Abstract
A mobile telephone is provided which includes a touch screen, character recognition means for recognizing data inputted via the touch screen, and a processing unit for receiving at least one secret symbol inputted via the touch screen while the mobile telephone is in a password registration mode. The processing unit providing the at least one secret symbol to the character recognition means for recognizing the at least one secret symbol and generating feature data corresponding thereto. The processing unit stores the feature data in a database to register the at least one secret symbol as a password. The processing unit further compares the stored feature data with feature data corresponding to data inputted via the touch screen for determining whether the inputted data is substantially similar to the at least one secret symbol while the telephone is in a password identification mode. A method is also provided for registering a secret symbol as a password. A method is further provided for identifying a secret symbol inputted via the touch screen as the correct password.
