A Simple PN Sequence Based Steganography for Images: Spatial Domain and DCT Domain PerformancesBy Aparna Unni, Shehin AU
Abstract: Image steganography is the art of hiding a secret image into another image, called a cover image. Secret image which is converted to a 1D vector is embedded to the cover image. The embedding mechanism is simply adding the bit. In spatial domain, each bit is added to theselected pixel values. The selection is based on a PN sequence generated. Similarly, in DCT domain, based on PN sequence, DCT coefficients …
