標題: | An Asymmetric Subspace Watermarking Method for Copyright Protection | 作者: | Tzeng, Jengnan Hwang, Wen-Liang Chern, I-Liang |
關鍵字: | Asymmetric watermark;copyright protection | 公開日期: | 二月-2005 | 起(迄)頁: | 784-792 | 來源出版物: | IEEE TRANSACTIONS ON SIGNAL PROCESSING 53 | 摘要: | We present an asymmetric watermarking method for copyright protection that uses different matrix operations to embed & extract a watermark. It allows for the public release of all information, except the secret key.We investigate the conditions for a high detection probability, a low false positive probability, & the possibility of unauthorized users successfully hacking into our system. The robustness of our method is demonstrated by the simulation of various attacks. |
