dLoc™ System

The next generation document authentication for vital records


Linxens dLoc™ document authentication solution allows any vital records issuing agency to turn their offline documents into digital instances that can be easily connected to existing digital systems.

To achieve this, the dLoc™ solution uses three key components: Linxens NFC dLoc™ seals which easily attach to existing documents, the client customizable dLoc mobile app, and a cloud based engine running alongside either a public or private blockchain.

Linxens dLoc™ can be easily integrated into any existing certificate or document so the original does not need to be altered in any way. The impact on well-rehearsed processes is negligible, allowing for seamless integration of Linxens dLoc™ into incumbent systems and existing databases. 

The security of Linxens dLoc™ is its core functionality, and includes chip inventory management (digital track and trace system); digital signatures, user authentication and issuance control systems. Linxens provides full control of the issuance and verification systems and can detect any unauthorized chips by verifying the authenticity the chips and their data.
