Image steganography is the art of hiding data into an image by using secret key. This paper presents two techniques that combine most significant bit (MSB) as well least (LSB) based on a color (24bit for RGB). The presented study proposes novel method to (LSB and MSB) bits check MSB values replace from LSB with message. result this proposed made not affect quality stego -image resulting histogr...

In this study, a novel approach which uses combination of steganography and cryptography for hiding information into digital images as host media is proposed. In the process, secret data is first encrypted using the mono-alphabetic substitution cipher method and then the encrypted secret data is embedded inside an image using an algorithm which combines the random patterns based on Space Fillin...

The Internet as a whole does not use secure links, thus information in transit may be vulnerable to interruption as well. The important of reducing a chance of the information being detected during the transmission is being an issue in the real world now days. The Digital watermarking method provides for the quick and inexpensive distribution of digital information over the Internet. This metho...

Steganography is an art of disguising the fact that communication is going on by concealing information in other information. In general, the communication carrier can be files in many formats; however, digital images are the most common due to their frequent use on the Internet. This paper introduces an improvement on the standard least significant bit (LSB)-based image steganography technique...

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...

Video Steganography deals with hiding secret data or information within a video. In this paper, a hash based least significant bit (LSB) technique has been proposed. A spatial domain technique where the secret information is embedded in the LSB of the cover frames. Eight bits of the secret information is divided into 3,3,2 and embedded into the RGB pixel values of the cover frames respectively....

In this paper, we propose two algorithms based on the popular Bit Plane Splicing Least Significant Bit (LSB) Technique for secret data hiding inside images. One major disadvantage of Bit Plane Splicing LSB technique is its low hiding capacity which results in severe degradation of the cover image upon hiding large amount of data. The proposed algorithms overcome this issue by imposing hiding ru...

According to the research of LSB steganalysis, LSB steganography could destroy the distribution of 0 and 1 in the lowest bit planes, and this situation will cause the abnormality of histogram and asymmetry statistical, thereby left an opportunity that could be exploited to the steganalysis. From the view of steganalysis, this paper compared the two typical kinds of image scrambling methods whic...
