Integrity of the documents
- Can I send several files to be timestamped in a zip folder? Can I also, for example, put several logos in one single document?
- How much time is the timestamping protection valid for?
- What happens to my timestamped documents if Universign ceases its activities?
- Do complimentary stamps have the same probative value as those that are purchased?
- How can I be sure of the probative value of documents signed with the simple Universign signature?
- Does Universign guarantee the integrative preservation of my signed documents?
