    People leaving false electronic signatures

    Asked by Purchasing Dept  on August 24, 2015 at 05:43 PM

    On our form we require buyers to place an electronic signatures. In some cases, we get some idiot people that think they can play little games by places a dot on the signature to bypass this requirement. Is there any way to ensure a valid signature is placed. Some of these people will place a dot to have the system think they left some sort of signature. Even though we have a disclaimer under the signature that tells these people that we wont respond to inquires with a falsifed signature we still get these type of people.

    Unfortunately, signatures are hard to verify, this is because it's solely up to the person on how to sign it. And we don't have a way to validate or verify it, unlike an email.

    We do have a new e-signature widget that you can use, check Adobe DC eSign services. Currently, what you can do is flag those submissions in your end and do not honor their submitted data. You can also verify their email address and contact them directly about an incomplete signature. You can use XVerify Email widget or the Email Validator widget, this will make sure that the email used is valid.

    I hope that helps.

    is there something perhaps that counts the number of pixels to validate an address. the people who place dots in the signature field know they have to place a signature in that field and are deliberately being jerks circumventing policies. Logic would dictate the more you move your cursor across the screen the pixel count increases, so if a valid signature is say 300 pixel positions, anything less than 300 would be someone not placing a valid signature.
    But thanks again with JotForms, we were using MachForm, but switched over to you guys. More features and alot more efficient .

    Thank you for your kind words. :)

    I understand what you mean with signatures, but unfortunately even that would not prevent a person from just drawing a line from one side to the other, or drawing a circle. Any error that would show them that their signature is too short would likely just make them try with a longer line.

    People tend to be inventive - if they are deliberately trying to fool the signature field, there is no way for us to programmatically prevent them from doing so on a simple signature-drawing field. Really the best way to work around these kinds of submissions is to use one of the methods our colleague has suggested above:

    1. You can use the Email Validator widget to make sure that they really have access to the email address that they have entered. This way, you can always contact them back to that address and inform them that their signature was invalid.

    2. You can use Adobe Document Cloud eSign service, which requires a far greater level of a person's authentication in order to have their submission digitally signed.

    I hope this helps.

    actually your right. they would try to draw a line instead of a few dots. but then again, any mark on a document is legally binding. you just have to match the IP address to them, but then again they can deny it was them. the only policy we have now is anyone that falsies the dispute the way they do, will not get any response,
    People who attempt to falsify or circumvent systems are basically telling companies what type of person they are, so therefore, we might decide to no longer accept future business from them, knowing they would pose a risk to companies. We required signatures on forms as a result of selected people and their conduct.
    Just thought there would be a way, but your right, they'd draw a straight line, but again a person's "Mark" on a document posses an interesting question to see if the form is legal or not. Some companies state that a signed document electronically is legal, where we still believe it has to be a face to face thing or "real ink".
    Was looking into what you suggested in Adobe, its called Adobe DC, that product is more of you sent a document to someone, they sign it and it comes back.
    But anyhows, guys thank you again for getting back to us. You definately have a great system.

    I was wondering, is there some kind of disclaimer I can put on my form for the e-signature? I want to make sure that when people sign it (whether they are doodling or legitimately signing) that they are agreeing to everything listed on the form. Just didn't know if you guys had a template made up of an e signature disclaimer I could use so people don't try and get out of something.
