Press Enter once again to log-in (or to rescan your finger)

In the log-in screen press Enter and scan your finger.

p84530.tar.Īnyway it is working out of the box now but with only two drawbacks,

u_18.04.md except I downloaded latest validity sensor file form original HP's driver site.

After many attempts I was able to successfully install all necessary drivers for it and make it working. The device is Validity VFS495 (138a:003f). You can enroll your fingers by using the fprintd-enroll utility or from UI using unity-control-center user-accounts in unity or gnome-control-center user-accounts in GNOME (it's the same as going in System settings -> User accounts pane and enable the fingerprint login).I'm running an old HP probook 440G1, which has fingerprint support.

If you're using ubuntu just use this PPA to get the libfprint TOD packages with vfs0090 sensor support.Īlso, in the ubuntu (and derivates) the code that you will use will be based on the tod submodule. Unfortunately there's currently no easy way to implement this in this driver without reverse-engineer the fingerprint template creation that the windows drivers does in host.

This unfortunately can't be done in 138a:0090, but you can still use a Windows installation (even in VirtualBox) to enroll the prints to save them in the chip and enable the match-on-sensor, this can make the verification faster, safer and higher quality. This is the only supported way by 138a:0097, so once you've enrolled your fingers with validity-sensors-tools.enroll you will be able to re-enroll your fingers in fprintd to use them in linux as well. Sudo validity-sensors-tools.enroll -finger-id # This is needed and only works in 138a:0097: Sudo snap connect validity-sensors-tools:hardware-observe Sudo snap connect validity-sensors-tools:raw-usb I recommend using the validity-sensors-tools/, you can install it in any distro as snap, or you can use it manually from sources located in my python validity fork You can test it using the examples or just using fprintd-* tools (GNOME supports it natively from control center).

It uses libfprint image comparison algorithm, we might move to in-device check later.

Here enroll, verification, led and all the operations work.

Most of the device interaction and crypto code is coming from the prototype, so basically it needs lots of cleanup, but I hope to rebase this on the code from python-validity.

This version works only with fprintd2, if you still use fprintd see the old version.

Alernatively, but it's less secure, you can use a Windows installation with VirtualBox (sharing USB) guest or with a Windows installation in bare metal.

It only works if the device has been initialized using validity-sensors-tools/.

Thanks to the amazing work that nmikhailov did in his prototype and uunicorn in python-validity and synaWudfBioUsb-sandbox, I spent some time in getting a libfprint driver for the 138a:0090 (and 138a:0097) device up.
