Brian W Posted February 17, 2009 Share Posted February 17, 2009 I'm working on a CAPTCHA system and would like some feedback. http://70.167.219.180/test/Captcha.php?Chars=6 $_GET['Chars'] can be between 5&50 (try 50 :-) for testing. Security includes: characters are random from list A-Za-z1-9 (besides i and l) each character is randomly 1 of 4 fonts (Arial, Times, Courier, and "IrisUPC Bold Italic") characters are slanted at random angle between -30 and 30 all entities are randomly colored with text being slightly darker in nature curves and thick lines behind text and thing lines in-front of text Is this a good CAPTCHA for serious use? I;n open for suggestions... Thanks Quote Link to comment Share on other sites More sharing options...
nrg_alpha Posted February 17, 2009 Share Posted February 17, 2009 Something tells me this should be in the 'Beta Test Your Stuff!' forum. Quote Link to comment Share on other sites More sharing options...
Mchl Posted February 17, 2009 Share Posted February 17, 2009 You could also remove O and o. They're hard to distinguish while distorted. Quote Link to comment Share on other sites More sharing options...
Brian W Posted February 17, 2009 Author Share Posted February 17, 2009 Woops, didn't notice the "Beta Test Your Stuff" board. sorry. Got to "Critique" and thought I was in the right place. I'm not being case sensitive at the moment so O and o will work the same. does case sensitivity add a whole lot of extra strength? Quote Link to comment Share on other sites More sharing options...
