[edit] Introduction

The upektc driver supports devices based on the UPEK TouchChip chipset.

upektc is part of libfprint and is developed by Jan-Michael Brummer.

[edit] Supported Devices

See Supported devices for more details.

This driver supports the device found in the Samsung P35 laptop. It is also believed to exist in some rare standalone devices.

This driver does not support the UPEK TouchStrip found in a lot of other laptops. Such hardware is supported by the upekts driver instead.

[edit] Driver history

This driver is an adaption of the code found in Jan-Michael Brummer's UPEK TouchChip driver project. These efforts were based on bus traffic analysis from the UPEK Windows driver.

[edit] Device operation

This is an imaging device that returns greyscale images with 208x288 pixels.

[edit] Security notes

See Security notes for general discussion on fingerprint security.

Fingerprint image data is sent unencrypted over the USB bus.

[edit] Other capabilities

This hardware has the capability to store fingerprints on the device. libfprint/upektc does not currently offer access to this functionality, but this will change in future.
