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
