Abstract

Digital image archival and distribution systems are an indispensable part of the modern digital age. Organizations perceive a need for increased information security. However, conventional image encryption methods are not versatile enough to meet more advanced image security demands. We propose a universal multi-level ROI image encryption architecture that is based on biometric data. The proposed architecture ensures that different users can only view certain parts of an image based on their level of authority. Biometric authentication is used to ensure that only an authorized individual can view the encrypted image content. The architecture is designed such that it can be applied to any existing raster image format while maintaining full backwards compatibility so that images can be viewed using popular image viewers. Experimental results demonstrate the effectiveness of this architecture in providing conditional content access
