How to Prove You Created Something First

Under the Berne Convention, copyright arises automatically at the moment of creation. No registration, no formality required. But this automatic right creates a practical problem: there is no public record of when you created something. When a dispute arises, the burden falls on you to prove creation date, and the methods you used to document that date determine whether your claim holds up in court.

Methods That Do Not Hold Up

• File system timestamps: The "created" and "modified" dates on your hard drive can be changed by anyone with filesystem access. Courts routinely discount file metadata as standalone evidence.
• Email to yourself: Email headers can be spoofed and content is not independently verified by any trusted third party. Secondary evidence at best.
• Social media posting: Platform timestamps are controlled by the platform, can be altered through platform errors, and provide circumstantial evidence, not proof.

Methods That Hold Up in Court

1. Qualified Electronic Timestamp (eIDAS Art. 41)

Under eIDAS Art. 41(2), a qualified electronic timestamp has a legal presumption of the accuracy of the date and time it indicates and the integrity of the data to which it is bound. The timestamp is generated by a QTSP listed on the EU Trusted List, synchronized to a trusted time source under RFC 3161, and cryptographically bound to a hash of the document. No one can alter the document content without invalidating the timestamp.

Swiss Trust Layer applies a qualified electronic timestamp at the moment of sealing, anchored by a QTSP under RFC 3161. The signed document carries the timestamp in its PDF metadata and can be verified at validate.swisstrustlayer.com. Pricing starts at CHF 5 per document.

2. Notarial Certification

A notary can certify the date of creation by witnessing the signing of a document that includes a hash or description of the work. This is legally reliable but expensive and geographically constrained.

3. Depositing With a Collecting Society

Organizations such as SUISA (music) or ProLitteris (text and image authors) in Switzerland accept deposits of creative works with date evidence. These provide independent third-party confirmation of creation date for specific creative categories.

The Practical Standard for IP Disputes

In Swiss and EU IP disputes, courts look for independent evidence from a trusted third party that cannot have been manipulated by the claimant. A qualified electronic timestamp from an EUTL-listed QTSP satisfies this standard. Self-generated evidence does not.

Step-by-Step: How to Create Verifiable Proof

1. Upload your document to Swiss Trust Layer at swisstrustlayer.com.
2. Apply a qualified electronic seal. The platform generates a SHA-256 hash and binds it to a trusted timestamp from an accredited QTSP under RFC 3161.
3. Download the sealed PDF containing the certificate chain, timestamp, and document hash.
4. Store the sealed document. If your creation is disputed, provide the sealed PDF and the verification URL. Any party can verify at validate.swisstrustlayer.com without an account.
