Improved Steganographic Method Preserving Pixel-Value Differencing Histogram with Modulus Function
We herein advance a secure steganographic algorithm that uses a turnover policy and a novel adjusting process. Although the method of Wang et al. uses Pixel-Value Differencing (PVD) and their modulus function provides high capacity and good image quality, the embedding process causes a number of artifacts, such as abnormal increases and fluctuations in the PVD histogram, which may reveal the ex...
متن کاملA high quality steganographic method with pixel-value differencing and modulus function
In this paper, we shall propose a new image steganographic technique capable of producing a secret-embedded image that is totally indistinguishable from the original image by the human eye. In addition, our new method avoids the falling-off-boundary problem by using pixel-value differencing and the modulus function. First, we derive a difference value from two consecutive pixels by utilizing th...
متن کاملA steganographic method for images by pixel-value differencing
A new and efficient steganographic method for embedding secret messages into a gray-valued cover image is proposed. In the process of embedding a secret message, a cover image is partitioned into non-overlapping blocks of two consecutive pixels. A difference value is calculated from the values of the two pixels in each block. All possible difference values are classified into a number of ranges...
متن کاملAn Enhanced Image Steganographic Method with High Payload Capacity using Multidirectional Block Based Pixel-Value Differencing
To increase the payload capacity of the hidden secret information and to provide an imperceptible stegoimage for human vision, an enhanced steganographic method using multidirectional block based pixel-value differencing is proposed in this paper.To enhance the hiding payload capacity in image an steganographic method based on three-pixel block differences by Lin and Hseuh referring to only one...
متن کاملA Novel Image Steganographic Method Using Tri-way Pixel-Value Differencing
To enlarge the capacity of the hidden secret information and to provide an imperceptible stego-image for human vision, a novel steganographic approach using tri-way pixel-value differencing (TPVD) is proposed in this paper. To upgrade the hiding capacity of original PVD method referring to only one direction, three different directional edges are considered and effectively adopted to design the...
