Digital Forensics: Electronic Evidence Collection, Examination and Analysis by Using Combine Moments in Spatial and Transform Domain

摘要

A novel digital forensics tool is developed by combining wavelet invariant with spatial moments. A forensic printed circuit board image matching system is presented that is capable of probing a large database of digital images of circuit boards and compare them for similarity to provide investigation leads for electronic crimes digital forensic science investigations. The developed system has been implemented, and proved to be very efficient in detection similarities between a target image and a large image database even when the target image is noisy, scaled or mirrored.
