“…In common, for data hiding, existing solutions rely on hiding message bits in Discrete Cosine Transformation (DCT) coefficients [4] [5], Motion Vectors (MVs) [6], [7] and [8], quantization scale [9] or prediction modes. Data hiding can also be applied before compression.…”

“…Nakajima et al proposed a high carrier capacity data hiding method in MPEG domain utilizing the idea of zerorun-level encoding [5]. After zigzag scanning, a dummy nonzero value is inserted at a location that is x units away from the original last nonzero qDCTC, where x depends on the data to be embedded.…”

This paper proposes an efficient data representation scheme to improve the performance of a data hiding method [1] in MPEG compressed domain. Even though [1] completely preserves the quality of the modified video to that of the original (compressed) video and [1] is reversible, [1] suffers from consistent filesize increase caused by data embedding. To suppress filesize increase, reverse zerorun length (RZL) is proposed to efficiently encode the message. RZL utilizes the statistics of the macroblocks with respect to [1], and the distance between two excited macroblocks is considered to encode a message segment. RZL simultaneously achieves high payload and high embedding efficiency, thus RZL is able to suppress the filesize increase caused by data embedding. We theoretically analyzed that RZL outperforms matrix encoding for both payload and embedding efficiency for this particular data hiding method. Experiments are also carried out to verify the theoretically deduced results, and the observed results agree with the expected outcomes.

“…The information is hidden using the motion compensation block sizes of an H.264/AVC video. Early video data hiding techniques extended to video by hiding the message in each frame independently [4]. Methods such as spread spectrum are used, where the basic idea is to distribute the message over a wide range of frequencies of the host data.Transform domain is generally preferred for hiding data in the videos.…”
