- ryanknapper, on 10/12/2007, -5/+25I don't think hadem is married.
- retinaburn, on 10/12/2007, -0/+7I wish I could get RFID's cheap. Cory Docotorow, and various other people have proposed the tagging of objects in your house, and then you just store them in buckets/drawers/etc wherever there is space for them. The storage devices have rfid readers so when you want to find something you go to the interface/computer and search for say 'my f*cking keys', and it will show which container holds your keys.
It's like how a harddrive works. You don't care where physically the data is stored, you just care that your reference to the data works, then you manage the references in some sort of reasonable manner.
The prices are cheap enough now for the readers & tags to get a small quantity to play with, but all in due time. - rrittenhouse, on 10/12/2007, -3/+8Well if you pick someone thats attractive you wont have this problem :)
- Dag_Yo, on 10/12/2007, -0/+5For the security question: "security?? I think not, any smart person with a RFID reader and a powerbook and a few minutes can crack it SO HA!!"
This entails getting ahold of the tag that has access to the door and (presumably) reading the tag, then somehow generating a similar tag or signal response in order to fool the reader into thinking you have the tag. Wow, that was a mouthful.
My question is this: If the smart macbook-equipped thief with more than half a brain decides that he's going to try to "hack" your RFID door locks, how would he ultimately do this?
1) Stand outside and run through (brute-force) all of the combinations of potential tags?
No, because the reader has a 5 second delay from the time that an invalid tag is used and the next time he can try one. Read the site that sells the kit.
2) Steal your tag, read its signature and somehow generate another tag?
No, because the tag is in your pocket. How is this different from stealing your keys, running to Home Depot and having copies made? It's harder to do, that's the difference... would require much more dedication, technical savvy, time and money.
Note: Yes, you can read the tags from far away. Quite far away. Granted. This hypothetical example though would require espionage-caliber dedication on the part of the crook trying to steal your big screen TV. Be realistic...
3) Turn off the power and walk right in?
No, because fail-secure locks (the most common) will not open once the power goes out. A fail-safe lock will open if the solenoid loses power; however a fail-secure model will remain locked. The deadbolt is battery operated and is therefore unaffected.
4) Kick the door down?
No, because it's just as easy to kick the door down regardless of whether or not you've got a RFID-enabled latch or not. It might actually be more difficult to kick the door down on account of the solid metal strikeplate being anchored more firmly into the doorframe than a standard piece of sheet metal.
So, security naysayers, I beseech you to prove me wrong. Show me some way--any way--that this is any less secure than a standard lock-and-key. - boomerxl, on 10/12/2007, -0/+5security??
I think not
any smart person could open that through brute force........wait, that'd work on any door.
But it would eliminate the problem of misplaced keys. Just remove the old ID and add a new one. Solved. Plus you get complete control over who can use their keys and when. No more sneaking in after curfew. - inactive, on 10/12/2007, -4/+8Yeah, and while they are standing by my front door cracking the lock, my neighbor will blow off their skulls.
- quesera, on 10/12/2007, -0/+4If you're going to limit yourself to two words, I recommend choosing them carefully.
The word you're looking for is "overflow".
Some people also recommend knowing what you're talking about before doing so, but that's not popular around here, so I won't make a big point out of it. - icefitz, on 10/12/2007, -0/+3Umm it is called a lock pick. Man i think digg had a vid showing how easy locks are to pick. So i think that this system had about the same level of security as a standard lock. Even if some one took the time to brute force the tag.
- inactive, on 10/12/2007, -0/+3Everyone that says easily cracked, do you really think the average robber knows how to work with rfid?? If they wanted to get in your house its pretty easy to just break a window. That seems a lot easier then cracking rfid.
- dbr_onix, on 10/12/2007, -0/+2It's a cool idea, but it seems a bit impracticl, but, for something like phsyical secruirty to a smallish server room, it could be quite nice, since you'd have a bunch of computers, in a small room that already has a bunch of wires everywhere (So no need to keep all the wires hidden, like would probobaly be required if it was used for normal house entry), and to be honest, I'd rather trust a server room to this than a house.. You can back up your servers data, but you can't really back up posessions.
