Abstract

Abstract: In order to improve the security of monitoring system and the speed of full image encrypting, based on the fast image-block encryption method, the concept of Region of interest encryption for infrared image is advanced in this paper. The OSTU algorithm are used to extract the ROI for encryption, then a Lorenz sequence is processed in order to ensure the randomness. Based on the random Lorenz data sequence, the ROI encryption is processed. Compared to the other encryption methods, the Lorenz ROI encryption has better performance on operation speed, security and encryption effect.

Key words: region of interest, infrared image, encryption, chaos system
