Digital Seal
Technology
A new standard in securing value documents
CERTUS sets a new standard in securing value documents, credentials and qualifications. It combines breakthrough digital seal technologies protected by the blockchain with a secure QR-code applied to your documents.
The result is a QR-code marking which is impossible to tamper with or forge and secures both paper-based and digital certificates.
CERTUS enables independent and universal verification, safeguarding the value of holders’ documents and the reputation of issuing authorities.
State-of-the-art secure marking
The CERTUS tamper-proof QR-code protects the claim (the sensitive data) directly rather than the medium, making it an ideal solution for simple verification of paper and digital documents using widely available mobile devices.
The QR code contains the protected data in plaintext and a cryptographic signature, which acts as a indisputable mathematical proof of the link between the data to be protected and its digital security seal.
Digital security seal
The digital security seal protects and guarantees the integrity of the secured data. It seals a secured QR-code by creating a forge-proof link to the code’s cryptographic signature.
As documents are activated, the seal is secured by the blockchain to ensure its lifelong immutability. The seal contains only metadata such as the Issuer and the date of the activation.
The novel combination of the QR code and its digital seal makes the CERTUS security marking impossible to tamper with or forge and renders it universally and independently verifiable for life.
