A Survey of Image Steganography (original) (raw)

Image Steganography is the art of hiding information within an image which is implied to act as a carrier image[14]. The secret message to be transmitted is then encrypted within this carrier image with a secret shared key. This process is achieved by changing the LSB of the pixels within the image to the bits of the data. Multiple algorithms have been suggested which offer different techniques to carry out the steganographic process. Some techniques that we have researched are the Enhanced LSB, F5, JSteg/JPHide and YASS. This paper outlines the proposed benefits and limitations of these techniques and suggests a suitable technique to carry out the steganographic process.
