VIDEO SURVEILLANCE SYSTEM APPLIED WITH REAL-TIME CCTV VIDEO ENCRYPTION METHOD

摘要

Disclosed is a video surveillance system to which a real-time CCTV video encryption method is applied. The video surveillance system to which the real-time CCTV video encryption method is applied includes a camera and an encryption device for receiving an image from the camera. The encryption device includes a receiving module; a block size determination module; a block definition module; a block encryption module; and a block exchange module. The block definition module circular-shifts a first encryption key value to generate a second encryption key value, and defines a third block and a fourth block in a first frame among a plurality of frames included in the image according to a determined block size, the second encryption key value, and a random function.;COPYRIGHT KIPO 2019
