“…The performance of the proposed method is measured for PSNR, PFF, and FPP as before. The simulation results of the proposed method are compared with those of [10][11][12][13] as shown in Table 4. The performance of [10,11,13] is much lower than the proposed method just because the pseudo RDH method is used, apart from their own algorithms.…”

The performance of [10,11,13] is much lower than the proposed method just because the pseudo RDH method is used, apart from their own algorithms. For fair comparison, the genuine RDH method suggested in [12] is applied to those methods.…”

“…However, those are located in the low frequency region instead of the medium frequency region, resulting in relatively high distortion in the stego video. Bouchama et al [11] devised a mapping table that maps three bit long secret messages into four QDCT coefficient values in the mid-frequency region. With this approach, the data hiding capacity is increased, and PSNR is improved about 0.44 dB compared to the method in [9] that can hide two bits per 4 × 4 QDCT block.…”

“…With this approach, the data hiding capacity is increased, and PSNR is improved about 0.44 dB compared to the method in [9] that can hide two bits per 4 × 4 QDCT block. Kim et al [12] hid the secret message in the same location as [11], but they was able to hide up to four bits per block and the number of hidable blocks increased compared to [11]. In addition, the distortion caused by data hiding is suppressed by the compensation effect that can happen in specific conditions.…”

“…We need at least 2 m histogram vacant bins to accommodate m bits. According to the result of [11,12], the most appropriate positions for the data hiding are r 7 through r 10 , taking into account the three main objectives of a RDH technology: larger payload, less distortion, and smaller bitstream increase. In this medium frequency range, the results are generally not biased between the aforementioned three contradictory goals.…”

Video has become the most important medium for communication among people. Video has become the most important medium for communication among people. Therefore, reversible data hiding technologies for video have been developed so that information can be hidden in the video without damaging the original video in order to be used in the copyright protection and distribution field of video. This paper proposes a practical and genuine reversible data hiding method by using a multi-dimensional histogram shifting scheme on QDCT coefficients in the H.264/AVC bitstream. The proposed method defines the vacant histogram bins as a set of n-dimensional vectors and finds the optimal vector space, which gives the best performance, in a 4 × 4 QDCT block. In addition, the secret message is mapped to the optimal vector space, which is equivalent to embedding the information into the QDCT block. The simulation results show that the data hiding efficiency is the highest among the compared five existing methods. In addition, the image distortion and maximum payload capacity are measured quite high.
