Secure Hybrid Robust Watermarking Technique for Medical Images

Secure Watermarking Technique for Medical Images with Visual Evaluation

This paper presents a hybrid watermarking technique for medical images. The method uses a combination of three transforms: Discrete Wavelet Transform (DWT), Discrete Cosine Transform (DCT), and singular value decomposition (SVD). Then, the paper discusses the results of applying the combined method on different medical images from eight patients. The images were watermarked with a small waterma...

A Hybrid Secure watermarking technique in Telemedicine

For healthcare applications, a hybrid multiple watermarking has been projected in this paper. For authentication and identity purpose, the projected scheme makes use of two watermarks, one in the form of text watermark which includes diagnostic information of the patient and the other image watermark includes the hospital logo. In order to improve the robustness performance of the scheme DWT, D...

Robust and Adaptive Watermarking Technique for Secure Authorship of Digital Images

A robust feature-based technique for watermarking frontal face images

We introduce a novel method for embedding and detecting a chaotic watermark in the digital spatial domain of color face images, based on localizing salient facial features. Simulation results prove the robustness of the method to several kinds of attack, such as compression, filtering, scaling, cropping and rotation.

An Efficient and Robust Hybrid Watermarking Scheme for Text-Images

Addressing fraud and illegal use of multimedia requires the development of more powerful and robust algorithms. One of the solutions that can contribute significantly to solve such problems can be found in the use of image watermarking. In image watermarking, a watermark is introduced within an image in order to protect it against illegal use. This paper proposes a new hybrid text-image waterma...
