Steganography is one of the methods of secret communication that hides the existence of message so that a viewer cannot detect the transmission of message and hence cannot try to decrypt it. It is the process of embedding secret data in the cover image without significant changes to the cover image. A cryptography algorithm is used to convert the secret messages to an unreadable form before emb...

Steganography is an ancient art of conveying messages in a secret way that only the receiver knows the existence of message. So, a fundamental requirement for a steganographic method is imperceptibility; this means that the embedded messages should not be discernible to the human eye. There are two other requirements, one is to maximize the embedding capacity, and the other is security. The lea...

Steganography is a branch of information security which deals with transmission of message without being detected. Message, to be send, is embedded in a cover file. Different types of digital can be used as cover object, we used (.WAV) audio as our cover file in the research work. The objective of steganography is to shield the fact that the message exists in the transmission medium. Many algor...

Steganography is one of the cryptography techniques where secret information can be hidden through multimedia files such as images and videos. offer a way exchanging encrypted in an untypical mechanism communicating parties only interpret message. The literature has shown great interest least significant bit (LSB) technique which aims at embedding message bits into most insignificant image pixe...

We present an information hiding technique that utilizes lifting schemes to effectively hide information in images. A successful information hiding should result in the extraction of the hidden data from the image with high degree of data integrity. Current trends favor using digital image files as the cover file to hide another digital file that contains the secret message or information. The ...

Several problems arise among the existing LSB-based image steganographic schemes due to distortion in a stegoimage and limited payload capacity. Thus, a proposed scheme has been developed with the aims to help in improving the payload of the secret data at the same time retaining the quality of the stego-image produced within an acceptance threshold. This study has led to the modification of th...

This research paper present a novel approach of Image based steganography scheme where a pseudorandom sequence generator function is used to randomize the mapping sequence in a pseudorandom fashion. The embedding process of the secret message is done according to the pseudo-random sequence, and extraction is done using the same sequence at the other end. At the base level, 2D-DCT is used to hid...

We present a novel technique for effective steganalysis of high‐color‐depth digital images that have been subjected to embedding by LSB steganographic algo‐ rithms. The detection theory is based on the idea that under repeated embedding, the disruption of the signal characteristics is the highest for the first embedding and de‐ creases subsequently. That is the marginal distortions due to repea...

In the paper, for enhancing the security of the traditional LSB matching, two improved LSB-matching methods are proposed. In the steganograhical procedure, the Markov chain distance based on the second-order statistics is chosen as the security metric to control the modification directions of ±1 embedding. The first method is based on stochastic modification, which directly determines the modif...

We present a novel reversible (lossless) data hiding (embedding) technique, which enables the exact recovery of the original host signal upon extraction of the embedded information. A generalization of the well-known LSB (least significant bit) modification is proposed as the data embedding method, which introduces additional operating points on the capacity-distortion curve. Lossless recovery ...
