The method for appling the masking for the protection of privacy to the face area detected by using face recognition technology

The present invention relates to a method for providing masking for protecting privacy by extracting a face area from an image photographed by an image processing device using a face recognition technology. More particularly, the present invention can prevent privacy invasion in advance caused by spread without permission by storing a video recorded or extracted by an image processing device such as a black box and CCTV after converting filename extension of the video which is securable in regular players that cannot be played. Also, a face area included in the image can be tracked or recognized using a face recognition tracking tool based on face recognition technology. A skin layer corresponding to the recognized 2D face area is masking treated in 3D type, thereby enabling a user to play or download an image in which only face areas are masking treated without modification/damage. In addition, if a masking release in face or region is required for searching out corroborative data or criminal, a user can cancel the masking treatment of the image of which the skin layer of face or region was masking treated in 3D and can play and download the image.
