Electronic Signature Field

As made apparent by its very name, Electronic Signature Field is a software utility that serves a very particular purpose, namely that of offering you various ways of applying a digital signature to SharePoint items as well as document properties and content. This sort of product could really come in handy in the enterprise environment, where documents containing sensitive data are handled.

Regarding the signature providers the tool can handle, you should know that Windows Integrated Authentication is on the list, but you can also turn to a hand-written signature, also known as Topaz, as well as to Active Directory, which implies that you come up with a username and a password.

The signature created using this SharePoint component encapsulates details on your identity along with when the signing took place, a hash sum, and optionally, the item version. All this data is encrypted, and once the item is signed, a new icon pops out to attest its validity. In case subsequent editing is carried out without the field being signed again, the aforementioned icon disappears, thus reflecting the fact that alterations have occurred.

You may also want to take into account the fact that the verification of the signature is done in real time, and in case it is deemed invalid, a visual notification is pushed.
