Form security using a simple maths question

    Asked on December 10, 2014 at 04:10 AM

    Hi - I have been asked to remove the Captcha on my form as it is not accessible. I tried using reCaptcha but it was awful.

    Is there a way I could add a field that says 3+4= (or similar) and only allow the form to be submitted if the answer is correct?

    Unfortunately that would not be possible unless you were to take the jotform's source code and implement the check if the users entered response matches the value in the another field (this currently not being possible in Jotform).

    As you can see in this quick sample:

    We can make it change signs and show the calculation that the people should make, as well as calculate what should be entered, unfortunately checking against another field is not possible (without source code implementation).

    Now since we have several different captchas I would like to point them out as possible alternatives for you to check:

    Drawing Captcha

    PlayThru CAPTCHA

    Roll Dice

    Tic Tac Toe

    These are next to the standard one that you have mentioned to have already been using.

    Do let us know if you have any further questions.

    Best Regards,

    Is this available yet?

    It's a good method and I'd like the option.

    Can I feature request this please?

    Hi Randy,

    Thanks ... but here are my thoughts after reading that.

    That'd be great if I had about an hour or so and wanted to use a hack job with loads of conditions and hidden fields. I don't

    It's like killing a mouse with a sledgehammer.

    Quite simply ... jotform ... a great tool does not offer this most effective form of spam security as a widget or field. It is commonplace in many wordpress themes.

    There are, however, other mind-numbingly useless captcha offers that are either completely ill thought or don't work properly. Recaptcha was one of the worst things I've ever seen on a form.

    In jotform's opinion what is the most effective form of spam secuirty that it offers ... what would you use grade4pagasa

    It's got to be easy for the user ... cpatcha, recaptcha ... forget it ... they're a nightmare

    Thanks Mark

    Hi Mark,

    How about Google reCatpcha widget: You just put a feedback on recaptcha, but this one is different from the reCaptcha in the Form Tools section. Maybe, you should try?

    As for the match captcha or Arithmetic actions for Captcha, I have submitted a new ticket for that and informed our widget team about it. 

    Thank you.

    Thanks Welvin,

    Please update on the arithmetic function on this thread. I have cited Google Recaptcha as the best option. Looks good.
