Abstract
A writing instrument that is configured with sensors to measure biometric data including the friction forces, accelerations, and angles applied by the writing instrument to a writing surface during a writing event such as a signature. The mean energy dissipated by a valid signature owner during a signature event, is significantly lower than that of a forger or other falsifier. By recording and storing the mean minimal energy for registered, authorized signature owners, a signature energy database can be compiled. Registered authorized signature owners are positively identified by writing their signature with the biometric writing instrument that communicates the energy information to the energy database for verification. The energy database may be located at a remote location to provide signature verification when the signature requester and signature provider are not co-located.

9. A method for verifying signatures, comprising:
-
collecting data from sensors on a writing instrument during a writing instrument event;
specifying a claimed identity of the writing instrument user;
computing the mean energy dissipated during the writing instrument event; and
,comparing the mean energy dissipated during the writing instrument event, to historic mean energy data for the claimed identity. - View Dependent Claims (10, 11, 12, 13)