That aside, it's probobaly more secure, since not everyone can/would want to have their doors locked all the time (Depends where you live though, in flats etc, most outside doors are locked all the time), where as requiring the RFID tag to be with you is more convientent.. Also, being able to unlock the door from SSH would be usefull, forget your "key", go next-door, ask to use your neighbours computer, remotely login and open your door..
If nothing else, the noveltey value is worth it alone :)
- Ben - inactive, on 10/12/2007, -0/+2Cool thought. Too much hacking involved for my taste, although that would increase the security by itself.
- kc7gr, on 10/12/2007, -1/+3I'm surprised no one else caught a fairly obvious error in the assembly instructions. The article's author identified the 'anode' end of a diode as being the one with a color band.
This is NOT correct. The banded end of a diode is the cathode. Worse, following the article's assembly instructions to the letter will have said diode hooked up backwards, short-circuiting the relay coil and (probably) causing some magic smoke to be let loose.
Others have already pointed out the (painfully obvious) security flaws in this project. Don't even get me started on 'Kwikset' as a choice of locking hardware... - mcglothi, on 10/12/2007, -0/+2I'm a security systems admin and I work with RFID badges / readers in our access control system. There are a few things I would want that this project doesn't include (like some sort of encryption between the card and reader). While this is a pretty cool project and I might try it just to do it, you can purchase readers from Securakey or other vendors for >$200 and have a polished product to hang on the wall, but...
I think I'll stick with this: http://www.smarthome.com/5161.html
There are cheaper ones but after researching the operation of them (user adds/removes) I've decided to spend a little more and get that model. It also has emergency contacts for a 9v battery on the outside so you can power it if the internal battery runs out on you. - Kazrog, on 10/12/2007, -0/+2Just what I need, somebody hacking into my house!
- cheeze69, on 10/12/2007, -0/+2It appears that the relay controlling the strike is in the externally exposed box containing the reader. That is maybe OK for something inside your house where you just want to keep the wife/kids out of, but for a front door or something you really want "locked" that's a huge hole. With the strike-control relay available to the person wanting to break-in, it is trivial to activate the strike, whether it's using power already in the RF reader box or even just carrying a small power source. A quick connection to the strike-solenoid wires and click, in you go.
So, for a front-door type application, make damned sure you only expose the USB portion of the circuit into the wild and keep the strike-relay/etc. unavailable to at least make the crook's job harder (ie. they'd have to hack the RFID code or something like that rather than just connect some batteries). - Ryosen, on 10/12/2007, -2/+4What do you do when the power goes out?
- Mesach, on 10/12/2007, -0/+2Also i would think that a simple Computer UPS would keep this system available for days with the power draw that it uses, then you would still be able to access the location.
- Tekmazter, on 10/12/2007, -0/+2"""Changes to the database structure could allow certain tags to be allowed through only certain doors at certain times. If you wanted to, you could create a crazy maze of doors with readers and time restrictions for certain tags so that a maze-runner has to not only make their way through the maze, but also try doors at the right time. They may or may not be allowed back through the same door they just came from. It could be great RFID fun!"""
This sounds like the movie 'CUBE'. All he's missing is some moving cubes. - sporkwitch, on 10/12/2007, -0/+2Cool idea. Could probably set it up so that if you pass a certain threshold (most likely the main doors to your house) an alarm goes off. Not to mention no more wondering where that damnable memory card with your thousands of hours of savegames went.
- Meshyf, on 10/12/2007, -0/+2very cool, Wish I had some cash to give it a shot.
- MatthewTheRaven, on 10/12/2007, -1/+2"security??
I think not
any smart person with a RFID reader and a powerbook and a few minutes can crack it"
You know, after reading a few stories on lock picking, I was really interested in trying to learn how to do it. I ordered a cheap set of lock picks ( - dmilam, on 10/12/2007, -0/+1Now if everyone in your family had an RFID tag implanted in their hand/arm, this would be pretty cool.
