Steganography is derived from the Greek word stenographic, which means covered writing. It is the science of secret communication. The goal of steganography is to hide the existence of the message from unauthorized party. The modern secure image steganography presents a task of transferring the embedded information to the destination without being detected by the attacker. The new security conception hides secret information within the LSB of image where a secret key encrypts the hidden information to protect it from unauthorized users. In general, in LSB methods, hidden information is stored into a specific position of LSB of image. For this reason, knowing the retrieval methods, anyone can extract the hidden information. In this paper, I purposed an image based steganography that Least Significant Bits (LSB) techniques and pseudo random encoding technique on images to enhance the security of the communication. A particular image is selected as the cover image and then, any secret message of any size is hidden into the image. Also, the hidden image can be decrypted using this project. Not only this, the project is able to study the change in image properties when exposed to two different algorithm; Bitwise and X-OR algorithms
