An electronic signature is in many processes legally sufficient to prove an identity. According to the U.S. Federal ESIGN Act passed in 2000, an electronic signature is an:

Electronic sound, symbol, or process, attached to or logically associated with a contract or other record and executed or adopted by a person with the intent to sign the record.

This ASP.NET MVC sample shows how to build a JavaScript signature pad to electronically sign documents.

ASP.NET: Adding electronic signatures to documents

The template contains a TextFrame with a specific Name that specifies that the content of this frame should be replaced with a signature. The signature stamp itself consists of an image placeholder and a merge field that gets merged using the MailMerge class. The signature stamp is stored in a sub-template and can be edited separately from the main template.

The JavaScript signature pad uses an HTML5 canvas element to draw the signature. The created signature image will be passed to the Controller method SignDocument and merged into the image placeholder.
