Providing Security for E-Government Document Images Using Digital Watermarking in the Frequency Domain

Many countries around the world have realized the benefits of the e-government platform in peoples' daily life, and accordingly have already made partial implementations of the key e-government processes. However, before full implementation of all potential services can be made, governments demand the deployment of effective information security measures to ensure secrecy and privacy of their citizens. In this paper, a robust watermarking algorithm is proposed to provide copyright protection for e-government document images. The proposed algorithm utilizes two transforms: the Discrete Wavelet Transformation (DWT) and the Singular Value Decomposition (SVD). Experimental results demonstrate that the proposed e-government document images watermarking algorithm performs considerably well compared to existing relevant algorithms.
