dc.description.abstractWatermarking merupakan salah satu metode proteksi hak cipta yang bertujuan untuk menanggulangi penyebaran karya seseorang secara ilegal. Pada dasarnya, watermarking adalah proses penandaan suatu citra dengan pesan hak cipta atau signature yang secara rahasia disisipkan dalam citra namun tidak terlihat perbedaan antara citra asli dengan citra yang telah ditandai.Pada penelitian ini akan dilakukan perbandingan algoritma watermarking yang dilakukan pada kawasan wavelet dan Discrete Cosine Transform (DCT). Sebagai obyek penelitian digunakan citra warna sebagai citra host, sedangkan sebagai citra watermark digunakan citra biner dengan ukuran 1/16 citra host. Proses embedding dilakukanberdasarkan Human Visual System (HVS), sehingga diharapkan diperoleh watermark yang tidak kelihatan (invisible watermark). Proses embedding dilakukan dengan algoritma aditif. Pada kedua alihragam yang dikembangkan, watermark disisipkan pada komponen frekuensi tinggi citra. Wavelet yang digunakan dalam penelitian ini adalah wavelet db4. Sedangkan alihragam DCT yang digunakan adalah operasi blok 4x4, yang diharapkan dapat mengurangi beban komputasi. Berdasarkan pengujian yang dilakukan terhadap algoritma watermarking, menunjukkan bahwa kedua algoritma watermarking yang dikembangkan secara umum tahan terhadap pemberian derau, operasi geometris citra dan operasi-operasi pengolahan citra. Algoritma watermarking yang dikembangkan kurang dapat bertahan terhadap serangan-serangan tapis lolos-bawah dan tapis median. Kedua algoritma watermarking yang dikembangkan mempunyai unjuk kerja yang sangat baik terhadap serangan tapis lolos-atas.in_ID
