Existing image-based reversible data hiding (RDH) methods tend to focus on increasing
embedding capacity, but few consider keeping or improving visual image quality. Wu et al …

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 …

In this work, a novel hybrid algorithm has been developed for achieving imperceptible and
robust image steganography for secure data communication. The novelty of the work lies in …

In this paper we present a model-based image steganography method in discrete wavelet
transform (DWT). This method is based on the human visual system model. The proposed …

Steganography aims to embed additional data into digital media secretly and minimize the
distortion caused by data embedding. Up to now, the key point of minimal distortion …

Privacy concerns with social media have recently been under the spotlight, due to a few
incidents on user data leakage on social networking platforms. With the current advances in …

Signal processing in the encrypted domain has attracted a lot of attention due to the
requirement for content security and privacy protection. Reversible data hiding in encrypted …

Generally, spatial domain and transform domain steganography techniques are used to
achieve the covert communication. The main drawback of embedding in frequency domain …

In this paper, a novel sparse recovery based reversible data hiding (RDH) method using the
human visual system (HVS) is presented. To improve the low accuracy of existing predictors …

Recent advances in network speeds for exchanging multimedia data over insecure networks
has resulted in an increased interest in steganography techniques. These techniques are …
