“…(b) Embedding in the stage of transform and quantification It is proposed information embedding algorithm that embed information to nonzero QTCs by a simple arithmetic operations [9,[13][14][15]. This method has the lack which is sensitive to the QP (quantization parameter) and don't consider the robustness.…”

“…Video watermarking algorithm is closely related to video encoder structure. HEVC is built on H.264/AVC platform, therefore in general, it has been performed the research works for applying watermarking algorithms used in H.264/AVC to HEVC watermarking [7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”

“…Among various watermarking algorithms, the algorithm that embed watermark to nonzero QTCs is highest in information embedding capacity and is robust for different attack [13][14][15][16][17][18][19]. In embedding watermark in QTCs, challenges are the error drift and the computational complexity.…”

With rapid development and application in the new video compression standard HEVC, it is necessary new digital watermarking technology capable of application for HEVC. In this paper, we propose a new watermarking method by modifying QTCs (Quantized Transform Coefficients) for HEVC. In proposed method, the watermark is embedded by modifying non-zero QTCs (Quantized Transform Coefficients) of the 4×4 luma transform block of intra predicted I-frame. In order to resist error drift phenomena, we differently modify the significant bits of 4×4 luma block with its direction of intra prediction modes. In decoder, the embedding watermark bits can extract without the need of any extra information. The experimental results show that proposed method is low in computational complexity and is efficiently resist error drift.

“…Besides, video features and random keys are utilized to improve the security and robustness of the watermarking. Mohamed et al [22] integrated two robust watermarking algorithms in HEVC codec, which includes XY method and LSB method for watermark embedding. These two watermarking methods are implemented by altering the value of quantized and transformed coefficients in HEVC coding.…”

With the rapid development of Internet of Things and multimedia technologies, people are paying more attention to the security of images and videos. To further improve the security of video content, a video watermarking algorithm based on the high efficiency video coding (HEVC) compression domain is proposed in this paper. The scheme embeds watermark information in the quantized coefficients, which can solve the cumulative error caused by watermark embedding. Moreover, the all phase biorthogonal transform (APBT), an improved transform, is used to compress the watermark data at the digital watermark preprocessing stage, optimize the watermark embedding scheme, and improve the embedding capacity of video watermarking. Due to the characteristics of HEVC video coding, most HEVC video watermarking schemes based on compression domain cannot resist recompression attack. To solve this problem, on the basis of APBT and singular value decomposition, an anti-HEVC recompression video watermarking algorithm is proposed and can effectively resist the HEVC recompression. Experimental results show that even when the quantization parameter is larger than 40, the extracted watermark still has good image quality. In addition, the algorithm also has a good performance in noise resistance. KEYWORDSAll phase biorthogonal transform (APBT); High efficiency video coding (HEVC); Recompression; Video watermarking At present, compared with H.264-based video watermarking technology, there are a few studies on watermarking technology for HEVC videos. To achieve video copyright protection and content authentication [6], the watermark information can be embedded in spatial domain or compression domain. Qiu et al.
