Peak signal to noise ratio (PSNR) and structural index similarity (SSIM) are two measuring
tools that are widely used in image quality assessment. Especially in the steganography …

Sending image in a plain form has a high risk for the data being vulnerable to steal. Thus,
due to reducing the risk, data security techniques should be implemented. Data security …

Authentication of digital media has been done with the various scheme, one of them is a
digital signature. The main reason the technique of digital signature appears on the …

This article introduces a robust image watermarking primarily founded on DWT (discrete
wavelet transform), BEMD (bi-dimensional empirical mode decomposition), DCT (discrete …

In this paper, a novel scheme for quantum image watermarking based on novel enhanced
quantum representation of digital images (NEQR) is proposed which can embed a 2 n-1× 2 …

Reversible Data Hiding in Encrypted Image (RDHEI) schemes may redistribute the data
hiding procedure to other parties and can preserve privacy of the cover image. Recently …

In the current era of globalization, security is one of the most important aspects in the
development of communication applications, especially when sending confidential files …

The popular LSB technique is used in steganography techniques on spatial domains. This
technique has many advantages in terms of imperceptibility and payload. Except in the case …

Watermarking is a copyright protection technique, while cryptography is a message
encoding technique. Imperceptibility, robustness, and safety are aspects that are often …

One popular security technique used to protect copyright ownership in digital images is
image watermarking. Discrete Cosine Transform (DCT) and Discrete Wavelet Transform …
