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 https://forums.phpfreaks.com/topic/145596-capcha/ 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 https://forums.phpfreaks.com/topic/145596-capcha/#findComment-764394 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 https://forums.phpfreaks.com/topic/145596-capcha/#findComment-764396 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?
