Hi Guy's

Here's a tough one

I need to find a device that i can use to secure access to a fingerprint reader.
Basically what I need is a device that:
1) has a female usb input and a male output with a controller device in the midle
2) once joinced to the fingerprint device it will be epoxied together
3) I want then to be able through software to send a command to the dongle to unlock the use of the fingerprint device

Can anyone point me in the direction of something like this ?
What my company wishes to do is restrict use of the device by any software other than the software that it was intended for.

Solution 1

Connect your Fingerprint module with Arduino. Acquire data through Arduino. Accept a serial command from serial port in Arduino. If the command is equivalent to some code, enable the Fingerprint module.

You can check my following tutorial for PC+Arduino+Fingerprint module interface.[^]

I am not sure what Fingerprint module you have, so if it is R305 or similar, the above link might be helpful to you.

My Device is a digital persona, Good solution but i am afriad it wont suit my needs I need a more out of the box solution becuase I need to roll this out to thousands of devices.

If you are using Digital Persona, then it comes with a driver. Every driver puts a registry entry. There are some simple Win API method which can detect when a USB device is inserted. You can compare the device ID and use some password to activate the device.

However if a hardware lock is so important, cant there be a USB hub? Logic remains same. Alongside the device you provide a USB stick and embed it's ID into program for password checking. However if such a solution needs to be distributed in lot then software lock might be best option?

yes but that wont prevent the device from being unplugged and used in a diferent pc.

Basically what it boild down to is we want only our software to be capable of using the device, I am checking with securitech if they may not have a solution for us.
