Title:
Need information: Finger print sensor disabled after some incorrect
failure attempts either consecutively or not in sequence with a count
of some number
Status in fprintd package in Ubuntu:
Fix Released
Bug description:
Observation:
It is observed that finger print sensor is disabled after few failure
attempts not in sequence with a count of some number of attempts.
Is there any such count requirement of disabling Fingerprint sensor
for few seconds after some incorrect failure attempts not in sequence
with a count of "X" ?, it is observed failure with below sequence:
WF - wrong finger, CF - correct finger
WF, WF, CF, WF, WF, CF, WF, WF, CF, WF, WF, CF, WF, WF, CF, WF, WF,
CF, WF, WF, CF, WF, WF
I have looked at fprintd service logs from host and didn't observed
any different commands received from host when the fingerprint is
disabled for few seconds.
Need some clarity on behavior of this feature and if there is any
document or link explains the requirements of Fingerprint application
behavior will be helpful in understanding the host behavior.
Kindly let me know if i can provide any extra information.
Thanks,
Prafulla Kota
