An improved asymmetric watermarking scheme suitable for copy protection

An improved asymmetric watermarking scheme suitable for copy protection

A major limitation of some recently proposed asymmetric watermarking techniques based on linear algebra lies in the strong dependence of the watermark on the original image. The present correspondence suggests an alternative scheme that not only is secure against projection attack but also allows th...

Zusammenfassung:A major limitation of some recently proposed asymmetric watermarking techniques based on linear algebra lies in the strong dependence of the watermark on the original image. The present correspondence suggests an alternative scheme that not only is secure against projection attack but also allows the insertion of arbitrary watermarking sequences
