Encoding forensic multimedia evidence from MARF applications as Forensic Lucid expressions

Abstract

In this work we summarize biometric evidence as well as file type evidence extraction "exported" as formal Forensic Lucid language expression in the form of higher-order intensional contexts for further case analysis by a system that interprets Forensic Lucid expressions for claim verification and event reconstruction. The digital evidence is exported from the Modular Audio Recognition Framework (MARF)'s applications runs on a set of data comprising biometric voice recordings for speaker, gender, spoken accent, etc. as well as more general file type analysis using signal and pattern recognition processing techniques. The focus is in translation aspect of the extracted evidence into formal Forensic Lucid expressions for further analysis. © 2010 Springer Science+Business Media B.V.
