Dear all,
I'm submitting the AES3500 driver for peers to review.
The AES3500 is a pretty old fingerprint device produced by AuthenTech. It
possesses a *press-typed* sensor of dimension in 128x128. Which is
similiar to AES4000, except the later is in 96x96.
The driver is a deriative work of Daniel Drake's AES4000 driver, with a
few parameters tuned for AES3500. While there seems no problem scanning
fingerprint images with it, the verification rate is pretty low at the
moment.
The AES4000 driver performs badly as well. As you've commented, the
likely problem is that only a tiny area of the finger is sampled.
I imagine the windows driver (where the sensor seems to perform OK) has
a fingerprint processing engine heavily tuned to small amounts of data.
It's probably quite insecure as a result.
Thanks for the contribution!
Daniel
