Time Stamp

The Qualified Electronic Time Stamp (QETS) provides a calibrated official time that certifies in a secure and traceable manner the existence of digital data, including content of an electronic document, before a certain point in time. Attached to a Qualified Electronic Signature, the QETS confirms that the electronic signature was created before the time specified in the QETS.

B-Trust issues QETS in accordance with Regulation (EU) 910/2014 and the standard ETSI EN 319 421 Policy and Security Requirements for Trust Service Providers issuing Timestamps.

The service allows checking if an electronic document for which an electronic time stamp has been issued has not been changed after the date and time of its authentication.

The service can be integrated into your environment to automate the process of time stamp validating. Please contact us for more information.
