ABSTRAKSI: Watermarking merupakan salah satu cara perlindungan hak cipta pada konten multimedia khusunya video yang biasa sering disebut video watermarking. Banyak metode yang dapat digunakan dan salah satunya adalah video watermarking pada temporal difference. Metode ini menggunakan Discrete Wavelet Transform yang selanjutnya dilakukan penyisipan bit stream watermark ke dalam koefisien wavelet. Proses penyisipan koefisien ini hanya dilakukan pada sebagian blok yang diangap sebagai motion region. Hal ini dimaksudkan agar keberadaan penyisipan watermark sulit terdeteksi dan menyebar dibeberapa frame. Mencoba menguji ketahanan metode video watermarking ini dengan melakukan pengubahan beberapa parameter yang dianggap penting agar tahan dari serangan geometri seperti noise salt & pepper, gaussian filter, frame dropping dan Cropping. Metode temporal difference ini tergolong tahan dari serangan geometri asalkan inisiasi nilai parameter yang tepat dan urutan dari bit stream tetap terjaga.Kata Kunci : DWT, Motion Region, Temporal Difference, Bit StreamABSTRACT: Watermarking is one way of copyright protection of multimedia content especially in video which is called video watermarking. Many methods can be used to watermark a video and one of them is video watermarking on temporal difference. This method uses the Discrete Wavelet Transform is then performed bit stream watermark embedding into wavelet coefficients. The process of insertion of this coefficient is only performed on partially blocks the motion considered as a region. This is so difficult to detect the presence of the watermark embedding and spread in several frames. Trying to test the resilience of a video watermarking method is to perform the conversion of some parameters that are considered important for durability of geometry attacks such as salt & pepper noise, gaussian filter, frame dropping and Cropping. Temporal difference method is relatively resistant to attack as long as the geometry of the initiation of appropriate parameter values and the order of the bit stream is maintained.Keyword: DWT, Motion Region, Temporal Difference, Bit Stream
