TimestampSever – Secure timestamp for document and data authenticity


Secure timestamp for document and data authenticity

The Utimaco TimestampServer is the ideal hardware security module for business applications that require proving the existence of a document or data at a specific point in time.

Whether this relates to the signature date of electronic contracts, the reception of offers on electronic tender platforms or the submission time for an online lottery – the Utimaco TimestampServer ensures the tamper-proof creation and authenticity of timestamps. It can be verified at all times whether the timestamped data existed in the exact same form at the point of time logged by the timestamp.

Periodical re-creation of a current timestamp guarantees continuity of the audit trail to enable long-term archiving – year after year, even after expiration of older signature certificates.
