Exactly what is a digital signature?
Use a digital signature for most of the same reasons which you
may sign a paper document. An electronic signature can be used to
authenticate digital information for example form templates, e
mail messages, and documents by utilizing computer
cryptography. Digital signatures assistance to establish the next
assurances:
Authenticity Digital signature helps you to ensure that the signer
is who she or he states be.
Integrity Digital signature helps you to ensure that the
information is not altered or tampered with because it was
digitally signed.
Nonrepudiation Digital signature helps prove the foundation from
the signed happy to both sides. "Repudiation" refers back to the act
of the signer denying any connection to the signed content.
To create these assurances in regards to a form template, you have
to digitally sign your form template. You may also enable digital
signatures for the form template so your users could make exactly
the same assurances concerning the forms they complete. Either in
situation, the next needs should be met to be able to digitally sign
an application or form template:
Digital signature applies.
The certificate connected using the digital signature is current
(hasn't expired).
The signing person or organization, referred to as writer, is
reliable.
The certificate connected using the digital signature is
disseminated towards the writer with a reliable certificate
authority (CA).
Compatibility factors
Whenever you produce a form template, you are able to enable
digital signatures to ensure that users can also add them with the
idea to the whole form in order to specific areas of the shape. In
Microsoft 'office' InfoPath 2007, you may also decide to design a
browsercompatible form template. A browsercompatible form
template is really a form template that's developed in InfoPath
using a specific compatibility mode. A browsercompatible form
template could be browserenabled when it's printed to some
server running InfoPath Forms Services. In browserenabled form
templates you are able to only enable digital signatures to be
included to specific areas of the forms that users complete.
Whenever you enable digital signatures for areas of the shape, the
signatures apply simply to the information in individuals specific
areas of the shape.

Using digital signatures in InfoPath
When making an application template, you are able to specify
whether users can also add digital signatures once they complete
an application according to your form template. You may also
specify whether users can sign the entire form or simply area of the
form. Should you enable digital signatures to enable them to be
included to area of the form, you have to pick which data within
the form could be signed. You are able to furthermore affiliate that
data having a section that you simply increase the form template.
Once signed, the shape or area of the form which was signed can't
be altered without invalidating the signature.
When making an application template, you may also specify
whether users are permitted to include multiple digital signatures
to some form, and whether individuals signatures ought to be co
signed (by which situation each signature is in addition to the
other signatures) or countersigned (by which situation each
signature signs the shape, along with the signatures that precede
it).
Note: If your form template was created according to an XML
Schema, you are able to enable digital signatures for your form
template only when the XML Schema includes a node that's in the
internet Consortium (W3C) XML digital signature namespace
Additionally to enabling digital signatures to ensure that users can
sign forms that derive from your form template, you may also
digitally sign the shape templates that you simply design. Digitally
signing an application template authenticates you because the
designer from the form template in the same manner that the
digital signature on the form authenticates the consumer who
completed the shape. Adding an electronic signature to some form
template also enables the shape template to function in the Full
Trust level. For instance, an application template which contains
managed code that utilizes the entire Trust degree of security must
be either placed on a user's computer or digitally signed through
the form template designer to ensure that its used.
