  Abstract

This paper proposes a real-time forensicmarking technique based on the HEVC / MPEG-H Part.2(H.265). The proposed forensicmarking technology receives encoded video based on the HEVC, decodes the encoded bitstream using Entropy Coding(CABAC), approaches QTC(Quantized Transform Coefficients), selects the coefficient to insert the mark, and insert the mark using the XOR operation on the n-bits of the mark bitstring and the pseudo-random n-bits based on the key. The proposed method is forensicmarking technique that CABAC decoding and re-encoding without HEVC decoding and re-encoding process, and recover forensicmark by fast bit operation accessing from QTC domain. As a result of comparing with previous studies, PSNR showed higher value with higher quality and about 30dB difference at 2K (1440p). The insertion speed was 27 times for low quality (720p) and 9 times for high quality (1440p).
