This paper considers the problem of non-intrusive forensic analysis of the individual components in visual sensors and its implementation. As a new addition to the emerging area of forensic engineering, we present a framework for analyzing technologies employed inside digital cameras based on output images, and develop a set of forensic signal processing algorithms for visual sensors based on color array sensor and interpolation methods. We show through simulations that the proposed method isdoi:10.1109/icassp.2006.1661297 dblp:conf/icassp/Swaminathan0L06 fatcat:o37xwe2cojfgxgqtuhrb26blcm
