Re: Validity Fingerprint Reader Linux


@CBHedricksAgain - to get traction on this - get on the phone and file an official complaint.

This has not worked for me. Through the official support website, whoever I managed to get in touch with, declared not responsible for such software issues. They pointed me to this forum instead, as the only available channel for such things.

Re: Validity Fingerprint Reader Linux

NO... they don't s**k - they're too lazy to do even this...

the only thing they need to do - share specifications or if NDA is a problem - make a proprietary version of libfprint

 

no comments -_-

The issue is not from NDA or any part of the software. The issue is, current model of FP reader uses on chip verification and acts as a FIDO device. Libfprint need vendor's certificate to decode messages from FP reader but this certificate is not possible to get.

 

The situation is very similar to VLC video player's Bluray certificate. While most bluray player vendors can get certificate from movie company so people can play disc. But VLC, despite it is just another player, cannot get certificate so it cannot play most of the bluray discs.

Re: Validity Fingerprint Reader Linux

If the situation was similar to VLC - there will be some unofficial but fully working methods (you can make vlc play encrypted blu-rays, just find a file with keys, library libcss is aleready existing)... if certificate only - just pull it from official driver, but 06cb:009a  (T480,T580,X380,X280) sensor is a match-on-chip.. it's more secure, but also it does not send image of fingerprint to libfprint (no backwards compatible) ... so we need not a libfprint modification but a completely different piece of software.

Re: Validity Fingerprint Reader Linux

A small addition:

a friend of mine said that these fingerprint readers are not readers at all...

 

it's more like USB token / smartcard, where PIN replaced with a touch of a finger..

 

maybye try to use libraries that work with smartcards than frankensteining togehter some kind of a libfprint for a match-on-chip ?

Re: Validity Fingerprint Reader Linux

My T480 has a synaptics 06cb:009a fingerprint reader which is apparently not working in the Validity reader yet. I expected better linux support from Lenovo. Community support should not be required for the drivers for hardware Lenovo has chosen and for a problem persisting for several years. That said, I applaud the good work of the Validity collaborators and look forward to a solution soon.
