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.

Abstract: The present disclosure relates to a handwritten signature authentication system and method. More particularly, the present disclosure provides a system and method of authenticating a handwritten signature based on dynamic movement tracking of spatial-division segments, in which handwritten signature authentication is performed by handwritten signature characteristics information (i.e.

Abstract: Provided is a segment-block-based handwritten signature authentication system and a method thereof, and more particularly, to a handwritten signature authentication system and a method thereof that enrolls a handwritten signature including handwritten signature characteristics information based on segment blocks disjointed by a user, acquires segment-block-based handwritten signature characteristics information from the handwritten signature upon request for handwritten signature authentication, and performs handwritten signature authentication by comparing the pre-enrolled handwritten signature characteristics information based on segments and the acquired handwritten signature characteristics information.

Abstract: The present disclosure relates to a handwritten signature authentication system and method and, more particularly, to a time-division handwritten signature authentication system and method, in which handwritten signature authentication is performed by handwritten signature characteristics information based on segment blocks including segments divided by a predetermined time slice.

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.

Abstract: Provided is a handwritten signature authentication system and method in which handwritten signature authentication is performed by conducting at least one of the following comparisons: a comparison between a pre-enrolled handwritten signature image and a tracked handwritten signature image traced during the signing process, a comparison between a pre-enrolled handwritten signature behavioral characteristics and a handwritten signature behavioral characteristics collected during the signing process, and a comparison between a pre-enrolled handwritten signature image and a reconstructed handwritten signature image regenerated by the handwritten signature behavioral characteristics collected during the signing process.

Abstract: Provided is a personal authentication system that performs an online personal authentication and, more particularly, to a personal identification and anti-theft system and method, which provide, to a user terminal unit, an authentication key (C) issued upon request for a personal authentication and generate an authentication association value corresponding to the authentication key (C) by a disposable random key in performing the personal authentication. Therefore, even if the authentication key (C) is lost or deprived, the present invention can prevent an appropriation of the key and achieve a safe personal authentication, thereby preventing illegal use of the personal authentication and the authentication key (C).

Abstract: Provided is a system and method for authenticating a user according to login and financial transactions, such as payment and transfer, and more particularly, to a system and method for authentication using a quick response (QR) code, in which a quick response (QR) code including authentication information is displayed on the computer terminal of a user, the QR code is scanned through a smart device such as a smartphone, and the authentication is performed using the scanned QR code by accessing a QR authentication server included in the QR code.

Abstract: Provided is a system for preventing personal information leakage and, more particularly, related to a legal authentication message confirmation system and method which enables a user to identify whether an authentication message transmitted to the user's mobile communication terminal during user authentication originates from a trusted source, thereby preventing damage caused by pharming, smishing, and the like, such as personal information leakage and small sum payment fraud.

Abstract: Protection for a file system is provided. The protection includes generating first digital signature keys and a system security manager's certificate for a system security manager. A system security manager's certificate is stored onto a security kernel when installing an operating system on a server computer. Second digital signature keys and a user's certificate are generated for a general user. An access authority of the file system is set. A user is identified through a digital signature authentication method when the user tries to access the file system. The user is given access authority for the file in accordance with an identification result.
