So, this is an issue that depends on device. For MOH (match-on-host) devices there's no other option than doing this, however the images are saved in a place where only root can access, so are safe in a non-compromised system.
For MOC (match-on-chip) this is not the case so the issue is not valid. As per this, I think we can close the issue. ** Changed in: libfprint (Ubuntu) Status: Triaged => Won't Fix -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1818938 Title: Found storing user fingerprints as raw image files To manage notifications about this bug go to: https://bugs.launchpad.net/libfprint/+bug/1818938/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
