Popis: Images are scrambled generally for different purposes like information hiding and communicating data in secret manner so that even unauthenticated persons hack the data not be able to understand as it is not true data. A novel and secured image scrambling technique is being proposed here in which the original image values are shuffled through a specific chaotic sequence order which will act as key and pixel values which are also manipulated through created random grid map which acts as another key. Person with both correct keys can only unscramble the image to reveal the original image. This method is implemented on different bitmap and grayscale images. Performance of proposed algorithm is also done by performing certain tests and it is found to be proposed method which is giving very convincing, and scrambled image is not at all perceptible to the human eye.
