<p>PURPOSE: A password input system and a method thereof are provided to improve security, convenience, and an input speed by inputting a temporary password generated through a random keypad to random keypads without exposing a password. CONSTITUTION: A keypad output unit(110) randomly arranges and outputs random keypads according to a layout set in a keypad interface. A password storage unit(120) stores a password. When the random keypad of a user is inputted, a decoding unit(130) decodes a character key of the random keypad corresponding to a position of the inputted random keypad as an input password based on a character key arrangement state of one random keypad. A comparing unit(140) compares the input password with the preseted password. [Reference numerals] (110) Keypad output unit; (120) Password storage unit; (130) Decoding unit; (140) Comparing unit; (150) Display unit; (160) Random key changing unit</p> |
