Hi,

I'd like to enable face authentication flow as part of Pixel.

I use depth camera and run my algorithm. I would like to make sure my solution is secured end to end.

I started reading on https://source.android.com/security/trusty/ and saw https://source.android.com/security/authentication/fingerprint-hal

but I can't find any data or direction as to camera HAL or face auth HAL and how to connect to TEE etc. (where safe pictures? is camera HAL is part of security flow or another dedicated HAL etc.).
