This paper presents a lossless and reversible steganography scheme for hiding secret data
in each block of quantized discrete cosine transformation (DCT) coefficients in JPEG …

Reversible data hiding (RDH) technology is an effective means to ensure the secrecy of
information transmission. In particular, the interpolation-based RDH algorithm is widely used …

Lossless data hiding is a special type of data hiding technique that guarantees not only the
secret data but also the ability of cover media to be reconstructed without any distortion. A …

Lee and Huang proposed a dual-image reversible data hiding method to protect the
confidential data in 2011. The image quality obtained by the method is good because each …

In this paper, an innovative reversible dual image information hiding technique is proposed,
which utilizes the coordinate vectors generated by the original pixel pairs to hide secret …

Achievement of high-capacity data hiding with good visual quality is an important research
issue in the field of steganography. In this paper, we have introduced a new dual color …

Lu et al. proposed a dual imaging-based reversible hiding technique using LSB matching in
2015, two pixels as a group and LSB matching method is used to embed the secret …

Electronic records of a patient's health history are often shared among healthcare providers,
and patient data must be kept secure to maintain the privacy of patients. One way of doing …

Data hiding is the discipline of hiding information into digital media. A reversible
steganographic method allows to extract data from the stego file as well as to retrieve the …

Over the past few years many studies have proposed reversible data hiding schemes, but
few have been applied to binary images. Some studies have utilized spread spectrum …
