The increasing globalization led to the transmission of vast amount of digital documents like texts, images, videos or audios over the internet from one point to another. However, some of these documents might be highly confidential and its transmission over the internet must be protected from unauthorized access. In this paper, the authors have proposed a novel hybrid Arnold transform scheme based on dual tree complex wavelet transform with block shuffling internally as well as externally. In this paper, they have provided double layer of security by utilizing the multi-resolution property of wavelet using Arnold transform and block shuffling.
