Many automobile drivers have come to believe that installation of video recording equipment in a car is essential to providing evidence in case of a car accident and to facilitate reporting to police. Thus, it is important to develop an in-vehicle video recorder with high resolution to document accidents. To provide such video quality, the H.264 video format, which offers high compression and good quality, has been used for an in-vehicle video recorder. However, due to problems with fabricated evidence of digital records, we propose a new watermark method to authenticate in-vehicle video. This watermarking scheme authenticates and protects in-vehicle video. The proposed scheme manipulates the quantization table of the I-frames in car surveillance videos and embeds watermarks in the I-frames. Experimental verification was done to confirm the authentication and tamper detection of the proposed watermark image method for in-vehicle video.

“…The sign parity of the coefficients and the values of the middle-frequency coefficients are altered for watermark embedding in the I frame. 25 In Dutta et al, 26 the watermark is embedded in the nonzero coefficients of the P frame in the compressed domain to achieve better perceptual quality of the watermarked video frames and a minimal increase in video bit rate. In Stütz et al, 27 a structure preserving non-blind H.264 watermarking scheme was suggested to insert watermarks through substituting secret bits in the motion vector differences of the non-reference images.…”

Digital watermarking is a promising and efficient methodology for protecting the copyright of the transmitted multimedia data. Three-dimensional videos (3DVs) are transmitted and stored in the form of compressed information.Thus, there is a great need for compressed 3DV watermarking. This paper presents 2 proposed hybrid watermarking schemes for securing the 3DV transmission. The first watermarking scheme is the homomorphic transform-based singular value decomposition in discrete wavelet transform domain. The second scheme is the 3-level discrete stationary wavelet transform in discrete cosine transform domain. The objective of the 2 proposed hybrid watermarking schemes is to increase the immunity of the watermarked 3DV to attacks and achieve adequate perceptual quality. The performances of the 2 proposed hybrid watermarking schemes are compared with those of the state-of-the-art watermarking schemes. The comparisons depend on both of the subjective visual results and the objective results; the peak signal-to-noise ratios of the watermarked frames and the normalized correlation of the extracted watermark frames. Extensive simulation results on standard 3DV sequences have been conducted in the presence of attacks. The obtained results confirm that the 2 suggested hybrid watermarking schemes are robust in the presence of attacks. They achieve not only very good perceptual quality with appreciated peak signal-to-noise ratio values but also high correlation coefficient values in the presence of attacks. beneficial to ensure copyright. A digital watermark can be embedded either in a compressed video or uncompressed video. 2 Video information are always transported and stored in the form of compressed data. The uncompressed video watermarking schemes can also be used for the compressed-video bit streams; however, they require complete video re-encoding and decoding for the watermark insertion or extraction. In different cases, the complete video stream decoding process is not recommended. So, the compressed video watermarking has recently acquired more attentiveness. Furthermore, the watermark insertion and extraction in compressed data has less computations, because the complete reencoding and decoding of the transmitted stream is not required for embedding and extracting the watermark bits.Recently, several video encoding standards have emerged. The objective of an encoding standard is to achieve high data compression, while maintaining an acceptable quality. The 3D multiview video coding (3D-MVC) is an efficient one of the recent encoding standards used in different applications. The 3D-MVC has received a broad attentiveness, and it is expected to rapidly take place of traditional 2D video coding in numerous applications. 3 In the 3D-MVC system, the original 3D video (3DV) consisting of multiple video streams is taken for the same object by various cameras. Thus, to transport the 3DV over limited resources networks, a highly efficient compression standard must be applied, whilst preserving a high reception quality. ...

“…With the rapid development of multimedia processing technologies, digital videos can be easily tampered, altered or forged by unauthorized users with video editing tools. Under these circumstances, authenticity and integrity verification of digital video becomes an important research topic nowadays [1]. Video watermarking technology provides useful solution for such problems by embedding the watermark information behind a cover [2,3,4,5].…”

Since video products compressed by H.264/AVC become increasing popular, issues of authentication for H.264/AVC-based video will be very important. In this paper, a content-based authentication semi-fragile watermarking scheme for H.264/AVC video is proposed. The content-based authentication code is generated using the invariance of the relation between DCT DC coefficients of the two 4×4 sub-blocks. The authentication code is then embedded into the DCT coefficients in diagonal positions in I frames. Spatial tampering can be located by comparing the extracted watermarking and the content-based authentication code. The experimental results show that the proposed scheme can distinguish the malicious spatial tampering from the common signal processing. The tampered areas can also be located
