Cookie found:uid = currently not set
Click to create an evercookie. Don't worry, the cookie is a
random number between 1 and 1000, not enough for me to track
you, just enough to test evercookies.
Now, try deleting this "uid" cookie anywhere possible, then
or
evercookie is written in JavaScript and additionally
uses a SWF (Flash) object for the Local Shared Objects and
PHPs for the server-side generation of cached PNGs and ETags.

// set a cookie "id" to "12345"
// usage: ec.set(key, value)

// retrieve a cookie called "id" (simply)
ec.get("id", function(value) { alert("Cookie value is " + value) });
// or use a more advanced callback function for getting our cookie
// the cookie value is the first param
// an object containing the different storage methods
// and returned cookie values is the second parameter
function getCookie(best_candidate, all_candidates)
{
alert("The retrieved cookie is: " + best_candidate + "\n" +

"by looping through the all_candidates object.");

}
ec.get("id", getCookie);
// we look for "candidates" based off the number of "cookies" that
// come back matching since it's possible for mismatching cookies.
// the best candidate is most likely the correct one
