Javad Mohammadi Rad . Intensity Adaptive LSB Method Applying a Revised Matching. International Journal of Computer Applications. 70, 27 ( May 2013), 20-26. DOI=10.5120/12240-8468
This paper proposes a new steganographic algorithm in spatial domain. A filtering method selects some color components of pixelsin BMP cover imagesfor embedding according to their Most Significant Bits(MSB) value. The components whose MSB value isgreater than a particular threshold,are qualified and the other ones will be skipped. This mechanism makes the retrieval of embedded message possible. Moreover, a matching technique ensures the most possible closeness of new intensity generated in embedding process to its original value. Performance of proposed method is evaluated by some measures namely MAE, MSE,LMSE,LP-Norm, SNR, PSNR, and NCC according to which, proposed method offers up to 40% better results in some measures compared to two other methods; LSB and SLSB.
