Abstract:
Steganography is the art of hiding information in ways that prevent the detection of hidden messages. It includes a vast array of secret communications methods that conceal the message’s very existence. These methods include invisible inks, microdots, character arrangement, digital signatures, covert channels, and spread spectrum communications. Steganography and cryptography are cousins in the spy-craft family. This paper information hiding and its applications, and image compression using proposed efficient encoding technique with the main focus being on hiding in the spatial domain are developed. Three information hiding methods are proposed, which are based on the encoding technique, are tested and the results are analyzed. Increase in tolerance level would allow using all range blocks so that more data can be stored. However low tolerance is desirable in order to give an image that is visually close to the original. Further research should go towards improving the watermarking program and adding extra functionality. One of these is looking at having multiple watermarks for a single image, so that different parts of the image have a different watermark. There is also the need to further develop the robustness of existing watermarking techniques to combat the ever-increasing attacks on watermarks. We used fixed partitioning scheme. Instead of this, adaptive partitioning scheme can be used, which would yield better results if used as the basis for the data hiding method.
