Origin and version
The analysis identifies the supplied copy, declared origin, versions and any conversions or sharing steps that may affect the material.
Documents and integrity
Digital document examination with documented scope, origin and transformations.
A digital document must be examined according to its origin, available version, transmission path and transformations, rather than by its appearance alone.
Technical elements
Structure, metadata, rendering, signatures, identifiers and consistency between available records can be examined according to scope.
Limits
A copy, screenshot or incomplete file may limit observations. The conclusion remains proportional to the material and procedure available.
