HandAuth Pro

HandAuth Pro is a preliminary, AI-based screening tool for handwritten signatures and handwriting samples, built to support legal experts and attorneys ahead of certified forensic document examination. It assists in handwriting comparison for court cases, forensic examination reports, and disputed document matters, helping legal teams prioritize which cases warrant a full expert review before engaging a certified specialist.

Key Features & Functions:

Legal Case Preparation Support
Assists lawyers and legal professionals in preparing materials for court cases, forensic examination reports, and disputed document matters, and helps prioritize which cases warrant certified forensic review.

Preliminary Probability Estimate
Generates an orientational probability score indicating whether a signature shows early warning signs. The score is intended as a triage indicator rather than a definitive determination of authenticity.

Non-Handwritten Artifact Detection
Screens for indicators that a signature may not have been produced by hand, including printed text, screen captures, and signs of synthetic generation.

Multiple Reference Signature Comparison
Supports upload of several reference signatures for a single comparison, intended to improve accuracy and reduce false positives during preliminary triage.

Stroke, Letter Formation, and Spacing Analysis
Analyzes stroke structure, continuity and directionality, letter and character formation, and inter-letter/inter-word spacing and proportions to identify deviations between compared samples.

Signature Pattern Comparison
Compares structural patterns and pen-movement sequences across multiple signature samples to assess consistency or identify deviations.

Visual Summary Reporting
Produces a structured report with visual indicators summarizing comparison results, intended for internal review rather than as a standalone expert finding.

Local Processing
Processes submitted files without transmitting or storing them on external servers; deployment in secure or air-gapped environments is available on request.

Enterprise API Integration
Offers API integration for enterprise systems, including document management platforms and CRM environments, for organizations with sufficient volume and use case.
