I was told an interesting story about those wavy word pop ups you see all the time on most websites a few days ago.
Apparently they are not a security feature but part of a massive world wide attempt to use the mass public to help fill in the odd words that text recognition software has trouble with when converting old books, documents, and typeset text into modern electronic media.
Being that very old documents and books where printed one at a time with manually set letter blocks it was common for the text to shift around from one page to the next as it was being printed.
Plus being that they where often pushed into the paper a bit too hard at times creases would occasionally form and some text would end up being printed over a crease and cause a splitting of the letter or letters near by.
because of these shifted letters, faded letters, blurry letters, and physical anomalies text recognition cant accurately recognize the individual letters and translate them. It can only identify that there is a word there.
That selected mystery word block gets sent to a master data collection system that in turn sends that word out to the sites that have that wavy word pop up and when someone reads it and types in its assumed correct spelling it is then sent back to the data base and used to fill in its formerly missing spot in the sentence of what ever book or document that it related to thats presently being converted.
Way cool!
