At present, most of the reversible data hiding (RDH) algorithms divide images into regular
rectangular blocks for data embedding, and most of the RDH algorithms for color images …

Image steganographic communication demands a fair trade-off among the three
diametrically opposed metrics such as higher capacity, larger visual quality, and attack …

Reversible data hiding is a data-hiding technique which has the ability to recover the
original version from stego-images after the secret information is extracted. In this paper, we …

In recent years, transmitting and sharing multimedia data across the Internet have raised up
many data security issues such as copyright and contents protection due to the …

In this paper, we propose a partial reversible data hiding scheme using (7, 4) Hamming
code (PRDHHC) with secret position (κ). In this scheme, we partition the original cover …

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

Reversible data hiding can restore the original image from the stego image without any
distortion after the embedded secret message is exactly extracted. In this paper, a novel …

Reversible Data Hiding (RDH) should be secured as per requirements to protect content in
open environments such as the cloud and internet. Integrity and undetectability of …

Generally, irreversible and reversible image steganography use the concept of encryption to
produce a higher level of security. In this case, the payload is encrypted before embedding …
