How do you prove you created something first?

The most reliable method is a qualified electronic timestamp from a QTSP listed on the EU Trusted List. Under eIDAS Art. 41(2), a qualified timestamp carries a legal presumption of accurate time and data integrity. It is generated by an independent trusted authority and cannot be altered without invalidating the timestamp. Self-generated evidence such as file metadata, email timestamps, and social media posts does not carry this presumption.

Is a file timestamp enough to prove creation date?

No. File system timestamps can be changed by anyone with filesystem access. Courts treat file metadata as unreliable standalone evidence of creation date. An email to yourself or a social media post creates a platform timestamp, but these are secondary evidence. A qualified electronic timestamp from an accredited QTSP is the legally reliable standard.

What is a qualified electronic timestamp?

A qualified electronic timestamp is a trust service from a QTSP listed on the EU Trusted List. Under eIDAS Art. 41(2), it carries a legal presumption that the date and time indicated are accurate and that the data has not been altered. The timestamp is generated using a trusted time source (RFC 3161) and cryptographically bound to a hash of the document. Swiss Trust Layer applies a qualified timestamp at sealing, starting at CHF 5 per document.

Does copyright registration prove creation date?

Switzerland and most EU countries do not have copyright registration systems, as copyright arises automatically under the Berne Convention. Where registration exists (such as in the US), a registration certificate provides evidence of the registration date, not necessarily the creation date. A qualified electronic timestamp is a more direct method of proving creation date.

What level of evidence do courts require for creation date?

In Swiss and EU civil proceedings, courts require independent evidence from a source that cannot have been manipulated by the claimant. A qualified electronic timestamp from an EUTL-listed QTSP satisfies this requirement: the QTSP is an accredited authority, and the timestamp is cryptographically bound to the document content, making retroactive alteration detectable.

Selon l'eIDAS Art. 41(2), un horodatage electronique qualifie beneficie d'une presomption legale d'exactitude de la date et d'integrite des donnees. Il est genere par un QTSP inscrit sur l'EUTL conformement a la RFC 3161. Swiss Trust Layer applique un horodatage qualifie a partir de CHF 5 par document.

Standard de preuve pratique

Les tribunaux cherchent des preuves independantes d'un tiers de confiance que le reclamant n'a pas pu manipuler. Un horodatage qualifie d'un QTSP inscrit sur l'EUTL satisfait cette norme.
