HANDWRITTEN SIGNATURE PERSONAL AUTHENTICATION SYSTEM WITH TIME SERIES DATA OF CONTACT FORCE

摘要

PROBLEM TO BE SOLVED: To provide a handwritten signature personal authentication system for performing personal authentication which identifies a person by collating time series data of contact force when a person performs handwriting signature by holding a dedicated touch pen with the previously registered time series data of the contact force of the person to be authenticated.

SOLUTION: The handwritten signature personal authentication system is composed of a handwriting data input device for inputting handwritten signature data by acquiring force vector data caused by a handwriting pen operation, a data extracting device for extracting the time series data of the contact force of the handwritten signature from the handwritten signature data inputted by the handwritten data input device, and a determining device for collating the time series data of the contact force of the handwritten signature with the previously registered time series data of the contact force of personal handwritten signature data for determination, wherein the determining device calculates degree of similarity between the time series data of the contact force of the handwritten signature and the time series data of the contact force of the personal handwritten signature data, and performs personal authentication.
