[e-BIO.DocSign] & [e-BIO.Verify] — Next-Generation Electronic Signature & Document Authentication by [e-Security.BIO]

[e-Security.BIO] is a Portuguese deep-tech startup developing next-generation digital trust solutions for organizations that require legally binding, tamper-resistant, and verifiable document workflows. Our two flagship products — [e-BIO.DocSign] and [e-BIO.Verify] — form a complete end-to-end ecosystem for electronic signing and document authentication.

**[e-BIO.DocSign] — Electronic Signature, Reinvented

[e-BIO.DocSign]** is a proprietary electronic signature solution designed to operate in two modes:
• Standalone mode: functions independently as an autonomous electronic signature solution, supported by AI-powered biometric identity verification (including liveness detection and facial recognition) and blockchain-anchored audit trails.
• Hybrid / integrated mode: complements and enhances existing signature infrastructures such as Chave Móvel Digital (CMD), X.509 digital certificates, PKI-based solutions, and other traditional electronic signature methods, adding an extra biometric and blockchain-based layer of trust to current workflows.

**Key Features of [e-BIO.DocSign]:
**• Qualified Electronic Signature (QES) designed for alignment with **eIDAS 2.0
**• AI-powered biometric identity binding at the moment of signature
• Blockchain-anchored signature records with immutable timestamps and audit trails
• REST API compatibility with enterprise document management and workflow systems
• Support across web, mobile (iOS/Android), and desktop environments

**[e-BIO.Verify] — Trust Beyond the Screen

[e-BIO.Verify]** is the verification counterpart to [e-BIO.DocSign], enabling any party to validate the authenticity and integrity of a signed document instantly, regardless of format.

It supports two verification modes:
• Digital verification: validates the cryptographic signature, blockchain proof, and biometric binding of documents signed with [e-BIO.DocSign] in real time.
• Physical / printed document verification: using QR codes or embedded visual authentication markers, [e-BIO.Verify] can authenticate printed documents, ensuring that a physical copy of a digitally signed document remains verifiable.

This dual verification capability makes [e-BIO.Verify] especially valuable in sectors where documents move between digital workflows and physical handling, such as notarial services, legal contracts, public administration records, healthcare documentation, and financial agreements.

**Who It Is For

**• Government and Public Administration: modernize document workflows with legally binding and auditable digital signatures aligned with EU regulatory requirements.
• Legal and Notarial Professionals: issue and verify signed documents with strong legal standing across both digital and physical formats.
• Financial Services: onboard clients and execute contracts with enhanced biometric identity assurance.
• Healthcare: sign and verify clinical records, informed consent forms, and patient documentation with confidence.
• Enterprises: integrate [e-BIO.DocSign] into existing ERP, DMS, and workflow platforms through APIs.

**Why [e-Security.BIO]
**• Built with eIDAS 2.0 and GDPR readiness in mind
• Unique capability for **both digital and physical document verification
**• Biometric + blockchain dual-layer trust architecture
• Interoperable with existing signature infrastructures, with **no forced migration
**• Portugal-based team with 20+ years of experience in software architecture, cybersecurity, and digital identity
