The environment using multimedia information such as image, audio, and video is widely applied through the rapid development of the IT environment. The digital content industry applying this has been developed in a variety of forms. However, copyright is subjected to a serious threat as digital content is distributed in quantity with the spread of the Internet. Also, business model of companies is threatened largely by the variety of attacks such as illegal copy and transformation of digital content. In this paper, we propose a hybrid encryption in order to prevent copyright information damage by malicious attacks. The encryption process in two steps is performed in order to enhance hiding copyright in the proposed technique. The block encryption process is performs to prevent exposure and transformation of encrypted information after encryption performs using ARIA algorithm for copyright information. The encrypted copyright information like this improved robustness to several of attacks. The performance of the proposed technique is confirmed by experiments.
