Abstract: An operation method of an electronic device is provided. The operation method includes registering, as reference signature data, at least one handwritten signature inputted into the electronic device by a user input means, authenticating an inputted handwritten signature by comparing data of the inputted handwritten signature with the registered reference signature data when the handwritten signature is inputted by the user input means, and further registering, as reference signature data, handwritten signature data regarding the inputted handwritten signature when the inputted handwritten signature is authenticated normally as a result of the authentication.
