The reversible steganographic method allows an original image to be completely
reconstructed from the stegoimage after the extraction of the embedded data. The traditional …

In this paper, we propose an adaptive reversible steganographic scheme based on the just
noticeable distortion (JND). First, the JND value of each cover pixel is calculated using the …

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 …

The dual stego images based on data hiding has become popular in recent days. Since the
embedding rate in dual stego images is very high. This paper proposes a new data …

The stego-images generated by many existing hiding techniques are not economic in size,
and hence need compression. Unfortunately, compression usually destroys the secret …

The advances in Internet technology and digital image representation helped the user to
easily exchange the secret message. On Internet the transmission of the secret message is …

Steganography is the technique of embedding secret data to another multimedia type. A
reversible steganography scheme (RSS) uses image features to hide the secret data into the …

Digital image steganography algorithms usually suffer from a lossy restoration of the cover
content after extraction of a secret message. When a cover object and confidential …

The technique of reversible data hiding recovers the original image from a stego-image
without distortion after the hidden data are extracted. A natural image usually contains …

Steganography is a technique that allows confidential data to be delivered securely by
embedding the data into cover digital media. In this paper, we propose a simple …
