A Simple PN Sequence Based Steganography for Images: Spatial Domain and DCT Domain Performances
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 …

A Detail Survey on Image Steganography Techniques and Applications
Abstract: Steganography is working to achieve its significance owing to the growth and underground communication of possible computer operators on the internet. It may be distinct like the knowledge of unnoticeable communication that usually agreements with the methods of concealed occurrence of the interconnected message. The concealed information can be text, image, sound file, movie file, etc. In image steganography, undisclosed communication is attained to insert a message into protected image …
