In this paper, we present a novel hardware implementation of a watermarking system applied on the digital image. The proposed hardware system is based on the DWT (Haar discrete wavelet transform) on the first level of the decomposition. The watermark is hidden in the LH0 (mean frequency sub-band) in goal to get a maximum of the compromise between the visibility and the robustness factors against several...
This manuscript presents a watermarking method based on Discrete Wavelet Transform (DWT) and Singular Value Decomposition (SVD) with the Advanced Encryption Standard (AES) algorithm encryption applied on medical image. The proposed schema will be developed to increase the protection and robustness along with security. In our algorithm, after decomposing the original image into four sub-bands in the...
This work presents a new approach of a joint Watermarking/ Encryption algorithm applied in medical domain such as telemedicine, hence the need to keep the visual aspect of medical images and other conservation of the various substituted data. For hiding information, the proposed method uses the Discrete Cosine Transform (DCT) space. For more robustness, the Advanced Encryption Standard (AES) encryption...
