[ The eye movement identifying unit 120 may be a camera using an eye tracking technique. The eye movement identifying unit 120 can identify eye movements of the user using the eye tracking technique. Eye tracking technology captures user eye movements to determine eye position, and can be used in various fields such as design, image, and control as well as games. Since the eye tracking technology is a known technology, a detailed description will be omitted. According to the present embodiment, the eye movement identifying unit 120 can identify the eye movement of the user gazing at the object displayed on the display unit 110, and calculate the position information of the eye in which the motion is identified. The eye movement identifying unit 120 can identify the eye movement of the user when the object displayed on the display unit 110 is gazed for a predetermined time or when blinking occurs. That is, the eye movement identifying unit 120 can calculate the position information of the eye in which the motion is identified when the eye movement of the user occurs.

The password generating unit 130 generates a password by combining the objects input according to the eye movement of the user identified by the eye movement identifying unit 120. The password generating unit 130 can generate a password based on the input order of objects input by the eyeball motion identifying unit 120. [ Also, the password generating unit 130 can generate the password using the moving pattern of the eyeball movement to be identified. For example, the password generating unit 130 generates position information of the eyeball according to the eye movement of the identified user gazing at an object displayed on the display unit 110 in the eye movement identifying unit 120, It is possible to generate a password based on the object corresponding to the above-described position information.

The password authenticating unit 140 compares the password generated by the password generating unit 130 with a preset password to perform password authentication. On the other hand, password information for unlocking the device and / or the program may be preset and stored in the storage unit (not shown). At this time, the preset password information is set by the user, and may be input directly by an input device such as a keyboard, a touch panel, or the like, or may be inputted by identifying the eye movement of the user who is looking at the object.

Referring to FIG. 3, the secure password input device using the eye movement recognition according to the present embodiment further includes a face recognition unit 210 and a spy detection unit 220.

The face recognition unit 210 recognizes the face of the user who inputs the password. That is, the face recognition unit 210 looks at the object displayed on the display unit 110 and recognizes the face of the user who inputs the password. When the secure password input device using the eye movement recognition according to the present embodiment further includes the face recognizing unit 210, the lock releasing unit 150 compares the faces after the password authentication is performed, The set device and / or program can be released. That is, after the password authentication is performed by the password authenticating unit 140, the unlocking unit 150 deletes the face of the user who entered the generated password and the user who inputs the password for releasing the locked device and / And if they match, it is possible to release the lock. At this time, the face of the user who inputs the generated password can be photographed by the camera and stored in advance in a manner matching with the password corresponding to the storage (not shown). As described above, the face of the user who inputs the generated password is compared with the face of the user who inputs the password for releasing the locked device and / or the program without immediately releasing the lock after the password is authenticated, The security in releasing the locked device and / or the program can be further improved. That is, if a password is leaked, even if an attempt is made to unlock a device and / or a program locked by another person using the leaked password, since the lock does not coincide with the face of the user set at the time of registering the initial password, Can be further improved.

The snooze detection unit 220 detects a user other than the user gazing at the object to generate a password. For example, the snooze sensing unit 220 may be a camera for sensing a user other than a user staring at an object to generate a password. More specifically, the snooze detection unit 220 detects the number of eyeballs, thereby checking whether there is a user other than the user gazing at the object. Generally, the user who inputs the password has two eyes. Accordingly, the snooze detection unit 220 displays the object through the display unit 110 only when there are two eye movements of the user gazing at the object to generate the password. However, when the at least three eyes of the user gazing at the object are detected to generate the password, the snooze detection unit 220 determines that there is a third person who spies on the password input, Can be removed on the screen of FIG. Thus, it is possible to prevent spying of the inputted password and to prevent the password from being leaked in advance.
