Improved user interface design for the online signature verification

摘要

PURPOSE: An improved user interface design for verifying an on-line signature is provided to verify the person himself by registering the own signature using an electric pen. CONSTITUTION: The improved user interface design is able to use a secrete number at need and registers a signature in a signature verification database by inputting the same signature four times and pressing the "OK" button. In case of occurring an error on writing a signature, the user can write again his signature by pressing the "NEW" button. After writing a signature and pressing the "OK" button, the interface compares the writing signature to the signature of the already registered signature database and determines whether the written signature is the registered signature or not. The interface improves the security by preventing the signature from leaking out to other person by making the figures of the signature invisible while the user signs on the user interface.
