Digital time stamps according to eIDAS as qualified document verification

  • Legal proof that the document has not been changed after the time stamp
  • Time stamps from qualified trusted service providers, e.g. D-TRUST
  • Very high evidential value according to EU regulation eIDAS-VO
  • Internationally standardized (RFC 3161)
  • Easy use of time stamps with digiSeal software and integration into processes

Motivation

Changes in document content or data are not readily apparent in the digital world. Nevertheless, archived documents, such as patient files, personal status data or payment-relevant documents with social insurance carriers, must still be able to prove their original condition even after a long period of time.

Solution

An electronic timestamp is the appropriate tool to meet this requirement: It reliably confirms that certain digital data or documents were available at a certain time in this way and not otherwise. The time stamp is not determined by a local computer, but is generated by a qualified trust center and is therefore based on official time. Qualified providers, such as D-TRUST (Bundesdruckerei’s trust centre), guarantee that the time stamps they issue can be verified over a period of 30 years.

Background information: Secure time source

The time specification at D-TRUST is synchronized with the German DCF 77 time signal. Typically the maximum deviation is less than 100 ms, in case of time signal failure a maximum of 500 ms within 48 hours.
