Abstract
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 watermark. The number is embedded in the frequency domain using the discrete wavelet transform. On the other hand, hash codes are used as fragile watermarks and inserted in the spatial domain of the RGB image. The scheme is blind and the extraction process of the watermarks (Robust and Fragile) does not require the original image. The fragile watermark can detect any tampering in the image while the robust watermark is strong enough to survive against several attacks. The watermarking algorithm causes minimal distortion to the images. The proposed algorithm has been successfully tested, evaluated and compared with other algorithms.
