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.
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.
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.
