Provenance
Definition
The documented origin of a media file: the device that captured it, the time and location of capture, the chain of custody from capture to court. Authentication examinations assess provenance by analysing file structure, metadata, sensor fingerprints, and encoding parameters.
- Key forensic uses
- Plant material, pollen, sediment, soil, ceramics, and geological minerals
- Primary analysis method
- Matching sample assemblages to reference data from known geographic locations or characteristic habitats
- Related concept in geology
- Heavy-mineral suites reflect the source rock type and are used to trace sediment to its original geological source area
Common questions
What does provenance mean in forensics?+
Provenance is the geographic origin or source of a piece of evidence. Forensic experts use it to trace where a plant sample, soil, ceramic, or other material came from. This can link evidence to a person, suspect, or location of interest.
How is provenance determined from botanical evidence?+
Plant material like pollen carries a signature of its habitat and origin. Experts compare the plant assemblage found on a suspect or at a scene to reference samples from known locations. A match suggests where the material came from.
Is provenance the same as where something was made?+
No. In ceramics and pottery, provenance refers to where the raw materials were sourced, while the production place is where the object was actually made. These often coincide, but they can differ if clay was traded before manufacture.
