Digital Fingerprinting / Forcing respondents to only access survey once – General email reply back to customer


One item you may want to enable for the web surveys is cookies to help track respondents. With regards to cookies, take a look at the Survox Javascript_jquery.doc documentation specifically the “initial_jquery.js” section starting on page 6 as there is information on how to enable cookies. You can obtain the latest Survox JavaScript/JQuery documentation from the Survox Solutions articles by searching for “

JS File Changes/jQuery Functions/Latest JS files/Demos”.

In your spec/QPX shell, you can use a combination of IP address (SPC,I,A I think is the question type) with numeric quotas and perhaps cookies on the index page to try identifying a unique respondent and it will work most of the time, but both options allow for exceptions – cookies can be easily disabled and IP addresses are dynamic and/or shared, so it’s helpful but obviously not foolproof.

Truedigitalfingerprintingadds an extra ‘layer’, by relying on 50+ pieces of data (browser, OS, etc) combined in a way that creates a unique ID for each respondent by machine, so you’ll want to clarify if that’s what you really want. You would either have to design something like that in-house or work with a 3rd party for truedigitalfingerprinting, in which case it has done via redirects, like you would do with a panel company.
