer when i goes out of range of a few meters, basically doing the same thing, but costly only £10 and doesn't mean you have this massive metal ring which will be big and heavy coz presumably there will be a battery inside it

[LinuxIdiot @ Jul 20th 2007 11:19AM]

I am guessing the software is LockItNow! I just found it by searching google with "bluetooth locks computer until return"

I may have to give it a try for my laptop! :D

[Will @ Jul 20th 2007 12:32PM]

I'm pretty sure Salling Clicker has this functionality built into it and also allows for remote control of iTunes, WMP, Powerpoint, etc.
Has been a while since I've used it though.

[Samo @ Jul 20th 2007 5:39PM]

Actually, Will is right; I use Salling Clicker on all my home PCs... It's a nice software which I use to remote control all said PCs... esp good when you have a PC linked to a living room TV.

On the BT connections, you can have it set up so that the PC is locked whe you are out of range. I do recommend it as a PC remote

Blimey, I do sound like a sales rep now, but you guys are pretty interested, I guess ;)

[Andrew Jones @ Jul 20th 2007 10:06AM]

So - this device would require a system admin to have the one ring to rule them all?

[jimeagle @ Jul 20th 2007 10:07AM]

You can do this anyway with your phone using bluetooth.

[PJK @ Jul 20th 2007 10:07AM]

I see a lot of severed fingers on the menu for anyone who buys this.

[Christian Martin @ Jul 20th 2007 10:18AM]

There's a USB dongle/keychain combo that does this already. I got two of them from Woot.com over a year ago.

[Jimmie @ Jul 20th 2007 10:19AM]

Damn, I forgot my ring at home! Guess I can't work today ;-)

Wonder how often that would happen.

[Gollum @ Jul 20th 2007 10:24AM]

My Precious...

[rob @ Jul 20th 2007 8:24PM]

I was waiting for an LOTR comment.

[randy @ Jul 20th 2007 11:34AM]

oh, like a password?

[Ed @ Jul 20th 2007 12:06PM]

Unfortunatly this device (like the usb dongle thingies) will only lock the SCREEN of the computer. It doesn't lock the computer its self. In fact, if you have dual screens, only the active screen identified as the first screen will lock. These would be much better products if they hooked into the Windows Lock APIs

Rohos, USB lock... two factor authentication.... something you know and something you have. Check it out.

[Mike @ Jul 20th 2007 12:06PM]

I would like to congratulate Engadget users for posting a whopping 17 comments on this article before referencing Lord of the Rings.

[johnzilla @ Jul 20th 2007 12:07PM]

This is so old.

There have been similar rings in use for 10 years or more, since the first JavaOne conference put on by Sun in SF, circa 1997. I still have one of the original rings jostling around in my junk drawer.

The only difference is the "lock down distance" done wirelessly, which, as others have noted, is also not new.

[johnzilla @ Jul 20th 2007 12:08PM]

Already done.

[Josh @ Jul 20th 2007 12:40PM]

So is everything going to be shrunk down to a ring? I remember an alarm clock on here not long back that was also a ring.

[roglhow @ Jul 20th 2007 5:13PM]

anyone know if there is a publickly traded company handling this product?

[Mickey @ Jul 20th 2007 5:43PM]

Just what Jerome said: Win + L. It takes a second, and with a good password, it's secure--not to mention economical. I can't imagine that other operating systems lack a similar feature.

[andrew harrison @ Jul 20th 2007 10:40PM]

oooh secret decoder rings?

Activate! form of.. Ice Menorah!

[TIMMAH! @ Jul 21st 2007 12:19AM]

Waiting for the cock-ring version. Watch as no-one ever touches your computer again...

[Jim Kerr @ Jul 23rd 2007 10:37AM]

Being afraid of using a biometric scanner for a fingerprint is so 2002!

Biometrics have come a long way in the past 2 years. Ceelox.com has biometric based security software that never stores an image of your fingerprint but rather an algorithm that represents the minutia points of your finger. This renders the chance of spoofing to 10 to the 7th power. Even if someone were to hack the algorithm the system would detect the exact number being fed as a spoof. Also the latest scanners will measure your finger's capacitance which is going to read your finger's electrical charge...a replicated finger with a lifted fingerprint will not give you access anymore. A hacked off finger won't work either!

[Wwhat @ Jul 20th 2007 5:11PM]

The scan of the veins in your finger thing is best I think, no copies are left all over and you must be alive so it's pretty secure and yet respects privacy somewhat.
And about the '2002' quip, surely if something is bad in the past it doesn't become suddenly great a few years later (except for fascism maybe..)
And using keypoints is what's always been used. And capacitance? that is never constant so that's BS, lie detectors work partly by measuring difference in capacitance while you speak, so it's so inconsistent it can't be unique and so can easily be spoofed if you try to use it in fingerprint scanner.

[Jim Kerr @ Jul 23rd 2007 10:58AM]

Things can't become great in a few years????? What? One year in technology is like 10 years...Hi def TV's, cell phones, satelite radio...mp3's ...IPOD's...the computer you are using? Have these things not been dramatically improved upon in just a few years? Biometric readers have also dramatically improved right along with these things so I am not buying that fascism is the only thing that can be improved quickly..Capacitance is very consistent when in comes to detecting weather a person is using a real live finger or a man made fake...so in the context of what it is used for it is very reliable. Again the chances of spoofing the latest biometric reader is 10 to the 7th power and is much more convenient and safer then fat fingering in your username and password...

[teall @ Jul 23rd 2007 10:39AM]

The scan of the veins in your fingers may be very good as is Iris as well as facial and a lot of other things. The problem is they cost too much and how are you going to set up a vein scanner on a laptop or even a flash drive.
The technology advances in the last 3 years with finger prints is pretty amazing. And your statement that key points have always been used is slightly inaccurate. Whether we are using an AFIS system or a non AFIS system, yes we are looking at the points on a finger print. But the big difference is with the older scanner type systems, the ones that work like a copy machine. They kept pictures of your finger print and matched them based on the points on the print but were actually comparing the pictures.. The new systems now don’t take pictures of your finger. They use a mathematical mapping of your finger that is encrypted. Even if you could hack the encryption and somehow get the formula, an exact copy will not work. The software is built to look for slight variations, in other words exact matches don’t match. As for your capacitance BS statement, well that is what it is BS. It is not a lie detector test, it is not looking for changes in capacitance, which is what a Polygraph test looks for. It is looking for capacitance meaning whether you have it or not. Can you fool it yes if you want to take the time and try to create an electric charge, sure. Or you could blow up the system you are trying to steal info from. But that is really not the point. The point is this. I could spend weeks coming up with a way to fool your biometric finger print device. And it would take weeks. How long is it going to take me to figure out your password. 5 min with freeware crackers. Maybe less if I really know what I am doing. It is like having an alarm on your house. If I am a burglar I am probably going to hit your neighbor’s house that doesn’t have an alarm, because it is easy.

[Scott Brown @ Jul 25th 2007 3:57PM]

Just don't drop the ring in the lu- when u go to pu- or you'll be screwed.

[hakan @ Aug 14th 2007 1:04AM]

Is there a more detailed article about this topic?
