Abstract

The development of video steganography has put forward a higher demand for video steganalysis. This paper presents a novel steganalysis against discrete cosine/sine transform (DCT/DST)-based steganography for high efficiency video coding (HEVC) videos. The new steganalysis employs special frames extraction (SFE) and accordion unfolding (AU) transformation to target the latest DCT/DST domain HEVC video steganography algorithms by merging temporal and spatial correlation. In this article, the distortion process of DCT/DST-based HEVC steganography is firstly analyzed. Then, based on the analysis, two kinds of distortion, the intra-frame distortion and the inter-frame distortion, are mainly caused by DCT/DST-based steganography. Finally, to effectively detect these distortions, an innovative method of HEVC steganalysis is proposed, which gives a combination feature of SFE and a temporal to spatial transformation, AU. The experiment results show that the proposed steganalysis performs better than other methods.

Summary

INTRODUCTION

Modern steganography is an art and science of covert communication. It is a technology that protect the secret data from discovered or theft (Mishra et al, 2015). Rabee et al (2017) presented a blind JPEG steganalysis based on DCT coefficients differneces, and Wang et al (2017) proposed a steganalysis to detect DCT-based data hiding methods for H.264/AVC videos Both of them are not specialized in detecting DCT/DST domain steganography algorithms for HEVC videos. From another aspect, many steganalysis methods developed by exploiting the spatial or temporal correlation in video stream have been proposed. Tasdemir et al (2015) proposed a HEVC steganalysis system utilizing temporal pixel correlation of videos It employed Accordion Unfolding (AU) transformation and detected pixel domain image steganography algorithms used on video frames.
