Scientific Investigation

Digital Forensics & Technical Evidence Analysis

We provide specialised digital forensics and technical investigation services for legal, corporate, insurance, and investigative clients. Our practice combines advanced signal processing, machine learning, and reproducible scientific methodologies to analyze multimedia, vehicle telemetry, and digital evidence.

Services

Areas of Forensic Analysis

Rigorous, reproducible analysis across four specialized technical investigation domains.

Image & Video Forensics

Verifying the integrity, source, and history of digital visual evidence. We conduct frame-level authenticity analysis, detect tampering or splicing, and evaluate compression artifacts.

  • Tampering, cloning, and insertion detection
  • Frame-rate, GOP structure, and re-encoding artifact analysis
  • Source device attribution and metadata verification

Audio Forensics & Spectral Analysis

Examining sound recordings for continuity, background environment consistency, and tampering. We apply advanced spectral analysis to investigate edits and enhance speech intelligibility.

  • Acoustic background continuity and edit boundary detection
  • FFT spectral analysis and frequency anomaly detection
  • Noise reduction and speech clarity enhancement

Vehicle Event Data Recorder (EDR) Analysis

Extracting and analyzing critical telemetry from vehicle airbag control modules and Event Data Recorders following collisions. We reconstruct dynamic pre-crash and crash phase parameters.

  • Pre-crash vehicle speed, throttle position, and engine RPM
  • Braking status, ABS activity, and steering angle inputs
  • Delta-V force curves and seatbelt restraint deployment

Signature Recognition & Document Analysis

Technical evaluation of signatures and digital documents to assess authenticity. We examine stroke geometry, pressure dynamics, line continuity, and digital document metadata.

  • Morphological stroke comparison against genuine reference samples
  • Digital document structure and metadata revision history
  • Discontinuity and tremor analysis in contested signatures

Forensic Research & Technology Partnership

In complex multimedia forensic investigations and algorithm-assisted verification, VAI SciTech collaborates with specialised technical partners including ICTLab S.r.l., combining scientific depth with verified analytical methodologies.

ICTLab S.r.l.
Methodology

Forensic Integrity & Objective Reporting

Our investigations are conducted under strict scientific protocols to guarantee reproducibility and auditability.

Chain of Custody & Preservation

Bit-stream forensic copies and cryptographic hashing (SHA-256) are produced immediately upon receipt. Original media remains unaltered.

Reproducible Analysis

All examination steps, calibration parameters, and algorithms used are documented in detail so that other technical experts can reproduce results.

Clear Technical Reporting

We deliver structured technical reports presenting objective observations, methodology, findings, and technical conclusions without speculation.

Professional Scope & Impartiality: VAI SciTech provides objective scientific analysis and technical evidence evaluation. We act as technical specialists; we do not provide legal counsel or guarantee specific judicial outcomes. All findings are derived through transparent, verifiable scientific procedures.
