We've all seen it: on cops over license plates, on other TV shows over credit card and check numbers, and all over the web over many sensitive areas of documents. Blurring has been a long accepted way of eliminating information. This however, has all changed. A recent dheera.net project proved that these numbers can easily be brute forced by simply clearing out the original blurr, typing a new random number, blurring the new number, then comparing that image to the original.
