A new multiple watermarking scheme for medical images which is based on spatial and discrete cosine transform domains is developed. In this scheme, the radiologist can specify the regions of interest to be avoided during embedding. Two watermarks are embedded where the first one is robust for ownership protection and the second one is fragile for source authentication. In order to increase data robustness,...
A novel multiple watermarking scheme based on spatial and discrete cosine transform domains is proposed. The scheme allows the radiologist to define regions of interest to keep diagnostic value intact. The rest part of the image casts multiple watermarks conveying the patient's identification (ID) for ownership detection, and additional information for the purpose of integrity control and source authentication...
This paper examines and evaluates a new robust and fragile watermarking scheme for colour images captured by mobile phone cameras. The authentication has been checked by using the fragile watermarking, while the copyright protection has been examined by using the robust one. The mobile phone number, including the international code, is a unique number across the whole world and it is used as a robust...
This paper deals with a watermarking scheme for images captured by mobile phone cameras. The new scheme embeds two watermarks in the images for authentication checking and copyright protection. The mobile phone number including the international code is used as the first robust watermark. The number is embedded using the discrete wavelet transform. Hash code of the image is used as a fragile watermark...
