A Transformation Scheme for Deriving Symmetric Watermarking Technique into Asymmetric Version
Year: 2010
Type: article
Abstract: This paper proposes a transformation scheme for rendering the asymmetric watermarking technique into its asymmetric version. The asymmetric technique uses secret watermark as private key and public watermark as public key. The public watermark has a normal distribution and the private watermark is a linear combination of the public watermark and a secret sequence. The detection process is implemented by correlation test between the public watermark and the received image. The scheme is used to transform Barni Algorithm, a symmetric watermarking technique, into a asymmetric version. Experiments showed that the asymmetric technique was proved as robust as its symmetric version against some typical image processing schemes.
