TERA Signature extends TrustPDF upstream into document preparation and multi-party signing. One controlled document can move across locations without the print, sign, scan, and forward cycle. TrustPDF remains the verification and forensic layer.
Prepare a controlled document, add partners, choose parallel or sequential signing, review before release, collect signatures, show elapsed signing time, and preserve portable evidence.
TrustPDF remains the security side of the platform. It verifies document integrity and can host configured forensic and connected assurance capabilities after the signing workflow is complete.
A research group, review team, or business partnership can sign one controlled version in parallel across geographic locations instead of repeatedly printing, scanning, and forwarding new copies.
Core signing does not require AI. Human intent, document integrity, access verification, timing, review, release, and evidence remain functional without AI. Optional AI may assist understanding but cannot sign or release for a person.
TrustPDF Security provides a governed document-integrity layer for important workflows. The deployable TERA Signature path records controlled PDF fingerprints, signing intent, partner access events, timestamps, and completion evidence. TrustPDF can verify that evidence and host additional forensic capabilities as they are validated and configured.
The platform is designed for organizations that need clear document provenance and accountable review. Current deployment focuses on SHA-256 integrity, multi-party signing evidence, shared workflow state, server-sealed evidence, and transparent assurance boundaries. Additional integrations and regulated-industry controls should be enabled only after their deployment requirements are validated.
For research teams, publishers, professional groups, and organizations that need distributed signing with document review, visible timing, and verifiable evidence.
