Some New Steganographic Techniques using Spatial Resolution Reduction
Journal Title: International Journal of Advanced Research in Computer Engineering & Technology(IJARCET) - Year 2013, Vol 2, Issue 1
Abstract
In this paper, we present four new techniques to hide a large volume of text in a gray level image by reducing its spatial resolution to its half, to its quarter and by reducing the spatial resolution in width and in height. The actual image and the data embedded stego-images using the techniques are given. The Mean Square Error (MSE) and Peak to Signal Noise Ratio (PSNR) values have been determined. Histograms for the computed values of MSE and PSNR indices and embedding capacity are drawn
