Abstract

The word steganography is originally derived from Greek words which mean “Hidden Writing”. Due to the rapid growth of usage of internet over high bandwidth and low cost computer hardware has propelled the explosive growth of steganography. The objective of steganography is hiding the payload (embedded information) into the cover image such that the existence of payload in the cover image is imperceptible to the human beings . In this paper we worked on quality of stego - image. Stego image should have better data embedding capacity and should have small computational time.
