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 letter suggests an alternative scheme which is not only secure against projection attack but allows also the insertion of arbitrary watermarking sequences.

Abstract
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 letter suggests an alternative scheme which is not only secure against projection attack but allows also the insertion of arbitrary watermarking sequences.File in questo prodotto:
