Co-Design Secure Control Based on Image Attack Detection and Data Compensation for Networked Visual Control Systems

The incomplete and untrue data caused by cyber attacks (e.g., image information leakage tampering) will affect control performance even lead to system instability. To address this problem, a novel co-design secure method based on attack detection compensation for networked visual systems (NVCSs) is proposed. Firstly, the existing problems of NVCSs under are analysed, including encryption, watermarking-based online presented. Then, detector double-layer mechanism timeout digital watermarking designed real-time, integrity authenticity discrimination images. Furthermore, according results, an scheme cubic spline interpolation post-prediction update proposed reduce effect cumulative errors improve performance. Finally, optimized considering characters inverted pendulum systems, experimental results demonstrate feasibility effectiveness method.
