摘要：Asymmetric watermarking scheme enable one can detect public watermark. Watermark detection doesn’t need secret key or original multimedia data. Watermark detection done by doing correlation test between public keys and data multimedia tested. Usually scheme, private key is watermark inserted; public key is public key that correlated with private watermark. In this paper presents asymmetric watermarking scheme concept that based on correlation test, and continue with review some asymmetric watermarking proposals that already publish.
