A security method and system using a touch screen that allows manipulation input using only an input tool which is not part of a user's body, i.e., finger manipulation, when a secure function such as secure printing is set instead of a normal function when the touch screen is manipulated, so as to prevent leakage of secure information due to fingerprint marks and smudges caused by finger manipulation. The security method includes checking whether or not a password is input, and inputting to the touch screen a password using an input tool which is not part of a user body.
