Untuk perlindungan hak cipta, isyarat tera air dibenamkan dalam imej hos dengan kunci rahsia dan korelasi digunakan untuk menilai kehadiran isyarat tera air dalam pengesanan tera air. Kertas ini menangani kaedah penanda air imej berasaskan transformasi wavelet (DWT) di bawah kebarangkalian positif palsu yang ditentukan. Kami mencadangkan kaedah penanda air baharu untuk meningkatkan prestasi pengesanan dengan menggunakan bukan sahaja korelasi positif tetapi juga korelasi negatif. Juga kami membentangkan analisis statistik untuk prestasi pengesanan dengan mengambil kira kebarangkalian positif palsu dan membuktikan keberkesanan kaedah yang dicadangkan. Dengan menggunakan beberapa keputusan percubaan, kami mengesahkan analisis statistik dan menunjukkan kaedah ini berfungsi untuk meningkatkan kekukuhan terhadap beberapa serangan.

Abstract: For copyright protection, a watermark signal is embedded in host images with a secret key, and a correlation is applied to judge the presence of watermark signal in the watermark detection. This paper treats a discrete wavelet transform (DWT)-based image watermarking method under specified false positive probability. We propose a new watermarking method to improve the detection performance by using not only positive correlation but also negative correlation. Also we present a statistical analysis for the detection performance with taking into account the false positive probability and prove the effectiveness of the proposed method. By using some experimental results, we verify the statistical analysis and show this method serves to improve the robustness against some attacks.
