| This paper presents an asymmetric watermarking technique derived from Barni algorithm, a symmetric watermarking technique, using statistical approach. This asymmetric version 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 encrypted version of a secret sequence. The detection process is implemented by correlation test between the public watermark and the received image. Experiments show that the asymmetric technique was proved as robust as its symmetric version against some typical image processings. |
