When authentication is initiated on the terminal, the terminal will poll the user ID to
external controller. On polling out the ID, the corresponding template (if exists) is
fetched from the external database and is authenticated against user’s biometric on
the terminal. Once the template request is posted to the external database, the
terminal shall wait for the finger template from the external database to start
authentication. Further process shall be same as authentication.
Polling Process using buffer:
The user’s input ID will be queued in the terminal’s queue, which is polled by
external application.
External application waits for the User ID by polling the buffer. After getting an ID,
it will search the template in database and send template to terminal for further
authentication.
The user is authenticated by the external device and granted access accordingly.
MorphoAccess® SIGMA Extreme Series terminal also has distant commands to retrieve
polling buffer status and polling buffer data. Refer to the MorphoAccess® SIGMA
Extreme Series Host System Interface Specification document.
How to Activate?
External database mode can be activated through Webserver > Complete
Configuration, by setting “ucc.enable_external_database” parameter to 1. Only an
admin user can activate polling mode. You can refer to the MorphoAccess® SIGMA
Extreme Series Host System Interface Specification document to know how to set this
parameter.
