IBM Integrated Fingerprint Reader

Integrated Fingerprint Reader

IBM 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 specializes in the manufacture of fingerprint readers. It is integrated as an USB device, and does all the matching in hardware, making it rather easy to use. Furthermore, IBM states that there's an interface with the Embedded Security Subsystem. UPEK now sells the fingerprint reader as a USB peripheral bundled with the same underlying software for accessing password-protected online accounts and Windows: Eikon Digital Privacy Manager

Open Source

There is a new GPL driver at http://thinkfinger.sourceforge.net; see the How to enable the fingerprint reader with ThinkFinger for detailed instructions. This is the recommended option as it integrates more seamlessly with PAM and doesn't produce a tacky graphical prompt.

Binary Only

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 corresponding HOWTO for detailed instructions.
