A Case Based Reasoning Framework for Improving the Trustworthiness of Digital Forensic Investigations

A novel concept for improving the trustworthiness of results obtained from digital investigations is presented. Case Based Reasoning Forensic Auditor (CBR-FA) is a method by which results from previous digital forensic examinations are stored and reused to audit current digital forensic investigations. CBR-FA provides a method for evaluating digital forensic investigations in order to provide a practitioner with a level of reassurance that evidence that is relevant to their case has not been missed. The structure of CBR-FA is discussed as are the methodologies it incorporates as part of its auditing functionality.
