The thesis by James Migletz, titled 'Automated Metadata Extraction,' presents a novel technique for batch processing disk images to automatically extract metadata from various file types. The core of this technique is the program 'fiwalk,' which features a plug-in architecture allowing for the integration of new metadata extractors. The thesis discusses the significance of metadata in computer forensics, detailing how it can provide crucial information about files, such as creation and modification dates, authorship, and more. It includes an examination of common file formats like Microsoft Office documents and JPEG images, highlighting the metadata extraction capabilities through specific plug-ins developed during the research. The findings indicate that while document files contain rich metadata useful for forensic investigations, media files offer less pertinent information. The work also identifies deficiencies in existing extraction tools and suggests areas for future enhancement.
