    Patent number: 8612763
    Abstract: Methods, processes, systems and devices for allowing a computer user to sign and execute a document over the interne using a pointer device such as a mouse to generate a digital signature by an cursive signature (handwritten). The invention allows for vector points in the digital signature to be encoded/encrypted, stored and later be retrieved so that it can be verified where it came from, and what specific document it was on. If necessary, the invention allows for a newly executed signature to be forensically verified against a signature sample.
