Introduction:In this study, ECG signals have been embedded into medical images to create a novel blind watermarking method. The embedding is done when the original image is compressed using the EZW algorithm. The extraction process is performed at the decompression time of the watermarked image. Materials and Methods: The multi-resolution watermarking with a secret key algorithm developed in th...

In this paper, the authors propose a new key generation algorithm based on using a binary image. The proposed algorithm converts 16×16 binary array representing the digital image into 4×4 array, then it converts the new generated array into 4×4 decimal array. The decimal array and the left diagonal of the original array are then used to generate the public key that is used to encrypt the data t...

Many approaches and techniques are available in the literature for information hiding. Figure 1 shows a generic embedding and extracting scheme. The inputs to the embedding scheme are the hiding message, the cover data and an optional public or secret key K. The output is stego data, also called stego object. Inputs to the generic extracting scheme are the tested data, the secret or public key,...
