I discovered that anyone have yet to discuss HEC's. So I thought I might as well start this topic. HEC stands for "HTML Encoded CAPTCHA". It's quite easy, it is using means of HTML and CSS to create the image which was originally broadcasted in png/jpeg/gif or perhaps even svg.
It is just about being creative. I know what you're thinking. Usually you would at maximum send 3 bytes per pixel, but now weren't going to send like fifty time as much! Yes, it is a waste of traffic, but it has a large security scale I should imagine. Anyway, here is a HEC, I created: http://sviip.dk/tut/captcha.php And its source: http://sviip.dk/tut/captcha.phps Note: I already created the code for an image, I use on another site - where it is actually png, because I don't require that top notch security. Conclusion: I would say it has its advantages, but I fear its disadvantages are too large over its advantages. Only use it when spambots are on your door step every second... and if you can afford the extra traffic.
