Fingerprint Recognition with Linux & IBM's T42

Posted by timothy on from the nobody-said-*which*-finger dept.

Michael R. Crusoe writes "UPEK, provider of popular fingerprint sensors to IBM's T42 notebooks and others, has announced that they will be providing a BioAPI compliant library to perform biometric authentication under GNU/Linux. Will Linux be the first operating system to have integrated biometric user authentication 'out of the box'?"

    AFAIK not - fingerprint is just "convert black&white image to curves, find markers (like end of "line", join of 2 lines etc.) and save relative position of these markers. In fact fingerprint "image" is usually a few 10s of bytes!

    I don't understand this. Isn't writing to PAM all you need to do to support authentication on Linux?

    No. For example, the OpenSSH server needs explicit support for GSSAPI to support Kerberos Single Sign On. That could not be done within PAM.
