Abstract
Steganography is a form of security technique through obscurity, the science and art of hiding the existence of a message between sender and intended recipient. The techniques used in Steganography make it difficult to detect that there is a hidden message inside an Image file. The identity information is encrypted by using the LSB technique on BMP images. Original and stego-images after the embedding process are compared to each other and the robustness of the application against steganalysis attacks is measured using SHADE tool. Various image Steganography techniques have been proposed. In this study, the aim and application areas of Steganography and steganalysis are briefly described. Kinds of techniques used in Steganography are analyzed and compared to each other according to their simplicity and robustness. Different applications have different requirements of the Steganography technique used. This paper intends to give an overview of image Steganography, its uses and techniques.
