Steganography is the science of hidden writing schemes in which the presence of concealed information is not noticeable. It is a gifted approach for secure electronic communication and transmission of secret data safely over the internet. This paper is the detailed experimental analysis and review of “Grey Level Modification Steganography for Secret Communication”. Analysis is based on popular image quality measures, security analysis, visual analysis, bit plane analysis and worst case situation. Experimental result of selected method of steganogrphgy is compared with the basic Least Significant Bit substitution and Least Significant Bit matching method of steganography. All these results are checked for both the color and grayscale images. Moreover this review and analysis could be a deep understanding of most popular and simple steganography method such as Grey Level Modification, Least Significant Bit substitution, Least Significant Bit matching etc and will be a helpful analysis for presenting new approaches in this field.
