Secure Your Transactions with Qwantum Signature Authentication™
A next-generation electronic signature capture system by MagTek, Qwantum Signature Authentication transforms handwritten input into secure, verifiable digital artifacts. Captured via trusted hardware (DynaFlex II PED) and bundled with rich contextual metadata, each signature delivers unmatched authenticity, auditability, and portability, ideal for industries demanding high integrity and regulatory compliance.
Key Differentiators
Beyond the Signature: A Framework of Trust
Hardware-Backed Trust
All signatures are captured on a DynaFlex II PED (PCI PTS 6.x PED), ensuring tamper-resistant and genuine user input.
AES-256 Encryption with CMAC + DUKPT
Each signature is encrypted using a unique session key and authenticated with a separate CMAC key to guarantee privacy and integrity.
Context-Rich Metadata
Captures who signed, when, where, and on what device, transforming the signature into a verifiable digital record.
Provenance Without Blockchain
Provides NFT-like traceability without relying on distributed ledgers. All data is portable, verifiable, and encrypted.
Future-Ready Architecture
Supports multi-signer workflows, document linking, role sequencing, and verification via QR codes, NFC tokens, or apps.
Core Concept and Workflow
A multi-layered approach to security, from capture to storage.
1. Secure Capture
Signatures are captured as raw 320x240 pixel grayscale images on a DynaFlex II PED, ensuring a high-fidelity record at the point of interaction.
2. Data Encryption
Each signature is encrypted with a unique AES-256 key (derived via DUKPT) and validated with a CMAC to ensure confidentiality and integrity.
3. Contextualization
Contextual metadata is embedded alongside the signature. The entire payload is treated as an opaque, encrypted binary block for maximum flexibility and security.
