DSi’s forensic analyst examined audio files from a spy pen to determine key data had been altered.
When discovery was produced in an acquisitions case, attorneys found three audio recordings of a meeting that they did not know was being recorded. Plus, there were anomalies in the metadata properties of the audio files.
DSi’s forensic analyst proved the files were created by a spy pen and then altered by:
- Analyzing the metadata, especially the date created field
- Looking at the raw binary content of the files in forensic software
- Ordering the same brand of spy pen to compare file types
- Analyzing the original spy pen used in the meeting
Learn how DSi was able to use a variety of forensic methods to prove that the audio files produced were not original.
