Sample Sources: Fingerprinting

This article will explain Fingerprinting and its uses 

Background

Fingerprinting refers to the Digital Fingerprint of a respondent. Turning on Fingerprinting will block a machine and/or ip address from being able to take a survey multiple times across all Sample Sources. You have the ability to turn on Fingerprinting for any and all Sample Sources. You can even exclude specific Sample Sources as well. Fingerprinting checks will happen across all Sample Sources that are toggled on. 

Accessing Sample Sources

Follow the steps below to turn Fingerprinting on or off. 

1. Click on 'SURVEY SETTINGS' on the left side of the question tree
2. Click on 'SAMPLE SOURCES' 
   

Turning Fingerprinting On/Off
