"Case in point: evercookie, an open source JavaScript API by developer Samy Kamkar. When implemented by a website, evercookie stores a user ID and cookie data in not two, not three, but eight different places—with more on the way. Among them are your standard HTTP cookies, Flash cookies, RGB values of force-cached PNGs, your Web history, and a smattering of HTML5 storage features....So, when you delete the cookie in one, three, or five places, evercookie can dip into one of its many other repositories to poll your user ID and restore the data tracking cookies. It works cross-browser, too—if the Local Shared Object cookie is intact, evercookie can spread to whatever other browsers you choose to use on the same machine."
Tor is a software project that helps you defend against traffic analysis, a form of network surveillance that threatens personal freedom and privacy, confidential business activities and relationships, and state security. Tor protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world:
Will organizations that cloak themselves in privacy contracts be made irrelevant, by the ones that do NOT?
Will we trust opaque organizations, in the future?
Why do we trust them now?
What isn't mentioned here is that, often times, people can make these things quite clear and obvious and provide a ton of proof, ... ...and it STILL has no effect!
