PURPOSE: A computer security device using a hand action image, a computer security method using a hand action image, and a recording medium thereof are provided to determine whether to unlock by recognizing a user image photographed by a camera module, thereby enhancing security. CONSTITUTION: A camera module(10) is connected to a computer to photograph a user image. An image recognizing unit(20) applies a skin color detecting algorithm based on a user image signal corresponding to the user image to recognize the user image. An image analyzing unit(30) calculates an image matching rate by comparing the user image with a target image stored in a memory. An image control unit(40) controls locking or unlocking of the computer based on the image matching rate. The user image is an image based on hand actions of a user. |
