DATA CONCEALING IN GRAYSCALE IMAGES SPATIAL DOMAIN
In this article we are proposing one approach to concealing information in images. This approach uses the redundancy in grayscale image model to make up data vessels. To initiate this approach we are implementing subband analysis which allows us to determine power components and change them, constructing data vessels, in spectral domain with high fidelity.
