Forensic Analysis of Database Tampering
by Kyriacos E. Pavlou, Richard T. Snodgrass
Publisher: University of Arizona 2008
Number of pages: 71
Description:
This paper shows how to determine when the tampering occurred, what data was tampered, and thus perhaps ultimately who did the tampering, via forensic analysis. We present four successively more sophisticated forensic analysis algorithms: the Monochromatic, RGBY, Tiled Bitmap, and a3D Algorithms, and characterize their "forensic cost" under worst-case, best-case, and average case assumptions on the distribution of corruption sites.
