What is this functionality for?

In order to ensure full future compatibility of documents signed via the Autenti platform, we operate on the basis of global standards of security, encryption and data saving. All signatures and seals created via the Autenti platform are marked with a qualified electronic time stamp, along with data allowing for long-term validation of the LTV (Long Time Validation) signature. You can verify the validity of the submitted e-signatures at any time in the future.

When applying a qualified signature or Autenti seal, LTV is added automatically, allowing you to maintain a chain of trust ensuring the validity of signatures long after the expiry date of the signing certificate.
