- W2372975120 abstract "A new algorithm for multiple watermarks based on DWT is proposed and the original image is not required for detecting the multiple watermarks.Using this algorithm,the original source is protected well.In this novel algorithm,we combine the cryptography with the conventional water marking methods——addition and quantization index modulation(QIM) together.When embedding the watermarks,different watermarks produce different secret keys associated with the embedded watermarks.When extracting the watermarks,different keys produce the different watermarks.The secret keys are then registered to the third party to protect the ownership of the original source.Many simulation experiments have been done,such as JPEG compression Gaussian noise,median filtering and image cropping.The simulation experimental results show that the embedded digital watermarks with the proposed algorithm are invisible and robust enough." @default.
