supports Digital Signatures. Authenticated users can digitally sign a section, lock it down and prevent tampering with the data. Versions, previous to 5.1, allowed the form designer to put a section in a form that could be signed using a text rendering of the user's name (user credentials) or a previously uploaded signature image. The user must be be authenticated to the Server.  Wet signature capture is now available in Version 5.1. A wet signature is a signature that is entered or created at the time of form entry.  Wet Signatures make it possible for the user to enter the signature using either a track pad/mouse, stylus or a touch screen in use mode. This feature becomes very important when designing for Mobile devices. Refer to the PageBreak control for more information on mobile forms.

Both authenticated and non-authenticated users may sign a form using a wet signature. If authentication is required, Signed Sections should be used.

When designing a form with an electronic wet signature control, the captured signature is attached to the form submission as a PNG image attachment. Any Live Forms document actions affecting the form data includes the signature png image. For example, should you choose to post the data to your web application, then the signature png is part of that posted data. Should you choose to email the data, the signature png will be attached to the email. Finally, should you choose none of these things, then the captured signature png is available for downloading by browsing your submissions within . See View and Edit Submissions Submissions Stored Inside of Live Forms for the details.

When the form is re-initialized from the submission documents, you must also supply the signatures. The initialization process will verify that the data has not changed (i.e., has not been tampered with) and the signature is still valid. If the signature is not valid, it is removed and the entire Section is displayed with a visible error (large red background). If it is valid, there is a green background and the Section cannot be edited.

 

 

Wet Signature

You can choose the signature format for a signed section in your form. Select any section control on your form and click the Security tab in the properties panel. The bottom portion of the tab is relevant to signatures. Refer to Security Properties for information on the Role dropdown. The drop down select has three options:

Here is an example of a standard signed section on a form when the signature property is set to Wet Signature. If the section is signed, the user can modify it by selecting the Edit this section button. The button will toggle to Sign this section and the wet signature and date in the lightbox will clear.
