The files index.html, js/sha1.js, and js/fingerprint.js are submitted as a draft proposal for TY2014 filing season for the implementation of browser-based tax eFile solutions.

Rev. date 12/11/2014

To execute the code for testing purposes, simply double-click on index.html to open the page, which will automatically execute the javascripts to provide a DeviceID (SHA1 hash) and will also display the system components used for generation of the browser fingerprint.

The purpose of this code example is for tax return preparation software vendors to integrate the fingerprint generating portions of this javascript code into their online browser-based solutions for TY2014
