Abstract

The present invention relates to a pattern authentication method for preventing smudge and shoulder surfing attacks, the method comprising a pattern registration step and a pattern authentication step, wherein the pattern registration step comprises the steps of: by an input unit of a pattern authentication device, receiving a pattern from a user; by a matching unit, matching a code value corresponding to the pattern being received from the user and storing the code value in a storage unit; and by a key derivation ID (KDI) generator, generating a user key derivation ID (KDI) by matching the code value with a quantum random number table comprising quantum random numbers generated by a quantum random-number generator.

Description

technical field [0001] The present invention relates to a pattern authentication method for preventing stains and peeps of mobile devices. In particular, it relates to a user pattern authentication method that combines an event of touching a specific area of ​​a mobile device and a user pattern input to prevent smudge and peeping attacks. Background technique [0002] With the popularization of the use of mobile devices, attention to techniques for preventing leakage of personal information has also increased. Although the commonly used authentication method utilizing user input pattern on mobile devices has the advantage of simplicity, it is easily attacked by the shoulder-peeping hacker type (over-the-shoulder peeping, surveillance video, CCTV video recording). Registered Patent No. 10-1700799 (Method of User Terminal with Shoulder Peeking Prevention Function) discloses a method of judging the user's gaze area and non-gazing area and recombining the corresponding characte...
