Exploring LSB Substitution and Pixel-value Differencing for Block-based Adaptive Data Hiding
Khodaei and Faez proposed a new adaptive data hiding technique based on LSB substitution and pixel-value differencing. Their algorithm can embed a large amount of secret data while maintaining acceptable image quality. However, their proposed algorithm only has fixed embedding capacity. In addition, the derivation for three consecutive pixels in the boundary region is poorly manipulated using r...
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 کاملData Hiding Method Based on Graph Coloring and Pixel Block‘s Correlation in Color Image
An optimized method for data hiding into a digital color image in spatial domainis provided. The graph coloring theory with different color numbers is applied. To enhance thesecurity of this method, block correlations method in an image is used. Experimental results showthat with the same PSNR, the capacity is improved by %8, and also security has increased in themethod compared with other meth...
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 steganographic method for digital images with four-pixel differencing and modified LSB substitution
To improve the embedding capacity and provide an imperceptible visual quality, a novel steganographic method based on four-pixel differencing and modified least significant bit (LSB) substitution is presented. The average difference value of a four-pixel block is exploited to classify the block as a smooth area or an edge area. Secret data are hidden into each pixel by the k-bit modified LSB su...
