METHOD AND DEVICE FOR ELECTRONICALLY CAPTURING A HANDWRITTEN SIGNATURE AND SAFEGUARDING BIOMETRIC DATA
First Claim
1. A method comprising:
- (i) providing a computer apparatus having a first monitor configured to display an electronic document to be signed by a signer,(ii) providing a signature capture apparatus having a second monitor, the signature capture apparatus being an individual unit separate from, but in communication with, the computer apparatus and being configured to electronically capture a handwritten signature of the signer and biometric data of the signer'"'"'s signature,(iii) generating in the computer apparatus a first hash sum of the electronic document to be signed by the signer,(iv) transmitting to the signature capture apparatus one of;
(a) the generated first hash sum and (b) the generated first hash sum and the electronic document to be signed,(v) displaying on the first monitor of the computer apparatus the electronic document to be signed by the signer and the first hash sum of the electronic document,(vi) displaying on the second monitor of the signature capture apparatus the first hash sum transmitted from the computer apparatus,(vii) electronically capturing the handwritten signature of the signer made on the signature capture apparatus, thereby generating signature data,(viii) encrypting in the signature capture apparatus one of;
(a) the signature data and (b) the signature data and the first hash sum,(ix) transmitting to the computer apparatus one of;
(a) the encrypted signature data and (b) the encrypted signature data and the encrypted first hash sum, and(x) storing on a computer-readable medium one of;
(a) the encrypted signature data, (b) the encrypted signature data and the encrypted first hash sum and (c) the encrypted signature data, the encrypted first hash sum and the signed electronic document.

Abstract
A method and apparatus for encrypting an electronic document involves a computer having a first monitor and a signature capture apparatus configured to capture a handwritten signature on a second monitor. A hash sum of the electronic document generated in the computer is transmitted to the signature capture apparatus. The electronic document and the first hash sum thereof are displayed on the first monitor. The first hash sum is also displayed on the second monitor. After electronically capturing the handwritten signature, the signature data and the first hash sum are encrypted in the signature capture apparatus and then transmitted to the computer. The encrypted signature data, the first hash sum and the signed document are stored on a computer-readable medium.
