Lynx is an information security startup and the developer of the Lynx stamp, a product that secures paper-based documents with a digital signature using a handheld biometric IoT signing device.The entire cryptographic process is conducted on the Lynx hand-held signing device, which generates a digital signature based on the encrypted document’s content, the signer’s ID, and the event date and location.This digital signature, together with the URL to the cloud storage, is incorporated into a QR code which is printed on the physical document by the integrated printer in the Lynx stamp.
