In this paper, we propose a novel model for 3D object watermarking. The proposed method is based on the properties of the discrete cosine transform (DCT) of the 3D object vertices to embed a secret grayscale image three times. The watermarking process takes place by using the vertices coefficients and the encrypted image pixels. Moreover, the extraction process is totally blind based on the reverse steps of the embedding process to recover the secret grayscale image. Various performance aspects of the method are measured and compared between the original 3D object and the watermarked one using Euclidean distance, Manhattan distance, cosine distance, and correlation distance. The obtained results show that the proposed model provides better performances in terms of execution time and invisibility.

The increasing amount of research on watermarking over the past decade has been largely driven by its important applications in digital copyrights management and protection. Digital watermarking is the act of hiding a message related to a digital signal (i.e. an image, song, video) within the signal itself. It is a concept closely related to steganography, in that they both hide a message inside a digital signal. However, what separates them is their goal. Watermarking tries to hide a message related to the actual content of the digital signal, while in steganography the digital signal has no relation to the message, and it is merely used as a cover to hide its existence. With the emerging of low cost 3D display devices, different kinds of 3D applications and the amount of 3D content are booming up, recently. Effective digital watermarking systems for 3D content protection will play an important role for developing and promoting the 3D entertainment industry. The proposed 3D watermarking technique employs the method of slice extraction from a 3D volume. An obj file is used and the wave front object data is obtained.DWT technique is used to embed the secret binary data into one of the extracted slices. The inverse operation is performed at the receiver using the same secret key used at the transmitter. Finally, the watermark is extracted and the quality measures of the reconstructed image is calculated.

Bu çalışmada, internet ortamından görsel veriler edinilirken telif hakkı konusunun yeri ve önemi araştırılmıştır. Örneklem evreni Artvin Çoruh Üniversitesi olarak belirlenmiş olup; veriler üniversite öğrencilerinden basit tesadüfi örnekleme yöntemi ile temin edilmiştir. Öğrencilere bilgisayar ortamında Google Form uygulaması aracılığıyla çevrimiçi anket ölçeği hazırlanarak çalışma başlığına uygun sorular sorulmuştur. Sorular öğrencilerin, internet ortamında sanatsal film, dizi veya herhangi bir hareketli görsel seçiminde nasıl bir yol izlediklerini, izledikleri yolları seçerken hangi faktörlerin etkili olduğunu ve telif hakkı hassasiyeti konusu üzerine haberdarlığını ve duyarlılığını ölçmeye yönelik olmuştur. Anket sonuçları SPSS programı aracılığıyla analiz edilip rapor hazırlanmıştır.
