With the quick progress and extensive use of internet, information transmission faces confronts of security and unauthorized access of secret data. In this situation steganography is considered as gifted approach. Steganography is the science of hidden writing schemes in which the presence of concealed information is not noticeable. This paper is the detailed experimental analysis and review of “Increased Capacity of Information Hiding in Least Significant Bit Method” of steganography. Analysis is based on popular steganalysis tools, image quality measures, security analysis and worst case situation. Experimental result of selected method of steganography is compared with the basic LSB substitution method, direct LSB substitution for two bits, for three bits and for four bits. The results shows the clear evidences of the fact that increased capacity method have preference over the direct LSB substitution, two bit substitution, three bits substitution and four bits substitution. All these results are checked for both the color and grayscale images. Moreover this review and analysis could be a deep understanding of steganography and will be a helpful analysis for presenting new approaches in this field.
