Nuance omniform filler 5.5 for designing and distributing forms User Manual

Digital signature fields are only of value if you can verify that the signatures are valid. 
After a digital signature field is signed, the authentication process tries to verify the 
signature to ensure that it is valid.

▼

Open the form in OmniForm Filler.

2. Choose Field Security in the View menu if it is not already turned on.

Icons appear next to signed fields indicating whether signatures have been 
verified or not. A pen with a check mark indicates that the signature was 
verified to be valid. A pen with a question mark indicates the signature cannot 
be verified.

If a signature field cannot be verified, it could be for one of these reasons:

◆

The form’s data has changed since the form was first signed.

◆

The form’s design has changed since the form was first signed.

◆

The signer of the form could not be identified, possibly because the 
OmniForm user database or authentication service is not accessible, or 
because the authentication service could not verify the signer.

◆

The signer of the form could not be identified, possibly because the user 
password was changed since the form was first signed. (This reason is only 
applicable to OmniForm signature fields.)

You can also choose Security... in the Tools menu to get the verification 
status for signed signature fields.

Fields that are locked by the 
signature are highlighted 
with a blue border.

A pen with a check mark indicates that the signature 
was verified to be valid. (A pen with a question 
mark indicates that the signature cannot be verified.)
