  • Abstract
    An asymmetric watermarking algorithm is presented, involving a private key for embedding and a public key for detection, joint with a suitable encryption scheme, thus achieving a double security level for digital data protection. A commutative scheme is designed based on linear algebra and on a secret random permutation, allowing both to cipher watermarked data and to mark encrypted data without interfering with the watermark detection process.
