Abstract: Steganography is the art of coveting data through which the sensitive information can be secured by covering it through a compatible media. Steganegraphy focuses on the existence of the cover media through which the data can’t be accessed illegitimately. The paper provides a spectral view on the basic implementation and the various steganographic techniques. Here we profoundly deal with transmission techniques of tender data so as to make the system more reliable and robust.
Keywords: Steganograpgy, LSB, DCT, DWT, CNF, GNF, PSNR, Pseudorandom sequence.
