Experimental Review of “Grey Level Modification” Steganography

Abstract

Classification, Analysis and Comparison of Non-Blind Image Quality Measure

“…For evaluating the results and performance, different operations are performed on the original, unmodified, input image and then these modified images are compared with input images for image quality. Operations include the following: [14,15,16,17,18,19,20]  LSB Matching [21]  LSB Substitution [22] …”

Dynamic Increased Capacity Approach Steganography in Spatial Domain

“…Bit plane analysis checks the visual inconsistency due to any change in the image pixel value. For the most popular methods including LSB substitution [1], LSB matching [2, 3], GLM method [5] etc. the visual inconsistency is clearly visible in least bit planes and for the robust increased capacity image steganography scheme, least two-bit planes show clear change.…”

“…In image steganography, histogram analysis is used as a steganography analysis tool for various steganography schemes. For LSB substitution [1], LSB matching [2,3], GLM method [5] etc., histogram creates the specific pattern. For the projected scheme, as the embedding is in dynamic style, so histogram cannot be used as the steganography analysis tool.…”

“…Comparative analysis of the projected method with the LSB substitution [1], LSB matching [2,3], increased capacity in spatial domain [4] and GLM [5] methods is summarized in terms of bit plane and histogram analysis as well as static versus dynamic, bits per pixel in Table 4. It is clear from the Table 4 that new proposed dynamic increased capacity approach is best in terms of embedding rate, visual analysis and histogram analysis.…”

“…Steganography is paradigm that conceals the secret data into some digital medium in such a way so its existence cannot be noticed by human perception [1][2][3][4][5][6][7][8][9], see the study [10] for a recent review. With the rapid advancement and use of internet as communication channel, steganography has become an important and valuable tool for secure communication between sender and recipient without the snooping of third person.…”
