Abstract

Kemudahan penyebaran citra digital melalui internet memiliki sisi positif dan negatif terutama bagi pemilik asli citra digital tersebut. Sisi positif dari kemudahan penyebaran adalah dengan cepatnya pemilik citra tersebut menyebarkan file citra digital ke berbagai alamat situs di dunia. Sedangkan sisi negatifnya adalah jika tidak ada hak cipta yang berfungsi sebagai pelindung citra yang disebarkan tersebut, maka citra digital ini, yang misalkan adalah hasil foto komersil, atau hasil karya lukisan digital, akan sangat mudah diakui kepemelikannya oleh pihak lain. Watermark merupakan salah satu solusi untuk melindungi hak cipta terhadap foto digital yang dihasilkan. Dengan diterapkannya Digital Image Watermarking ini maka hak cipta foto digital yang dihasilkan akan terlindungi dengan cara menyisipkan informasi tambahan seperti informasi pemilik, keaslian, dsb ke dalam foto digital tersebut. Discrete Wavelet Transform (DWT) merupakan salah satu kakas yang banyak digunakan dalam teknik watermarking dalam domain transform. ================================================================================================================== Ease of deployment of digital imagery through the internet has positive and negative sides, especially for owners of the original image. The positive side of the ease is the owner of that image can deploy digital image files to various sites address in the world. While the downside is that if there is no copyright that uses as protector of the transmitted image, the ownership of the digital image, such as a commercial photograph, or works of digital paintings, will be very easily claimed by other parties. Watermark is one solution to protect the copyright of the digital photo produced. With the implementation of the Digital Image Watermarking, the copyright of digital photos produced will be protected by inserting additional information such as owner information, authenticity, etc. into the digital photo. Discrete Wavelet Transform (DWT) is one option which is widely used in watermarking techniques in the domain transform.
