This is the project focusing on creating Linux driver for Egis Technology Inc. ID 1c7a:0570 fingerprint scanner (also known as LighTuning Technology Inc.)

All work is stopped, see Current state for more information.

• libfprint/: libfprint repository with driver integrated
• logs/: usbpcap logs of Windows driver
• scans/: fingerprint scans

Files in repository root contain some source code for playground purposes.

All general functions are ready, driver is succesfully integrated in libfprint, but there are some problems with matching algorythm.
Seems like matching algorythm used by libfprint can't work with data from this device. The scan area is too small to detect enough minutiae.
It is possible to try to work with it as a swipe-type sensor, but there is no guarantee and I currentry unable to do this work.

If someone wants to try finishing my work, feel free to do it. Contact me if you have any questions: [email protected]
