Interpret digital document traces with appropriate caution
A file property timestamp is not necessarily the genuine creation date of a document.
Metadata is not the same as authenticity
Office files, PDFs and images may contain technical properties: editing software, stored dates, dimensions and sometimes processing history. These details help explain a document’s lifecycle, flag inconsistencies and improve internal procedures. They can also change during conversion, transfer or routine re-export.
Metadata is an observation within a particular technical context. It rarely proves who actually authored a document or that nothing changed. Important files should be assessed alongside delivery channels, available signatures, preserved versions and production context. A valid electronic signature may provide specific assurances, but these depend on the signature scheme and verification performed.
Practical checkpoints
- Preserve a reference copy before analysis.
- Record the software and method used to inspect the file.
- Compare technical indicators with delivery context.
- Do not attribute authorship using metadata alone.
Discuss a technical or training requirement
Describe your technical environment, documentation question or prevention needs. The scope of any service is agreed in advance.

Work from a copy where possible and avoid modifying the original. A cryptographic hash can help demonstrate that a copy matches the chosen reference file; it cannot prove that the reference was authentic before collection. That distinction matters in technical reports and when training staff who receive sensitive digital documents.
This guide concerns technical analysis, prevention and documentation. Third-party systems require an authorised scope; Pacta does not offer named-person private investigations.
