Captchas

I hope mine isn't I've gone for: Diagnoal Hatched Backgroud (Light Gray) Mixed Upper and Lower (no numberics) Text rotated at -45 +45 degrees (non centered). Steel Blue text. You can choose any number of characters you want to generate and the control is scalable with our worrying on font sizes / spacing etc.

Just finished implementing a Captcha Control in SilverLight... Do you love or loath Captchas?

Did you test it against OCR software? I've seen some that it seems to me could be deciphered by OCR fairly easily. Otherwise, the only time I loathe them is when they defeat my botnets from creating unlimited facebook accounts.

Nope, I reckon you could crack it, but it's not really going to be exposed to the general population, so I'm not too worried about OCR.

Have you excluded letters that look similar whether upper or lower case, and zeros, ones, i, l, o, etc? If you haven't, it's a guaranteed PITA.

Just make sure it is not case sensitive.

Your captcha looks OK. Now c(r)aptchas like this I loath http://www.narnio.com/2010/08/20/leaving-linkedin/[^] X|

Thanks. I suggest you limit rotation to [-30,+30]. is the first letter a Z, a z, or an N? is it case-sensitive? I'd like captchas to be somewhat tolerant, say accepting one wrong or missing character. All to often it is impossible to get them right. :)

They are a fun aside to the day to day grind of business programming. Unfortunately, modern character recognition is very good, slave labor is very cheap, and the baby boom generation has degenerating eye-sight and computer literacy issues.
Need custom software developed? I do custom programming based primarily on MS tools with an emphasis on C# development and consulting. I also do Android Programming as I find it a refreshing break from the MS. "And they, since they Were not the one dead, turned to their affairs" -- Robert Frost

Nope, that for the advice. That would leave only a few Characters.

Speaking personally as a spambot, I have to say I do not approve of them.
