Fingerprint Entry System!

Well, after a few months of working on my project every waking moment - its finished.

A valid fingerprint locks and unlocks the doors, flashes the parking lamps and it even has a red security flashing LED. There is also a low battery indicator and a trunk open option. The system also flashes parking lamps and stuff when the interior lock switches are used. There is also a horn output. For security purposes, the print can only be enrolled when the doors are unlocked with a key switch. Now, I can graduate!

The picture shows the door that conceals the sensor, and 3 indicator LEDs. It looks red, but it is actually orange in person.

Here are some more pictures...

I used a microcontroller for most of it - programmed the scanner with a computer.

With the scanner door closed, there is a switch to shut it off and save power. The scanner automatically detects a finger - which has to be alive in order to be valid. There is also a small heater on the inside when it gets below 10 degrees.

Look just to the left of the handle. If you look really close, you can see the outline of the print reader door and three little holes.

Here is the box that would sit under the seat.. or somewhere. its about 4"x4". The large squares are relays to control the locks, lamp, horn, and trunk. The trunk opens if the door is locked and you scan your finger to unlock it twice within 6 seconds.

The sensor completes a circuit with the skin's live layer underneath the surface. Some other scanners even check body temperature, pulse, and blood oxygen level, but they werent available at the time.

The only problem with selling these is that Purdue owns part of it since i developed it for a class. That, and the installation process is a pain. It would be easier to have these be original equipment.

does the scanner send out a unique code for each fingerprint, and the microproc have stored ones in memory to compare it too?
thats great, im an EE too.

ohohblita:

The scanner has a DSP connected to it. The DSP board processes and stores the fingerprints in memory. 200 prints can be stored to be compared with a newly scanned print. The microcontroller processes a verified print and controls the LEDs, locks, etc. To enroll a print, RS232 communication between the microconrtoller and DSP board is required.

That is cool but if someone wants to get into your car they will just break the window, use a slim-jim, or *now* cut your finger off.

very nice indeed; now if you can work that box into something smaller and more practicle and keep the validation for something inside the car such as the starter or whatnot that would be excellent.

either way, until you can control the car from a distance away i'm not impressed...........






j.k. very nice work; something i would love to see in action. good job! :hail:

That is really awsome work.
Did you put the reflector/lamp in the front bottom of the door, or did you find some really rare door somewhere?

'87FAKE-IROC-Z: I put the lamp in myself. Its amazing how many times I have used my Dremel in the past few months.


Kandied91z: My next step would be to have fingerprint ignition - then having a key would be nearly obscolete (except if the battery dies). As far as making it smaller, that could easilly be done - probably half the size.


WS - 666: They could cut your finger off.... except they would be pissed when it didn't work - the finger has to be alive.


DABE: I spent quite a bit on the prototype, but that includes the door and all of that. If i were to mass produce them they would be from around $350-$400.

SuPeR SpOrT: you can't get it... yet. and it would probably be from $350 - $500.

theSteve: The system works like any keyless entry system.

-Two parking lamp flashes (and horn honks) when it is locked, one (of each) when unlocked.

-Flashing red 'security' LED when locked.

When scanning, the LEDs indicate the following:L

-Flashing Yellow: finger present; scanning
-Solid Yellow: finger scanned; remove finger
-Solid Green: print is valid; unlock or lock doors
-Solid Red: print is invalid; try again, or enter your finger into system
-Flashing Red: error/timed out

As an added feature, the yellow LED will flash when the battery is below 9V.

Man, thats really impressive. If you could sell that to the OEM and/or aftermarket companies, you'd be rollin in the dough. I'm not calling this ****, but could you imagine if the ***** comminuty got ahold of this, pretty much a guaranteed best-seller, lol. Now, design a system similar to the Mercedes SL500 ignition.... Proximity Card...

Have you done any sort of patent search yet? Any work towards patenting your idea? I'm not sure what the policy is up there, but I believe that we can petition to have our intellectual property released to us upon graduation.

Nice work. Must have been loads of fun.

One suggestion if I may, for future iterations: I might have put the reader under the door handle. I can't tell too well from the pictures, but it looks like you stick your finger into the recess and press downward? What about mounting it to the door under the handle to where you press upward. That would serve two purposes: 1) combine the actions of unlocking and opening the door into one smooth action 2) it would further shield the reader from the elements and curious kids.

Pretty cool stuff.

MikeS: I was thinking that I would just improve the design enough to make it different - things that if I had the time and experience I would have done in the first place.

86IROCNJ: I'm thinking of ways to make the installation easier... but right now, that is the hardest part (atleast when the door is attached to a car)

Jza: My original plan was to put the sensor under the door handle. I couldn't get the sensor that I wanted, though. If I can get that sensor in the future, it will be under the handle and be more rugged.

I'm happy at all of the responses to this. It really makes me think twice about getting it patented and sell it.

omnipotentgoku: even if I did work for mercedes, I would still have my third gen

Very cool. I'm a sophomore in EE and am nowhere near that level yet unfortunately. I really like the idea but I don't believe it's practical. I wouldn't think it would be any safer than a normal keyless entry/power lock system. If someone really wants to steal a car a fingerprint lock will not stop them. Fingerprints are now pretty easy to replicate. There was something about it in the news a few months ago about a guy in Japan having an incredible accuracy rate forging fingerprints. I still really like the idea though. Definitely worth an A if I were your professor.

Ok I didn't read the entire thread but damn, was that an EE senior/graduate project or something? I'm really impressed. I would like to go into that so much but, I'm like retarded when it comes to anything mathmatical so that pretty much rules it out.

wow.. ok is that 500 per door, or for it all around.

that is beautiful. i give you credit, and i could hope/wish, you could create the Tech Document from hell for this setup. i can garentee you would have 100+ pm's about this. very nice man. very very nice.

IROC57TPI: unfortunately, storing that many prints and keeping them updated would drive the cost up by a large amount and be a pain

soulbounder: Actually, it is near impossible to replicate a fingerprint with this type of system. I can se replication possibly with an optical system. Do you know how exactly they were doing it? Also, the software in my system verifies and stores the entire print - all of the ridges, not just seven or so points on the fingerprint. I would imagine that with the sensor I would get if i produced these (recognizes pulse, body temp, and blood oxygen level) it would be easier to just break the window.

That brings up your next point. Nothing is more secure than the strength of the glass. Keyless lock systems can be faked much easier than a fingerprint. You would just need to figure out the frequency and the data sent. To break into the fingerprint system, you would have to know whose car it was, which finger they had programmed into the system, and then somehow fake it. Not worth it in my mind. I don’t think it would be worth anyone’s time to break the system for stealing a car – then again, you never know.

Also, one of my goals was convenience. Never get locked out again, don’t carry bulky keys or keyless entry fobs around, and don’t worry about losing your keys... That would almost sell it more so than the security thing. Of course, this all depends on the reliability of the battery... and fingerprint ignition to make keys just a backup.

HamSpiced: It would be $500 for one door. If you wanted sensors on additional doors, it would be between $150, and $300 per door (the price of the sensor).
