Judul Tesis       : “ Teknik Watermarking Citra Menggunakan Integer Wavelet Transform (IWT) dan Discrete Cosine Transform (DCT) Pada Domain Singular Value Decomposition (SVD)”

Pesatnya kemajuan teknologi mengakibatkan banyak karya intelektual yang berupa citra atau gambar memerlukan perlindungan hak cipta agar tidak disalahgunakan oleh pihak yang tidak bertanggung jawab. Salah satu metode yang efektif untuk melindungi hak cipta pada citra digital adalah dengan penggunaan teknik watermarking. Penelitian ini akan menginvestigasi teknik hibrida watermarking dalam meningkatkan robustness dengan Integer Wavelet Transform (IWT) dan Discrete Cosine Transform (DCT) pada domain Singular Value Decomposition (SVD). Kemudian mengevaluasi dan menvalidasi skema teknik yang diusulkan secara objektif dengan pendekatan Peak Signal to Noise Ratio (PSNR), Structural Similarity Index (SSIM), dan Normalized Correlation (NC), dan pengujian robustness teknik yang diusulkan dievaluasi dengan beberapa jenis serangan / attack. Hasil pengujian menunjukkan bahwa teknik watermarking yang diusulkan memiliki performa invisibility dan robustness yang baik dan meningkat dibandingkan penelitian sebelumnya. Penggunaan metode tersebut diharapkan dapat menjadi alternatif solusi penggunakan teknik watermarking dalam meningkatkan keamanan pada citra digital.
