An increasing number of spatial and frequency domain data hiding techniques have been
proposed to address the relatively low embedding capacities of image-based …

With the recent amelioration in digital communication and cloud storage, security remains a
concern. Even though cryptographic algorithms have been readily used, they have been …

This paper introduces a high capacity image hiding scheme with enhanced stego image
quality. This new hiding scheme utilizes a multiscale Laplacian pyramid of the cover image …

Steganography is the science of hiding a secret message in cover media, without any
perceptual distortion of the cover media. Using steganography, information can be hidden in …

Steganography is used for secret or covert communication. A graph wavelet transform‐
based steganography using graph signal processing (GSP) is presented, which results in …

Embedding capacities of steganographic information security systems have remained
relatively low due to the adverse effect on perceptibility, where researchers had to trade-off …

In the past decade, Deep Neural Networks (DNNs) have achieved breakthrough
collaborations in developing smart intelligent systems within the field of computer vision …

This paper investigates the embedding capacity limits of high-capacity data hiding in color
images based on a locally Adaptive-Region Discrete Cosine Transform (AR-DCT) frequency …

Steganography is the method of hiding secret message information in various cover media
like text, image, audio, video and others without raising suspicion to intruders about the …

In this work, we show how to hide a maximum of 8 bits of secret data into the pixel difference
value. Adjacent pixel pairs are chosen in a non-sequential manner in the spatial domain …
