Expert Opinion Review & Digital Evidence Integrity Assessment

A digital forensics expert report can determine the outcome of a legal case.
This is why it must be methodologically sound, technically correct,
and fully compliant with chain‑of‑custody and evidence integrity principles.

I provide an independent, objective review that establishes:

• whether the expert report has real evidential value,
• whether the analysis was conducted correctly and reliably,
• whether the report contains technical or logical errors,
• whether data integrity and proper evidence handling were maintained,
• what cannot be concluded from the submitted materials,
• whether the expert’s conclusions follow logically from the evidence.

What exactly do I verify?

✔ 1. Methodology & Data Acquisition

• correctness of forensic imaging (bit‑by‑bit / device image),
• compliance with DFIR (Digital Forensics & Incident Response) standards,
• tools used during analysis and their limitations.

✔ 2. Chain‑of‑Custody Verification

• evidence handling and documentation,
• absence of unauthorised modifications,
• integrity of the original source media,
• proper logging of every acquisition and analysis step.

✔ 3. Technical & Logical Accuracy

• logical contradictions,
• missing analytical steps,
• mixing facts with interpretations,
• conclusions unsupported by data.

✔ 4. Evidential Value Assessment

• which parts of the opinion are admissible or useful in court,
• which parts lack evidential value,
• what can be established from digital evidence — and what cannot.

✔ 5. Review or Supplementary Opinion

Upon request, I prepare a full review opinion
that may be submitted directly into the case file.

How the process works

1. Initial assessment (48h)
   You receive an early indication of potential issues
   and whether a full analysis is justified.

2. Full technical examination
   Review of the expert report, logs, images, acquisition documentation.

3. Report / Review Opinion
   Clear findings: what is correct, what is flawed, and why.

4. Procedural support
   Consultation with legal counsel, expert questions, preparation for hearings.
