THE DIGITAL EVIDENCE JOURNAL
Can altered PDFs be detected?
Often, yes. Examination may reveal altered text, inconsistent metadata, missing content or traces of editing.
What should I do first?
Preserve the original file, avoid editing it, record where it came from and seek forensic advice promptly.
What can forensic examination prove?
It can assess authenticity, identify manipulation and explain findings clearly, but conclusions depend on available evidence.
Can metadata reveal document history?
Potentially. Metadata, file structure, timestamps and source information may help establish when and how evidence changed.
Can findings support legal proceedings?
Yes. A forensic report can present methods, findings and limitations in a form suitable for legal or business decisions.
