“…The single encrypted intra-frame prediction pattern approach also lacks adequate protection for P and B frames in videos. Rohit [5] used two one-dimensional logistic maps cross-coupled with each other as a pseudo-random series generator and encrypted the motion vector according to the congruence rule, which thoroughly corrupted the contour information of the video object. The cross-coupling enhances the complexity of chaotic sequences, but only the double mapping iterates over each other, making it weak against differential attacks.…”

<p>The traditional video encryption algorithm only encrypts video images, which has the problems of an extended time-consuming algorithm and poor format retention. To improve the efficiency of video encryption, this paper proposes a multi-link selective video encryption algorithm based on the Cross Coupled Map Lattices system by combining H.264/AVC video coding structure. The algorithm reduces the amount of encrypted data while ensuring encryption security to satisfy the needs of video encryption security and real-time performance. The encryption algorithm’s security and visual encryption effect are analyzed subjectively and objectively. The experimental results show that the encryption scheme has an excellent visual encryption effect and strong attack resistance, the encryption time consumption is low, and the video format remains unchanged. It can be applied to real-time video encryption occasions such as video conferences.</p> <p> </p>

“…With encryption in place, even if unauthorized individuals gain access to the stored or transmitted video data, they would not be able to understand or make use of it without the encryption key. The algorithms used to encrypt surveillance videos can be categorized into two types: (1) Selective Encryption and (2) Full Encryption [4,5]. In Selective encryption region of a video called ROI (Region of Interest) can be encrypted in a video to preserve privacy.…”

The widespread use of surveillance cameras has initiated privacy concerns among individuals being captured by these devices. Due to the limited internal storage capacity, these cameras often transmit recorded videos over unreliable networks. This situation creates opportunities for attackers to exploit vulnerabilities, such as launching Man-in-the-Middle attacks, replayed scene attacks, and tampering with the video content. Considering these risks, this paper introduces a new chaotic map-based encryption scheme for surveillance videos. The work proposes a novel chaotic map using cascading and coupling operations on functions and is referred to as a Cascaded Coupled Logistic-Sine-Cosine (CCLSC) map. The chaotic performance of the novel CCLSC map has been evaluated using the Lyapunov exponent and the Bifurcation diagram. The scheme to encrypt surveillance videos is designed using the novel CCLSC map and our earlier designed Sine-Tangent-Sine (STS) chaotic map. The process involves extracting individual frames from the video and subsequently encrypts each frame as a digital image. The encryption of each frame involves three steps. The first step generates a Dynamic Chaotic Matrix (DCM) using CCLSC and STS map. The second phase is pixel scrambling using DCM and the final step changes the pixel values using DCM. Our results validate the security, robustness, and effectiveness of the proposed method.

“…In regular mode, the probability is selected from the content based on previously encoded syntax elements whereas, in bypass mode, the fixed probability is used. The selective encryption is performed by using the bypass mode (Malladar and Kunte, 2021), ensuring format compliance and maintaining the bit rate of HEVC-encoded videos.…”

Cloud computing has become a significant technology with rapid popularization offering many services with highly effective computation and large-scale storage solutions. As multimedia files are growing explosively, securely storing them for authorized access is a major task. Concentrating on video file storage in a public cloud environment, the security and privacy of those outsourced videos are the major concerns. A selective frame encryption approach is proposed to encrypt the semantic elements of the selected frames of High Efficiency Video Coding (HEVC) compressed videos by storing them in the cloud. The semantic elements of HEVC videos are extracted and encrypted by a modified Advanced Encryption Standard (AES) operation in CFB mode with a Substitution-Box (S-Box). A dynamic, nonlinear 2D discrete hyperchaotic mapping-based S-box generation method is proposed to enhance security by providing good confusion, diffusion, and scrambling. The performance analysis of generated S-box and experimental results show that the proposed selective encryption highly resists attacks and encrypts with reduced time complexity.
