Method, mobile terminal and system for providing different authentication values according to contact method of mobile terminal

摘要

System and method of authenticating a terminal. An authentication system which provides an authentication value specified by a tilt angle of a terminal, includes a terminal which measures the tilt angle, and a short-range communication reader which receives the tilt angle and terminal identification data from the terminal by using short-range communication and which generates the authentication value based on the tilt angle. The short-range communication reader authenticates the terminal based on the authentication value.

1. An authentication system of authenticating a terminal, the system comprising:
a short-range communication reader; and a terminal which measures a tilt angle as the terminal approaches a short-range communication reader; and wherein the short-range communication reader receives the measured tilt angle and terminal identification data from the terminal by using short-range communication and generates an authentication value based on the tilt angle, wherein the short-range communication reader authenticates the terminal based on the generated authentication value, wherein the terminal measures the tilt angle of the terminal and registers the measured tilt angle for use as the authentication value when a communication link with the short-range communication reader is established, wherein the short-range communication reader generates the authentication value based on the tilt angle, separately receives from a user or the terminal additional authentication data, and authenticates the terminal based on the generated authentication value and the additional authentication data, and wherein the authentication value is generated by combining at least two tilt angles that are obtained consecutively at predetermined time intervals when the terminal approaches the short-range communication reader.
