“…In [100,102,199,204], the authors investigated double compression detection using encoding parameters in H.264 bitstreams. In [102,[205][206][207], the authors used encoding parameters in H.265 video bitstreams for double compression detection. Altinisik et al used both encoding parameters and video container metadata for video device attribution, which resulted in improved performance compared to methods using container metadata only [208].…”

In this paper, we review recent work in media forensics for digital images, video, audio (specifically speech), and documents. For each data modality, we discuss synthesis and manipulation techniques that can be used to create and modify digital media. We then review technological advancements for detecting and quantifying such manipulations. Finally, we consider open issues and suggest directions for future research.

In recent years, video forensic investigation has become a prominent research area, due to the adverse effect of fake videos on networks, people and society. This paper summarizes all the existing methodologies used for forgery detection in H.265/HEVC videos. HEVC video forgery is generally classified into two categories as video quality forgery and video content forgery. The occurrence of various forgeries such as transcoding, fake-bitrate, inter-frame forgery and intra-frame forgery is deeply analyzed based on features extracted from the HEVC compression domain. The major findings of this research are (i) Less focus on transcoding detection, (ii) Non-availability of HEVC forged video dataset (iii) More focus on double compression detection for forgery detection, and (iv) Non-consideration of adaptive-GOP structure. The forgery detection in the video is critically important due to its wide use as the primary source of information in criminal investigations and proving the authenticity of contents. So, the forgery detection accuracy is of major concern at the present time. Although, various forgery detection methods are developed in past but the findings of this review point out the need of developing more effective detection methods with high accuracy.

“…1.2 Frequency domain: in this domain, there are many common approaches, such as Discrete Sine Transform (DST) and Discrete Cosine Transform (DCT). Despite that the watermarking techniques in this domain are highly robust, they still suffer from high complexity issues [1,12,18,41,42]. They are commonly used for both copyright and authentication applications due to their high robustness against unintentional attacks.…”

“…In 2015, Huang et al [14,32,42] presented a technique for distinguishing double compression attacks by analyzing the distribution of NNZ coefficients for the smooth regions of video frames. Specifically, it calculates the difference between the frequency of residual coefficients of the first and second compressions.…”

Recently, High-Efficiency Video Coding (HEVC/H.265) has been chosen to replace previous video coding standards, such as H.263 and H.264. Despite the efficiency of HEVC, it still lacks reliable and practical functionalities to support authentication and copyright applications. In order to provide this support, several watermarking techniques have been proposed by many researchers during the last few years. However, those techniques are still suffering from many issues that need to be considered for future designs. In this paper, a Systematic Literature Review (SLR) is introduced to identify HEVC challenges and potential research directions for interested researchers and developers. The time scope of this SLR covers all research articles published during the last six years starting from January 2014 up to the end of April 2020. Forty-two articles have met the criteria of selection out of 343 articles published in this area during the mentioned time scope. A new classification has been drawn followed by an identification of the challenges of implementing HEVC watermarking techniques based on the analysis and discussion of those chosen articles. Eventually, recommendations for HEVC watermarking techniques have been listed to help researchers to improve the existing techniques or to design new efficient ones.
