Abstract:
1. A method of storing a digital graphic signature comprising the steps of: (a) creating the digital graphic signature by a person forming a personal, handwritten stylized script signature of the person with a computer pointing device, the signature being of a type like that used by the same person to manually sign documents with a pen, wherein the process of forming the stylized script signature includes timeable movements similar to those present when manually signing a document with a pen; (b) creating a vector map of the signature by generating signature data comprising a series of vector points having vector point positions useful for analyzing authenticity of the signature, each position acquired at a determinable time in a time period during which the signature is formed; and (c) storing the vector points and time information with which a time associated with each position is determinable, wherein a combination of the vector points and time information enable provision of a replica of the handwritten stylized script signature and a replica of forming the handwritten stylized script signature, (d) generating both a replica of the handwritten stylized script signature and a dynamic re-creation of forming the handwritten stylized script signature, wherein the stored vector points and dynamic re-creation of forming the handwritten stylized script signature enable forensic analysis to authenticate the signature by matching the dynamic re-creation of forming the handwritten stylized script signature with another signature, (e) generating and appending a graphic watermark to a displayed image of the digital graphic signature, and (f) creating an identification code from the digital graphic signature, wherein the digital graphic signature is linked to a document signed with the handwritten signature.
