Car Start on Finger-Print Recognition?

tyRion · 05-28-2005, 03:33 PM

Would it be possible to do this?

Either 1) Wire a Finger-Print scanner to the pc, so it only boots if a fingerprint is picked up, then start the car, via a line out(LTP?) to a relay, would mean PC would be on before Car PC

Or 2) Wire the scanner to the relay for starting the car directly, then the PC boots like normal

In the first case you'd need a button to start the car, but in the second one it'd just start when the print was recognised.

These sites may be helpful, Print-Readers or Bio-link U-Match

Edit: I also just found this, which may be of some use, considiring it dosent need the PC to be on

Try searching the forums with terms "fingerprint". There's a big thread on the MS fingerprint reader there.

problem with going straight from the scanner to ignition is that you would have to have a dedicated system. one idea is that there are scanners for home doors that controll relays to unlock the door. you may try something like that and just run the relay connection to the ignition. personnaly id just run straight through a computer with biometric login and a startup program signaling relays through one of its ports.

Ok, I wrote a program to put on the CPU of the UniFinger™ SFM3000.

Its written in BASICA or GW-BASIC which is the only code I know off by heart, here it is, please point out any mistakes

Code:

 10 if in5<>1 and in4=1 let x=1 else let x=0
 20 in in1=1 and x=1 let y=1
 30 if v=1 let y=1
 40 if x=0 let y=0
 50 let v=0
 60 gosub 170
 65 if in3=1 and in2=1 let y=0
 70 if y=1 and in2=1 goto 90
 80 goto 10
 90 let y=2
100 let v=1
110 for w = 1 to 50
120 if in3=1 goto 10
130 next w
140 gosub 170
150 let y=1
160 goto 10
170 if y=0 let out1=1 else let out1=0
180 if y=1 let out2=1 else let out2=1
190 if y=2 let out3=1 else let out3=1
200 return

Here are the varibales and inputs I'm using (you can use 8, which i have 5 in, 3 out, though out1 is probabally unnecissary)

Code:

in1	Thumbprint Match signal
in2	On/Off PTM stitch
in3	Engine running sensor
in4	Drivers Door PTM (Closed gives value of 1)
in5	Alarm Indicator singal (1 is alarm on)
out1	Off
out2	On/Drive
out3	Ingition
v	Remember ignition position from loop
w	loop
x	Door and alarm OK
y	Key state

The line ins or outs may have to be linked to relays or optoisolators

just remember to take care of your thumb... if someone cuts it off they can run away with your car

we will need to keep a spare thumb ;-)

actually, you can bypass the fingerprint biometrics with a gummybear.

It would be proably be best to use an aftermarket car remote start system. There is more to starting most cars then just the ignition wire. Many remote starts can be activated with a neg pulse and that would cover all the relays, safety shut offs, starting and stopping the car.

emdzey01 · 06-21-2005, 04:03 AM

gummybear? ill have to try that out sometime.

and yeah, you should keep spare thumbs in your wallet, just in case you leave yours inside your car.

Hello,
look what i found...fingerprint to start cars..
visit www.automobile-security.com

Looks real..
what do u guys say?

PRetty cool. It appears to be a remote start and/or keyless entry that uses a fingerprint reader instead of the traditional remote on a keychain. Their mounts are pretty ugly, though.
It also doesn't have a full-fledged PC that's on all the time sucking your battery down to the point of inoperability.

It sounds cool but after working with biometrics in a hospital primarily for medication security, there is no way I would use biometrics to secure anything I wanted to reliably access. I'm sure there are overrides, but the failure rate of the hardware (the biometric reader) is horrendously high.

It's great when it works but a PITA when it does not!

Any bad guy who has seen the movie "Demolition Man" is gonna get ideas...

the new lexus ls400 has fingerprint recognition, but i think it only unlocks the car.

spammer!