But since you would have to wave an RFID badge in front of this, it doesn't gain much versus just using your key. - nograz, on 10/12/2007, -0/+1I have been meaning of doing something like this. They had pods that act in a simular way that you can make the door unlock when you are in range.
- tmibiker2, on 10/12/2007, -6/+7security??
I think not

SO HA!! - edrift101, on 10/12/2007, -1/+2Easily cracked and any crime commited in the house will of course be linked to...YOU.
- kinkysexradio, on 10/12/2007, -1/+2Next step: add voice recognition.
"Computer - open door."
Sweet! - nicepants, on 10/12/2007, -0/+1I was thinking more...forget your key/SSH in with your blackberry. At least it would impress my geek friends on a late-night drunk stumble back from the bar. It would also be nice when I have a friend meeting me at my place, who shows up before me. I could "buzz" them in until I get there.
- Kodiak41226, on 10/12/2007, -0/+1That is pretty awesome, but I'll wait until I can pick it up at Home Depot before I count on my crappy electronic project skills to protect my house.
- edmcguirk, on 10/12/2007, -0/+1Wouldn't it be easier and cheaper to modify a keyless entry kit from a car? Or hack a wireless doorbell? Why do you need to get a PC involved?
- abbtech, on 10/12/2007, -0/+1Cool project. Looks like it isn't for the faint of heart, there is lots involved to get it to work. The article is nice and detailed though!
--------------------------------------
http://hackedgadgets.com - DeathonWheels, on 10/12/2007, -0/+1I had this idea for my final EE project. Guess I'll have to think of something else or a better way of doing it.
- RadiatedAnt, on 10/12/2007, -0/+1This is just plain retarded. Did you see the huge gaping hole he made to the door?! the only thing that is covering it is a flimsy plastic rfid box... Burglers would have a nice laugh, "thanks for drilling the huge hole above the doorknob, saved me alot of trouble"
- ChristNewsWatch, on 06/04/2008, -0/+1The second beast also forced all people, small and great, rich and poor, free and slave, to have a mark on their right hand or on their forehead.
No one could buy or sell without this mark, which is the name of the beast or the number of its name.
This takes wisdom. Let the one who has understanding find the meaning of the number, which is the number of a person. Its number is 666. - Bandito, on 10/12/2007, -2/+2RFID Tags? For my house?
I have two words for you: Buffer Overload
And two more words: No thanks. - jamesmar, on 10/12/2007, -0/+0i got an idea...dont have anything worth stealing. hahahahahah :o)
- godspeed1074, on 10/12/2007, -0/+0i just wantone that i can attach to my dog, his doggie door will open when he walks up to it, and the cats wont get out
- kabayashi, on 10/12/2007, -0/+0Has anyone successfully done this? If so, how long did it take you?
- Kazrog, on 10/12/2007, -1/+1True, locks are fairly easy to pick. I need a persistent webcam with remote friggin lasers installed on my house.
- barstool, on 10/12/2007, -0/+0Considering the price of all the parts, and hackery involved, the mykey 2300 seems like it would be a whole lot easier. Cooler looking too :) Plus, if it runs out of batteries, it has a terminal for a 9volt outside, so you can still power it up,swipe your tag/enter code and let yourself in.
- sinembarg0, on 10/12/2007, -1/+1lol a few minutes thats a good thing. at the defcon conference, they have lockpicking competitions. the record is under 10 seconds. a few minutes is good. i am a lockpicking newb (read ive done it 3 times) and i can do it in like 4 mins with the right tools. locks only keep honest people honest.

...Or been in a long term relationship (read 5plus years) with a woman. - clownguyx, on 10/12/2007, -16/+10Or you could just install one to the bedroom to keep the wife/girlfriend out while surfing questionable sites.
- PecanHead, on 10/12/2007, -17/+3oh *****, hadem, that's funny
