Any feedback about howdy

[Luya Tshimbalanga]

I recently packaged[1] an application named howdy[2], a bionic facial
authentication similar to Windows Hello. Laptop like HP Envy x360 have
an Intel RealSense Depth Camera[3] which are currently restricted on
640x480 resolution when running on Fedora 29 using amdgpu in my case.

Will it possible to integrate on the workstation with some improvement?

So, I did have a quick look at howdy the other day.

The low resolution is normal, I believe. As I understand it, Windows
Hello and similar rely on the two separate flashes to create a 3D model
of the face. Windows Hello is actually specified to already work with
320x320 pixels.

Unfortunately, it seems that Howdy simply uses the image into OpenCV
for normal 2D facial recognition. While this approach is a lot simpler
and easy to implement, it is also quite a lot less secure.

I personally think that integrating it would currently give users a
false sense of security.

If you want to integrate it in Workstation you'd need:
- to add support for it to authselect
- add support to gdm's PAM configuration (see gdm-* files in /etc/pam.d)
- add enrollment and "face" management support to GNOME's Settings

You can use the fprintd integration as an example of how this could be
implemented.

But as Benjamin mentioned, the implementation doesn't seem to be currently
good enough to be integrated.

Thanks for the feedback. I will sent the suggestion to upstream so they
can improve their app/
