Abstract : In today's modern era, networking primarily through internet plays a vital role in commercial applications, suck as internet banking, e-commerce, internet shopping etc. It becomes necessary in such applications to provide security to our confidential information that gets exchanged through these insecure channels. Our present work intends to hide and protect such sensitive information in an arbitrary background image without the sensitive data being exposed to public domains. Though many techniques exist for this purpose, our proposed method differs by embedding encoded sensitive information on a cover image, compressed and then transmitted to the destination. This provides greater security to the data transmission. This paper critically discusses the advantage of using Arithmetic coding technique and Bit Plane Substitution to derive the stego image. A detailed study is made to compare our technique with other prominent techniques like DCT and DWT.
