Overview
In some cases, the customer receives 'INVALID DATA' for the provided multirange liveness records. In some cases, it did not work the first time, but it did work the second time within the same session and browser.
Symptoms
When a binary record from multirange liveness is provided to the DIS server, the response contains an 'INVALID DATA' error.
Root Cause
The problem is a bug in the default configuration on the DIS side. In some edge cases of multi-range liveness, faces were not detected due to the maximum face size value being configured too strictly by default.
The workaround is to change the following parameter: innovatrics.dot.dis.customer.selfie.face-size-ratio.max' from the default value of '0.4' to '0.6' in your application.yml file.
Resolution
Change the following parameter:
'innovatrics.dot.dis.customer.selfie.face-size-ratio.max'
from the default value of '0.4' to '0.6'
Additional Notes
This bug is fixed in DIS server version 1.64.0+
