Project Description

The EFF has developed a method of identifying the uniqueness of a browser configuration. An example of an implementation of this methodology:

[url removed, login to view]

This project is to replicate the EFF's implementation of these browser metrics in simple Javascript functions.

EFF's PDF on the subject may be viewed here:

[url removed, login to view]

Values returned:

Functions will return the plain-text value from the EFF column entitled 'value'.

Additional Requirements:

* Only standard Javascript may be used; no jQuery or libraries that must be included. IMPORTANT!

* To demonstrate that you have carefully read over the specs, please include the phrase "I have carefully read through your project requirements 3 times" in your bid.

* Any code submitted must also be mobile-compatible with at least iOS5, Android, Windows Phone 7.

* Any code submitted must be cross browser-compatible with at least IE7, Firefox 17, Chrome 23, Opera 12, and Safari 5.1.

* Each fingerprinting metric will have a separate function, which can be called independently of other functions in the script.

* An additional general function will also need to be created to translate passed values to a MD5 hash. Each fingerprinting function will call this function to return a hash of its plain-text value.
