Integrated Fingerprint Reader
|
Integrated Fingerprint ReaderIBM released a second generation of T42 models in autumn 2004 featuring Intel Pentium M 765 processors and an integrated fingerprint reader. The fingerprint reader is produced by a company called UPEK, which is specialized to fingerprint readers. It seems to be integrated as a USB device. Furthermore, IBM states that there's an interface with the Embedded Security Subsystem. |
Linux Support
A closed source driver from the vendor has been released. It interfaces to the hardware as a user-space USB driver through /proc/bus/usb and provides a BioAPI 1.10 device, which can then be interfaced to pam for authentication by user programs. The driver can be downloaded from http://www.upek.com/support/dl_linux_bsp.asp; see the according HOWTO for detailed instructions.
