Hi Sebastian, I am just referring s per windows implementation here. So the user may try to enroll the same finger several times and since the templates are stored in device(Not the host) it may run out of memory. Hence this duplicate check is necessary for those devices which stores the templates in device memory itself.
The other thing is you need to provide an API in the libfprint to do the duplicate check when enrolling a new finger. So this command goes to the device all through and device itself sees whether the finger is already enrolled or not. Depending on this output further enrollment process can be continued or a warning message can be displayed(As in windows). You can refer the windows WBF API's for the same. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1882878 Title: The user panel let you enroll the same finger several times Status in gnome-control-center: Unknown Status in gnome-control-center package in Ubuntu: Triaged Bug description: We are able to enroll the same finger for all 10 available options. (No error like 'Fingerprint is already enrolled' is observed). In windows it doesn’t allow to enroll the same finger, it has a duplicate check API. Here we have all 10 finger options are shown in GUI itself, so whichever finger is enrolled atleast the same finger can be grayed out so that user cannot enroll the same finger again.
