Abstract: Image Steganography is mainly used for hiding an image or secret message in a cover image. For data hiding this technique is being widely used for so many years. Image steganography is being used now by government, individual sender and receiver, in business and in so many fields. Now-A-Days this process has become very popular worldwide. People are doing research on image steganography and inventing new algorithms for image steganography. Hiding data in cover image by modifying bits of that is now optimized by so many new algorithms. Enthusiastic people are increasing demand of researching on image steganography and developing pc software and mobile application using different developing tools, programming languages and their own invention, algorithms etc. Images are the most widespread carrier medium. They are used for steganography in the following way. The message may firstly be encrypted. They’re used for steganography in the following way. The message may firstly be encrypted. The sender embeds the secret message to be sent into a graphic file. This results in the production of what is called steganography-image. Additional secret data may be needed in the hiding process e.g. a steganography key etc. This steganography-image is then transmitted to the recipient.
