AI-Generated Evidence in Litigation: Authentication and Admissibility Considerations

Online Defamation Investigations for Attorneys: From Anonymous Account to Identifiable Defendant
When an online defamation matter reaches an attorney, one of the first questions is often deceptively simple: Who is actually behind it?

Deepfake Investigation: Voice Cloning and Identity Abuse
Deepfake investigation work increasingly involves cloned voices and synthetic video appearing as disputed evidence in employment, family and fraud matters. Rexxfield combines provenance analysis, chain-of-custody review and independent corroboration, because a detector score alone is never enough to prove what a file really is.

The Rise of AI-Powered Harassment Campaigns
AI harassment campaigns can make a single operator look like dozens of independent attackers, using generated personas, biographies and messages at scale. Rexxfield investigates the technical and behavioral fingerprints that separate genuine coordination from one person hiding behind many accounts.
