“…Researchers have presented hybrid methods to enhance watermarking performance in terms of imperceptibility and robustness. A scheme by Vo et al [10] demonstrated a robust hybrid image watermarking scheme based on DCT-SVD for stereo images. The watermark was embedded in the singular value of DCT-SVD.…”

Digital images can be easily copied or manipulated by irresponsible persons. The right property needs to be secured and protected from illegal copies and piracy. Digital watermarking is one of the solutions to protect the intellectual property of digital images. This paper proposed the adaptive scaling factor based on selected DWT-DCT coefficients of its image content. The adaptive scaling factor was generated based on the role of selected DWT-DCT coefficients against the average value of DWT-DCT coefficients. The watermark image was embedded by using a proposed set of rules that consider the adaptive scaling factor. The experimental results showed that the proposed scheme achieved high PSNR value of 47dB, SSIM value of about 0.987 and an embedded watermark resistance to several attacks in the watermarked image.

“…Reversible watermarking is a technique that is widely used to protect the rightful ownership of digital images. In this section, the article represents a robust hybrid watermarking scheme based on DCT and SVD for copyright protection of stereo images [8]. Based on the properties of the stereo image, the procedure of reversible watermarking first begins by finding similar blocks, which are based on the coefficients in the frequency domain.…”

Reversible data hiding is widely recognized as one of the most employed methods for copyright protection and data security. This technique involves embedding a unique piece of information, referred to as a watermark or secret data, without being detected by human or machine visual systems. Moreover, the original image is completely restored after embedded information is extracted by the recipient. Reversible data hiding technique has many vital applications, such as camouflage in communication to protect confidential information or embedding information into photos to protect digital image content. However, the problem with this technique is to maintain a good trade-off between imperceptibility and a higher bit embedding rate. This research provides a thorough review of existing methods of image steganography. Moreover, the paper also discusses the strategy to select different cover media for numerous applications in modern life.

“…RDH schemes are suitable in some sensitive scenarios, such as military, medical and forensic fields, where any permanent distortion is unacceptable, and the exact recovery of the original cover data is required. RDH schemes for digital images can be classified into three different domains, including: frequency, compression, and spatial domains [6][7][8][9][10][11][12][13][14][15][16][17][18].…”

“…In the frequency domain [6][7][8][9], the cover image is first transformed into frequency coefficients via various transform functions, i.e., discrete Fourier transform (DFT), discrete cosine transform (DCT), and discrete wavelet transform (DWT). In 2018, Vo et al [6] proposed a 2D HS-based RDH scheme.…”

Reversible data hiding is a data-hiding technique which has the ability to recover the original version from stego-images after the secret information is extracted. In this paper, we propose a novel reversible data-hiding scheme based on an enhanced reduced difference-expansion technique. In the proposed scheme, the original image is divided into non-overlapping quad-blocks for embedding data. Then, to enhance the security, the secret bits are encrypted based on the encryption key and a symmetry-based strategy. To improve embedding capacity further, two adjacent encrypted bits are converted into a corresponding decimal digit. Difference expansion (DE) technique is applied to embed a decimal form instead of a binary version. Moreover, to maintain the good image quality, the enhanced reduced difference-expansion technique is used to reduce the original difference values so that it is suitable for decimal embedding. The experimental results demonstrated that the proposed scheme has achieved better performance in comparison with previous solutions.
