In this paper, a color image of encryption algorithm used a graph theory has been proposed.
The proposed algorithm depends on the audio files as a basis for exploiting a set of keys for …

In this paper, a simple reversible data hiding (RDH) scheme for embedding a great amount
of information in JPEG images is proposed. Non-zero JPEG quantized coefficients are …

Steganography is the science of secret communication. It assumes if message is visible then
it can be accessed. If it is invisible then it can never be in front of attack. So it hides the …

This paper presents a spatial steganography scheme with high steganography capacity for
medical images. In the proposed scheme, four least significant bits of the cover image are …

Steganography is the science of hiding data within data. Either for the good purpose of
secret communication or for the bad intention of leaking sensitive confidential data or …

Data hiding is referred as a famous and effective technique for delivering secret message
securely, in which the secret message is concealed in a cover medium during transmission …

Achieving an efficient and accurate steganography scheme for hiding information is the
foremost priority in the information and communication technology era. The developed …

This study examines the lossless compression of an original JPEG bitstream such that spare
space is reserved to embed secret data in a file header. After an original image is …

This paper proposes a reversible data hiding (RDH) method based on the absolute moment
block truncation coding (AMBTC) compression technique and Huffman coding. First, AMBTC …

A reversible data hiding scheme in JPEG compressed bitstreams is proposed, which could
avoid decoding failure and file expansion by means of removing of bitstreams …
