Electronic signature
The electronic signature evidences the identity of the signatory and their consent to the content of the document.
Comparison
Electronic signature and integrity seal: distinct functions.
The two mechanisms address different needs and are complementary. Confusion between them is common and has practical consequences.
Delimitation of concepts
TRAMPTO seal
The integrity seal evidences that the content has not been modified since it was recorded, together with the date on which that occurred.
A signed document without a seal does not evidence which specific version was accepted. A sealed document without a signature evidences no consent. Together they cover both dimensions.
| Criterion | Electronic signature | TRAMPTO seal |
|---|---|---|
| Subject of the evidence | Signatory identity and consent | Content integrity and date |
| Prior identification | Required | Not required |
| Where the document is processed | Sent to the signature provider's servers | In the browser itself: only the fingerprint is recorded |
| Checking by third parties | Software or user account | Public link, no requirements |
| Cost model | Per signature or high-value subscription | From €0; unlimited for €1.99 per month |
| Time per document | Minutes, with a signatory workflow | Seconds |
| Value in proceedings | Evidence of consent | Evidence of integrity and of date |
Selection criteria
Electronic signature
- It must be evidenced that a specific person accepted the document.
- The procedure is subject to a legal signature requirement.
- Several parties are involved and must sign in a set order.
Integrity seal
- Documentation is issued that requires no signature but must not be altered.
- The recipient must be able to check it independently.
- It is material to evidence the date on which the document held given content.
- Volume of issue makes individual signature of each document unworkable.
Legal scope
TRAMPTO is a document integrity tool and not a qualified trust service provider within the meaning of Regulation (EU) 910/2014 (eIDAS). The seal constitutes technical evidence that a file has not been modified and of the date of its registration; it is not equivalent to a qualified electronic signature and does not replace one where a procedure requires it. In such cases a qualified provider should be engaged, without prejudice to also sealing the document.
