Method and apparatus for providing combined authentication service

An apparatus for providing a combined authentication service, comprising:

• a combined authentication information setting unit for setting combined authentication information by acquiring an entry window location and authentication characters from a user;
• a user interface unit for displaying an entry window including an entry keypad at the entry window location and acquiring entry information including entry characters and entry coordinates from the user via the entry window;
• and
• a combined authentication performance unit for performing combined authentication by verifying the entry characters and the entry coordinates.

An apparatus for providing a combined authentication service, comprising:

• a combined authentication information setting unit for acquiring a coordinate mapping layer region as a region separate from a character entry region including a character entry keypad when a user makes a region setting entry, acquiring reference characters and reference coordinates via the character entry region when the user makes a character setting entry, and calculating reference mapping coordinates by mapping the reference coordinates to the coordinate mapping layer region, thus setting combined authentication information;
• an authentication target information acquisition unit for acquiring authentication target characters and authentication target coordinates via the character entry region when the user makes an authentication entry;
• and
• a combined authentication performance unit for calculating authentication target mapping coordinates by mapping the authentication target coordinates to the coordinate mapping layer region, and for verifying the authentication target characters and the authentication target mapping coordinates, thus performing combined authentication.
