Abstract
This present invention includes a method for capturing and transmitting data captured from a writing instrument in a secure manner. More specifically, the biometric information collected from the pen is coupled with at least one additional data point for encryption. The user initially uses the pen to create a signature which is converted into an encrypted reference value in accordance with the present invention. When authentication is desired, the user uses the same or similar pen to create a signature which again is converted into an encrypted data value. Thereafter, the encrypted reference value is compared to the encrypted data value to determine if the values substantially match. There is not need to retain the original reference signature, thereby enhancing the security of the overall system.
