A Secure Data Hiding Scheme for Two-Color Images
نویسندگان
چکیده
In this paper, we propose a new steganography scheme for hiding a piece of critical information in a host binary image (such as facsimiles). A secret key and a weight matrix are used to protect the hidden data. Given an image block of sizem n, our scheme can hide as many as blog2(mn+ 1) bits of data in the image by changing at most 2 bits in the image. This scheme, as compared to an existing scheme [18], can provide higher security, embed more data, and maintain higher quality of the host image.

A Novel Color Image Hiding Scheme Using Block Truncation Coding
In this paper, a novel color image hiding scheme that is capable of hiding two color secret images into a color host image is proposed. The secret images to be embedded are first compressed by the single bit map block truncation coding. DES encryption is then conducted on the compressed message before the secret image is embedded into the rightmost 3, 2, 3 bits of the R, G, B channels of every ...
متن کاملA new steganographic method for color and grayscale image hiding
In this paper, we present a steganographic method for embedding a color or a grayscale image in a true color image. Three types of secret images can be carried by the proposed method: hiding a color secret image, hiding a palette-based 256-color secret image, and hiding a grayscale image in a true color image. Secret data are protected by the conventional crypto system DES. We compare the image...
متن کاملA Reversible Data Hiding Scheme Based on Histogram Modification in Integer DWT Domain for BTC Compressed Images
Reversible data hiding is an efficient way for embedding additional data into cover media, which can reversibly recover the original cover media when the additional data is extracted. It has been widely utilized in secure communication and copyright protection. A reversible data hiding scheme imposed on the quantized coefficients of compressed images based on block truncation coding (BTC) is pr...
متن کاملA High Capacity Data Hiding Approach for Color Images
Steganography is the art and science of hiding secret data information in other media like digital images. The secret message is hidden in such a way that no one can apart from the sender or the intended recipient view the information. Therefore, different techniques have been proposed so far for. This paper introduces a hybrid approach of data hiding for color images based on 3 LSB technique a...
متن کاملAn Improved Reversible Data Hiding Scheme Using Extra Space Modulation for Color Palette Image
In this paper, a reversible data hiding scheme for color palette image is proposed. The technique of data embedding is used to hide the secret data into multimedia such as text contents, audio, video, and images. The reversibility of data hiding is an important requirement in some applications such as distance medical treatment and military industrial applications. In recent years, many researc...
