Modified BCH data hiding scheme for JPEG steganography
In this article, a new Bose-Chaudhuri-Hochquenghem (BCH)-based data hiding scheme for JPEG steganography is presented. Traditional data hiding approaches hide data into each block, where all the blocks are not overlapping each other. However, in the proposed method, two consecutive blocks can be overlapped to form a combined block which is larger than a single block, but smaller than two consec...
متن کاملA Reversible Data Hiding Scheme for JPEG Images
When JPEG images are used as cover objects for data hiding, many existing techniques require the images to be fully or partially decompressed before embedding. This makes practical application of these methods limited. In this paper, we investigate ways to hide data in the compressed domain directly and efficiently, such that both the original content and the embedded message can be recovered a...
متن کاملA high capacity lossless data hiding scheme for JPEG images
In this paper, we propose a new high-capacity reversible data hiding method for JPEG-compressed images. This method is based on modifying the quantization table and quantized discrete cosine transformation (DCT) coefficients. Some elements of the quantization table are divided by an integer while the correvailable online 1 April 2013 eywords: nformation hiding eversible data hiding ossless steg...
متن کاملSpatial-spectral Watermarking Scheme for Jpeg Steganography
Steganography is the art of concealing the presence of a communication, across an open channel, from undesired parties. This is achieved by the encoding of message data in innocuous cover objects, such as JPEG digital images. Many JPEG steganography algorithms exist; most perform the encoding in the spectral domain of the image. A new steganographic method, deemed the Spatial-Spectral Watermark...
متن کاملImage Steganography using Inverse Embedding Reversible Data Hiding Scheme
Image steganography is a technology that communicates the secret data by the carrier image. A quality data hiding scheme should hide huge secret data in the carrier without demeaning the quality of the carrier. This paper, discusses a high hiding capacity reversible data hiding scheme with low distortion. It incorporates double-embedding strategy projected for storing secret data in carrier. Th...
