CERTUS digital seal technology



Issue and certify certificates with tamper-proof QR-codes

CERTUS® is a novel digital solution that enables document issuers like educational institutions, government bodies or notaries to secure value documents. It is a cost-effective next-generation security solution which sets a new standard in securing sensitive paper-based and digital documents, credentials and qualifications.


A new standard in securing value documents

CERTUS® sets a new standard in securing value documents, credentials and qualifications. It combines breakthrough digital seal technology, protected by the blockchain, with a secure QR-code applied to 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.



The digital security seal, secured by blockchain technology, protects and guarantees the integrity of the secured data. It seals a secured QR-code by creating a forgery-proof link to the code’s cryptographic signature.
