HandAuth Pro

HandAuth Pro is an API-based signature verification and screening solution designed to support legal professionals, forensic document examiners, and organizations handling document authentication at scale.

Key Features & Functions:

Reference Signature Comparison
Compares a submitted handwritten signature or handwriting sample against one or more reference samples, analyzing stroke structure, continuity, letter formation, spacing, and proportions to identify structural inconsistencies between compared samples.

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, supporting fraud-detection use cases alongside authenticity screening.

Probability Score and Structured Reporting
Generates an orientational probability score along with a structured visual report intended to support internal triage and case-prioritization workflows.

Preliminary Screening Scope
Results are intended as a preliminary screening tool, not a certified forensic opinion, expert witness testimony, or court-admissible evidence; legal teams are advised to engage a qualified forensic document examiner for legally binding determinations.

API-First Integration
Designed for integration into existing legal, case management, document management, and enterprise systems rather than delivered as a standalone application.

On-Premise and Air-Gapped Deployment
Available for organizations with strict data-residency or security requirements.

Digital Signature Validation
For workflows involving electronically signed PDFs, performs digital signature validation, including certificate chain validation, OCSP/CRL revocation checking, and PAdES conformance level detection.

Cross-Industry Fraud Screening
Beyond legal use, applied by banks, notaries, insurance companies, and investigators for document-based fraud screening and verification workflows.
