Abstract

Recently the need for “digital evidence bags” – a common storage format for digital evidence – has been identified as a key requirement for enabling inter-organisational sharing of digital evidence, and interoperability between forensic analysis tools. Recent work has described an ontology based approach to correlation of event log based evidence, using semantic web technologies for describing and representing event log based digital evidence. In this paper we apply the representational approach to the integration of metadata related to digital evidence, and propose a globally unique identification scheme for digital evidence and related metadata. We relate the representational approach to the digital evidence bags concept identifying a number of shortcomings. We propose an alternative architecture for digital evidence bags, which we call the sealed digital evidence bags architecture. This approach treats bags as immutable objects, and facilitates the building of a corpus of digital evidence by composition and referencing between evidence bags. This architecture facilitates modular forensic tool development and interoperability between forensics tools.

Impact and interest:

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
