DUUL in practice

The trustfulness of the storage

The trustfulness of the storage is based on the activities of processing, usage of a qualified time stamp and electronic signature. By fitting a document with a qualified time stamp, we confirm in what form the document existed before the time indicated in the stamp.

As long as this document contains also an electronic signature, likewise this electronic signature must be created and be valid before the stated time. By this we obtain a necessary proof about the time when the electronic signature was created, that means - important information necessary to prove the validity of the whole document.

In addition to the automatic verification of signatures or existing time stamps, DUUL will ensure the connection of a qualified time stamp and its regular renewal before it expires for the entire period of storage of electronic documents.
