Securing the Digital Documents for Application in E-Governance

Abstract

Information security is essential to an effective and safe e-government. The objective of e-governments is to provide services accessible to an entire region at a reasonable cost and in a reasonable amount of time. Government offices can use information technology and the Internet to provide better services to people and businesses and to facilitate cooperation among government institutions. However, e-governments must ensure efficient information authentication. Watermarking, or data hiding, can help e-governments meet these goals. In this work, we will propose a robust and secure watermark technology and try to make the optimal balance between the major benchmark imperceptibility, robustness and capacity. When digital watermarks are used for intellectual property protection, many e-governance and e-commerce applications are beneficial and they include the online and offline distribution of multimedia content, broadcast services, document verification, and ownership identification and so on. The result of present study also confirmed that there are numerous emerging tools that rectify the drawback of one and another. The objective of the study of various experimentalists remains the same that is to prevent the digital media from being comprised. One level DWT is applied on both the cover image and the watermark image. The KL transform is applied on the LH band of the cover image. The watermarked image is denoised using the KSVD process with improved PSNR. The possible solution to optimize the major benchmark performance parameters are hybrid approach, watermarking with encryption, watermarking with ECCs, watermarking with genetic algorithm. The watermarked image is checked on the attack of poisson noise but the PSNR drop is expectable in positive range. Chapter wise description of the thesis report is describe as follows:
