Abstract: |
As digital media proposes numerous benefits such as compression of data, easy editing, high reliability copying, high quality etc. So, data hiding is becoming a most important part of digital communication. Steganography and watermarking bring a variety of very significant techniques how to hide important information in an imperceptible and/or irremovable way in image, audio and video data. Steganography and watermarking are main part of the fast emerging area of information hiding. In this paper, we have discussed both watermarking and steganography techniques using different transform i.e. discrete cosine transform (DCT), discrete wavelet transform (DWT) and discrete fraction Fourier transform (DFrFT) for biomedical images to achieve the enhancement in confidential and authenticated data storage and secured transmission. Peak Signal to Noise Ratio (PSNR) is used as a performance index to show the quality of watermarked image and steganographic image. |
