Math Captcha Feature Needed

  • Profile Image
    Asked on November 16, 2015 at 07:28 AM


    See this math captcha 

    It is quite simply the most user-friendly and best captcha system available ... and you haven't got it !

    How do I know? Because, I want to provide all my clients with a simple contact form that has spam protection.

    And with Jotform I can't do it ... without affecting the user experience ... annoying my client etc.

    It was requested here: before the financial crash!

    The options?

    Captcha ... doesn't work ... people can't read it i.e. the client. Can't be bothered to explain. Check this:

    Recaptcha - disasterous ... put that on a form you're going nowhere ... but your clients might to a supplier who has common sense

    Google Recaptcha ... quite simply does not work on all devices/browsers using jotform. This cannot be negotiated with clients. Want to know more? ... here's my post ...

    Loose and strict checks ... they have serious drawbacks I'm afraid .. I am not comfortable using them or explaining them to clients.

    So ... with jotform ... incredibly I find myself in a position struggling to offer a spam protected captcha form.

    I'm thinking of adding a calculation that never changes ... as a frontline spam protection thing.

    Is there a hack I can use with the maths formula field?

    Lastly ... can you implement a math captcha please.

    Or ... advise me on a user-friendly jotform captcha system that works universally

    Thanks Mark

    Thanks for your very detailed input, thoughts, and suggestion about adding " Math Captcha " as an option for use with jotforms.

    For the thread you found that had requested this some time ago I believe wasn't beneficial enough possibly at that point in time though we did leave it marked as open as a future possibility.

    However, I just so happen to completely agree with you about this and that it's a must especially in this day and age where you can never have too much protection for your forms! 

    As you know already we can't promise and time frames. But I'm fairly certain that we might be able to make something happen for this at some point soon as our devs get a chance to consider it when they have time so I've gone ahead opened your new thread about this here as a feature request for it on your behalf.

    UPDATE - I have good news! I've managed to devise a workaround solution for you which will hopefully help you for the time being until our Devs can consider implementing this sort of thing as a possible new feature.

    Basically what I've done is created 3 Number Fields with 2 Random Value Generator Widgets that feed Two Random Number Values into the First Two Number Fields. I then used a Form Calculation Widget to calculate the Sum of the Two Random Values in advance.

    After that I created the related conditional logic (see second screenshot below) with 2 Conditions for each Random Value Widget to Update and Insert those values into the Number Fields. The 3rd Condition is to check and Show|Hide the Submit Button accordingly.

    Additionally, I also hid the Random Value Generators and the Form Calculation from view on the form so the user can't cheat by looking at it.

    Now if the Entered Value of the Third Number Field marked as " =? " input by the User doesn't match the conditions used for the Sum in Form Calculation then the Submit Button will remain Hidden.

    Demo Form:   [CLONE ME!]

    Thanks Kade JM

    I greatly appreciate your time and effort.

    I'll give it a whirl when I'm back on it.

    Many Thanks

    UPDATE II - Hey Mark you are very welcome and no problem we will anticipate your feedback.

    Additionally, I just wanted to give you a heads up that my colleague gave me a reminder about another older thread found from back in July of this year which I unintentionally forgot about and I apologize about that.

    Anyhow, it is very similar to my recent workaround above for you but this one uses a different workaround method to do this within the same field without the usage of too many fields and no widgets in case you want to try it out or like it better as another alternative.

    You can view it here - ("math captcha" tag added to find it easier)

    Also, I would like to inform you that our Widget Team has added your request to their features list and you will likely see something of the sort available as early as the beginning of next year possibly depending on our devs existing workload around that time.

    can I ask whether this fucntionality exists yet ... as a client of mine has stated that the anti-spam drawing widget is sub-standard.

    All the spam methods you have seem to not work very well.

    Have you put a simple calculation anti-spam field in place yet.

    Many Thanks

    Regards mark

    Currently we do not have this verification widget available. 

    Please do note that features may take some time to be available, it is based on the number of users requesting the same. 

    The only verification widgets can be found on this link:

    I thinks this widget may help you to reduce spam too: 

    You may also follow the workaround given by KadeJM above in the meantime, if this feature comes available, we will let you know.

    Hi Kevin,

    I've been around on Jotform for many years. I do not believe the excuse that features are based on number of users. Its simply not true. Either that or every suggestion I make ... is not required from any other user ... and I simply don't believe that. You basically shelve features for large projects like a UI interface reddesign ... or bringing in the ill-fated/ unusable form designer. Stuff like that.

    Respectfully ... the widget you request ... on scrutiny ... is about as practical as a truck load of dead rats at a wedding. I bet you my entire fortune you've never personallu used it in your own business where it matters ... to get leads. Never! There's me suggesting a simple maths captcha ... and you propose a method whereby the recipient has to get an email and paste a code ... naaahh. Garbage in this modern day. You'd lose respondents by the truck load.

    Kade's workaround ... there are problems with it ... but I haven't the time to tell you about them.

    The bottom line ...


    I've tried them all ... and they either don't work ... or are too hard for respondents to manage.

    A simple captcha ... you still haven't done it.

    See this:

    A simple math captcha ... and they don't even create online forms ... you have for years ... but still haven't added it.

    I don't know guys ... I'm slowly drifting away ... and I only want simple contact forms ! 

    Regards Mark

    The widget you requested hasn't been implemented yet. As you may already know, there isn't a specific time-frame for a feature request implementation.


    I will send a reminder to our second level, hopefully we will get some updates on this request.

    I know it hasn't.

    Oh I know all about the timeframes ... it runs into years.

    It's not a reminder ... they've totally disregarded it.

    If you would though ...
