To address this challenge, investigators typically apply cryptographic hash functions to identify known files. However, cryptographic hashing only allows the detection of files that exactly match the known file hash values or fingerprints. This paper demonstrates the benefits of using approximate matching to locate relevant files. The experiments described in this paper used three test images of Windows XP, Windows 7 and Ubuntu 12.04 systems to evaluate fingerprint-based comparisons. The results reveal that approximate matching can improve file identification – in one case, increasing the identification rate from 1.82% to 23.76%. %G English %Z TC 11 %Z WG 11.9 %2 https://inria.hal.science/hal-01393769/document %2 https://inria.hal.science/hal-01393769/file/978-3-662-44952-3_11_Chapter.pdf %L hal-01393769 %U https://inria.hal.science/hal-01393769 %~ IFIP-LNCS %~ IFIP %~ IFIP-AICT %~ IFIP-TC %~ IFIP-WG %~ IFIP-TC11 %~ IFIP-DF %~ IFIP-WG11-9 %~ IFIP-AICT-433
