Digital Receipt – Time Stamp Technology

When a user – or a company – transmits data – or a document – to the responsible authority, the latter must guarantee that these data (as well as the date and time of the transaction in particular) will not be modified. The responsible authority must therefore generate a « digital receipt ». The KSI Blockchain time-stamping technology allows to reach this objective for transactions between the user and the responsible authority, but also for internal processes within the Administration.

La Blockchain KSI

no data are published on the blockchain only their fingerprint

CERTUS® – The seal secured by the KSI Blockchain

The CERTUS digital seal technology is an essential building block to guarantee maximum security for documents generated by the responsible authority for users and companies. CERTUS allows us to offer new generation services and to make documents tamper-proof.

The document generated with the CERTUS QR code can be printed out while retaining its security and thus its original value. Digital documents validated by certificates often lose their official value if they are printed. The CERTUS solution allows for paper printing, which is inclusive by construction.
