Digital Forensics

AI Content Authentication

When the evidence might be AI-generated, you need forensic proof.

AI content authentication is the forensic analysis of digital media to determine whether it was created or altered by artificial intelligence. Sherlock Forensics provides deepfake detection, AI document authentication and synthetic media forensics for legal proceedings. Our examiners have provided court testimony on AI-generated evidence and digital media provenance.

Generative AI has made it trivial to fabricate images, video, audio and documents that pass casual inspection. When synthetic media enters a legal proceeding, insurance claim or corporate investigation, forensic authentication is the only reliable method to separate real from generated.

Authentication Services

01 - Deepfake

Deepfake Detection for Legal Proceedings

Forensic analysis of video and image evidence suspected of AI generation or manipulation. We examine GAN artifacts, temporal inconsistencies, lighting anomalies and compression signatures. Our findings are documented to evidentiary standards and presented with chain-of-custody documentation suitable for court submission.

02 - Documents

AI Document Authentication

Verification of documents suspected of AI generation. We analyze linguistic patterns, metadata provenance, formatting artifacts and content consistency to determine whether contracts, emails, reports or other documents were produced by large language models. Critical for fraud investigations and contract disputes.

03 - Audio

Voice Clone and Audio Forensics

Detection of AI-generated voice recordings and audio manipulation. We examine spectral characteristics, breathing patterns, prosody markers and encoding metadata to identify synthetic speech. Used in cases involving fabricated confessions, fraudulent voice authorization and impersonation.

04 - Expert

Expert Witness Testimony

Court-qualified testimony on AI content authenticity. Ryan and our forensic team have provided expert witness testimony in proceedings involving digital evidence authentication. We explain complex forensic findings in clear language that judges and juries can evaluate. Our testimony covers methodology, confidence levels and limitations.

05 - Provenance

Digital Provenance Analysis

End-to-end provenance chain verification for digital media. We trace content origin through metadata examination, C2PA content credential verification, EXIF analysis and platform-specific artifact review. Establishes when and where digital content was created and whether it has been modified.

06 - Corporate

Corporate Investigation Support

AI content authentication for internal investigations, HR disputes and insurance claims. We determine whether submitted evidence is authentic, modified or entirely AI-generated. Deliverables include detailed forensic reports with reproducible methodology and clear conclusions.

Methodology

Detection Techniques

Technique Media Type What It Detects
GAN Artifact Analysis Image, Video Spectral fingerprints left by generative models
Temporal Consistency Video Frame-to-frame anomalies in face-swapped video
Metadata Provenance All Missing or inconsistent creation metadata
Linguistic Analysis Text, Documents LLM-characteristic patterns and perplexity
Spectral Analysis Audio Synthetic speech markers and voice cloning artifacts

Frequently Asked Questions

AI Authentication FAQs

What is AI content authentication?
The forensic process of determining whether digital media was created or manipulated by artificial intelligence. Uses metadata analysis, artifact detection and provenance verification to establish authenticity for legal proceedings.
Can deepfake evidence be challenged in court?
Yes. A qualified expert witness can testify to AI generation artifacts, metadata inconsistencies and provenance failures that establish media as synthetic. Our team has provided court testimony on AI-generated evidence authentication in British Columbia.
How accurate is deepfake detection?
Layered forensic analysis combining multiple detection techniques provides high-confidence results suitable for legal proceedings. No single technique is definitive, which is why we use a multi-method approach documented with reproducible methodology.
