A Steganographic Method Based on Pixel-Value Differencing and the Perfect Square Number
The pixel-value differencing (PVD) scheme uses the difference value between two consecutive pixels in a block to determine how many secret bits should be embedded. There are two types of the quantization range table in Wu and Tasi’s method. The first was based on selecting the range widths of [8, 8, 16, 32, 64, 128], to provide large capacity. The second was based on selecting the range widths ...
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 کاملA Blind Detection Resistant Steganographic Algorithm for Images Based on Texture Complexity and Pixel-value Differencing
According to the analysis of the effect of the texture complexity on steganalysis, we propose a data hiding algorithm based on texture complexity and difference pixel value. Firstly, the image is decomposed into blocks, after which the texture complexity of each block is calculated and blocks with high complexity are selected. Then the different pixel values on two directions of the selected bl...
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 Steganographic Method by Pixel-Value Differencing and Exploiting Modification Direction
In this paper, we shall propose a new image steganographic scheme for embedding secret messages into a gray-valued cover image and capable of producing a secret-embedded image that is totally indistinguishable from the original image by the human eye. In addition, the proposed scheme avoids the falling-off-boundary problem by using the Pixel-Value Differencing (PVD) and the Exploiting Modificat...
