Data hiding in images using Hybrid Fractal Wavelets

Shifali Singla Abstract— Image Steganography is the art of hiding message into a cover image. This paper presents a novel technique for image steganography based on DWT, where DWT is used to transform original image (cover image) from spatial domain to frequency domain. This paper reviews about the art of writing hidden messages in such a way that no one apart from intended destination knows that a message has been sent. Steganography is defined as an art of hiding information and used in order to offer means of secret communication between two parties. It adopts both fractal and wavelet image processing techniques. BER and PSNR of cover image with stego-image shows the better results in comparison with other existing steganography techniques. Implementation is done in Matlab Software.
