Abstract
Provided is a segment-based handwritten signature authentication system and method and, more specifically, to a segment-based handwritten signature authentication system and method, in which handwritten signature authentication based on segments is performed by using handwritten signature characteristics information based on segments disjointed by a user's signing behavior.
Claims19
A segment-based handwritten signature authentication system, the system comprising:
- a handwritten signature input unit that includes a touch input unit that outputs touch data, as handwritten signature input data, including position data and pressure data with respect to positions that are touched by a signer for a handwritten signature;
- an enrollment unit that enrolls handwritten signature characteristics information of each signer;
- and
- a handwritten signature authentication unit that identifies and counts handwritten signature segments disjointed by the signer from the handwritten signature input data entered from the handwritten signature input unit,
- collects handwritten signature characteristics information (Σ) including characteristics information of the entire handwritten signature and the handwritten signature segments with the counted number of the handwritten signature segments,
- maps the collected handwritten signature characteristics information to identification information of the signer,
- enrolls the collected handwritten signature characteristics information in the enrollment unit,
- collects handwritten signature characteristics information (Σ) including behavioral characteristics information of the handwritten signature and the handwritten signature segments from the touch data entered through the touch input unit of the handwritten signature input unit upon request for handwritten signature authentication,
- loads the enrolled handwritten signature characteristics information (Σ′) that corresponds with the identification information of the signer who requests the handwritten signature authentication, and
- performs a segment-based handwritten signature authentication according to a match rate by comparing the enrolled handwritten signature characteristics information (Σ′) with the collected handwritten signature characteristics information (Σ).

A segment-based handwritten signature authentication method, the method comprising:
- an enrollment process in which a handwritten signature authentication unit identifies and counts segments disjointed by a signer from handwritten signature input data entered through a handwritten signature input unit, collects handwritten signature characteristics information (Σ) including characteristics information of entire handwritten signature and handwritten signature segments with the counted number of the segments, maps the handwritten signature characteristics information to identification information of the signer, and enrolls the handwritten signature characteristics information in the enrollment unit;
- and
- a handwritten signature authentication process in which the handwritten signature authentication unit collects handwritten signature characteristics information (Σ) including characteristics information of entire handwritten signature and handwritten signature segments from touch data entered through a touch input unit of the handwritten signature input unit upon request for handwritten signature authentication, and performs handwritten signature authentication according to a match rate by loading the enrolled handwritten signature characteristics information (Σ′) that corresponds with the identification information of the signer who requests handwritten signature authentication and comparing the enrolled handwritten signature characteristics information (Σ′) with the collected handwritten signature characteristics information (Σ).
