Abstract :

Reliable evidence requires proper handling and factual consistency. A process inclusive of hash tags, metadata and content analysis. A hash tag ensures that everyone is working from the same set of data. Data analysis can detect if a file was altered prior to receipt. Metadata provides a cross reference of a file?s expected structure, GPS coordinates, time and recording configuration. File tampering can be detected by comparing hash tag, data, metadata and relevant external data. This session will detail basic tools and methods to differentiate an original from its duplicate or an altered copy. Historical examples and emerging technologies will be included.
