Abstract
Digitalni vodeni žigovi služe za zaštitu multimedijskih dokumenata na Internetu. Postoje razne vrste digitalnih vodenih žigova i tehnike ubacivanja istih. U cilju ispitivanja tehnike diskretne Hadamardove transformacije ostvaren je sustav digitalnih vodenih žigova. Unutar sustava su ostvareni proces ubacivanja, izlučivanja i verifikacije žiga. Provedeni su napadi rezanja, rotacije, zamućivanja, izoštravanja, skaliranja i kompresije kako bi se ustanovile slabosti sustava. Sustav je pokazao robusnost protiv navedenih napada.
Abstract (english)
Digital watermarks are used for protection of multimedia on Internet. There are different types of digital watermarks and embedding processes. For the purpose of testing of discrete Hadamard transform, a complete process of digital watermarking using DHT is created. The process includes insertion, extraction and verification of watermark. Attacks such as cropping, rotation, adding a blur, scaling, sharpening and JPEG compression are applied to detect weaknesses of watermarking process. Watermarking process showed robustness against attacks.
