TLDR
In this paper, a cellular automata (CA)-based ROI (region of interest) image encryption system was proposed, which can effectively reduce computational cost and maintain an appropriate level of security.Abstract:
In this paper, we design a cellular automata (CA)-based ROI (region of interest) image encryption system that can effectively reduce computational cost and maintain an appropriate level of security. The proposed image encryption system obtains a cryptographic image through three steps. First, a region of interest with high importance is extracted from the entire image using deep learning. We use the YOLO (You Only Look Once) algorithm to extract the ROI from a given original image. Next, the detected ROI is encrypted using the Chen system, a chaotic-based function with high security. Finally, the execution time is effectively reduced by encrypting the entire image using a hardware-friendly CA. The safety of the proposed encryption system is verified through various statistical experiment results and analyses.read more

SecureCam: Selective Detection and Encryption Enabled Application for Dynamic Camera Surveillance Videos
TL;DR: Wang et al. as discussed by the authors proposed an effective security application SecureCam based on selective detection (focused moving objects) and protection using encryption, which implements a novel low computational unsupervised learning algorithm, i.e., Motion-Fusion (MF) for more precise motion detection in the mobile camera videos.

You Only Look Once: Unified, Real-Time Object Detection
TL;DR: Compared to state-of-the-art detection systems, YOLO makes more localization errors but is less likely to predict false positives on background, and outperforms other detection methods, including DPM and R-CNN, when generalizing from natural images to other domains like artwork.
