Yes. The Universign signature service includes a cryptographic preservation procedure that guarantees the integrity of the signed document and the reliability of the signature elements for at least 5 years, no matter what storage system you use. Beyond this time period, if your signed documents are stored on the Universign platform, they will be subject to recurrent processing, ensuring their integrative preservation. Otherwise, to ensure the technological reliability of the documents signed in the long term, you should implement adequate internal or external procedures.
