Data Protection is important now days but most pivotal is to protect the medium through which data can be transfer from one point to another. To work upon it many different techniques are designed and implemented one of the techniques is Steganography . Steganography originates from greek word which means covered writing / or concealing information with other non secret text [Wikipedia]. Later on research different sub techniques of Steganography presented like Image, Audio, Text, Video etc. which uses different embedding mechanism to embed secret data in secure medium to prevent it from intruder. The first process tries to overcome the Targeted Steganalytic Attacks. This paper discusses Statistical properties of Steganography. Whenever message embed in a medium its properties changes and the resulted stego image will not be same as parent image . The work mainly revolve around first order statistics based targeted attacks. This paper proposes algorithm which can preserve image after embedding.
