| Abstract: | Due to the lightning development in digital communication through the international networks and all the multimedia works are released via internet, it’s an urgent need now to safeguard the data from cruel attacks. So securing data has become an important problem in this field. Image data protection is the essential part in communication and multimedia world. During storing and sharing, avoid third party access of data is the challenging thing. Delivering security of data is the clever work and art also. Multiple protection algorithms are applied in recent times. Data can be safeguarded by transforming the original image into an unfamiliar format, such as signals or sketches, making it incomprehensible to anyone. Steganography is the art of hiding information into a cover image. This paper presents a novel stegano graphic method for hiding a secret Image inside the cover image. It exploits the use of host data to hide a piece of information in such a way that it's indistinguishable to human spectator. It's garnering considerable attention these days because it doesn't bring awareness to the presence of its information. The major purposes of effective Steganography are High Embedding Capacity, Imperceptibility and Robustness. The proposed algorithm uses Discrete Cosine Transform (DCT) for cover image. The cover image is segmented into 8 * 8 blocks and DCT is applied on the picture. DCT algorithm is executed in frequency domain in which the cover image is converted from spatial domain to the frequency domain and is segmented into 8 * 8 blocks also the secret image data bits are fitted into the frequency elements of the cover image. It's observed that the proposed algorithm is more robust with better Mean Square Error (MSE), Peak Signal to Noise Rate (PSNR), Character Error Rate (CER) & Normalized coefficient. |
