Digital Image Watermarking to Hide the Text Message by using Graphics Interchange Format (GIF)

Digital Watermarking is one of the most popular technology to preserve and secure the digital copyright of multimedia data. In the steganography concept, it is used to hide message or watermark into data in order to keep it secret and avoid attention from others. In the Discrete Cosine Transform (DCT) and Discrete Wavelet Transform (DWT) algorithm mainly used to hide the secret message using the Graphical Interchange Format (GIF). In the cover image (GIF) to insert a watermark, it is used to achieve high robustness and imperceptibility. The proposed method has been implemented in MATLAB and the experimental results show that is quite satisfactory under various categories of attacks.
