This paper presents a novel greyscale image reversible data hiding scheme based on
exploiting modification direction (EMD) method. In this scheme, two 5-ary secret numbers …

This paper presents a reversible data hiding method which provides a high payload and a
high stego-image quality. The proposed method transforms a spatial domain cover image …

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 …

This paper proposes a multi-hider dual-image reversible data-hiding algorithm. Generating
dual stego images, the proposed algorithm provides a high embedding capacity, exhibits …

Purpose Steganography is a data hiding technique used in the data security. while
transmission of data through channel, no guarantee that the data is transmitted safely or not …

In this paper, we propose a reversible data hiding scheme using (5, 3) Hamming code. A
cover image is partitioned into blocks of five pixels. An adjusted (5, 3) Hamming code …

This paper proposed a high capacity reversible data hiding (RDH) scheme using three
steganographic images, on which three successive embedding phases are performed. An …

Secure reversible watermarking schemes are essential for image authentication and tamper
detection in medical, military and government applications. In this paper, a secure reversible …

Reversible data hiding enables the cover image to be restored from the stego image without
any loss after the secret message is extracted. In this paper, we proposed a novel reversible …
