A digital security seal is used to seal the QR code and make it tamper-proof by creating a forgery proof link with the QR code’s cryptographic signature.
The seal is timestamped on the KSI blockchain, making the sealed document credentials immutable for life and independently verifiable without the need for a third-party guarantor.
The seal contains only metadata such as the issuer name and the date of activation. Personal and sensitive information are never stored directly, nor encrypted, in any database or on the blockchain.
The combination of QR code, digital seal and timestamping on the blockchain makes the CERTUS® security marking virtually impossible to tamper with or forge. It makes it universally and independently verifiable for life.
