SIGNERING, MED TRE STYRKOR

Europeisk lag erkänner tre typer av elektroniska signaturer. Deed gör alla tre och anger på varje signatur vilken du fick. En signatur vars styrka inte anges är en signatur som någon kommer att överdriva senare.

TIER 1 · SIMPLE
Simple electronic signature (SES), eIDAS Article 3(10)

Verified assent. The signer proved control of their email address and agreed in a timestamped record.

WHAT IT PROVES

That someone in control of this email address agreed to these terms at this moment, from this address and this browser.

WHAT IT DOES NOT

It is not uniquely linked to the signatory by a key only they hold, and it is not a qualified signature under eIDAS. A court weighs it as evidence, it is not presumed equivalent to a handwritten signature.

THE EVIDENCE KEPT
  • · One time code sent to the email address and consumed once
  • · Timestamp from the Deed server
  • · IP address and user agent at the moment of signing
  • · The exact text and language the signer was shown
01
TIER 2 · ADVANCED
Advanced electronic signature (AdES), eIDAS Article 26

Uniquely linked to the signatory. A key pair created in the signer's own browser signs the document digest, and a trusted authority timestamps it.

WHAT IT PROVES

That the holder of this private key, verified at this email address, signed exactly this document, and that the signature existed at the time the trusted timestamp authority states. Any later change to the document breaks the digest.

WHAT IT DOES NOT

The identity behind the key was verified by email, not by a qualified certificate issued after identity proofing. That is the line between advanced and qualified, and only a QTSP can cross it.

THE EVIDENCE KEPT
  • · A key pair generated in the signer's browser, private key never leaves the device
  • · SHA-256 digest of the canonical document, signed with ECDSA P-256
  • · The signer's public key, so anyone can verify the signature
  • · RFC 3161 timestamp token from a trusted timestamp authority
  • · A tamper evident sealed PDF carrying all of the above
02
TIER 3 · QUALIFIED
Qualified electronic signature (QES), eIDAS Article 25(2)

Issued by a qualified trust service provider. Legally equivalent to a handwritten signature across the European Union.

WHAT IT PROVES

That an identity proofed person signed with a qualified certificate on a qualified signature creation device. Under Article 25(2) it has the equivalent legal effect of a handwritten signature in every member state.

WHAT IT DOES NOT

Deed does not issue qualified certificates. This tier is completed by a qualified trust service provider through their own identity flow, and Deed records and verifies the result.

THE EVIDENCE KEPT
  • · Identity proofing performed by the qualified provider
  • · Qualified certificate on the EU trusted list
  • · The provider's signed document and validation report, stored against the Deed
TIER 3 · QUALIFIED

Issued by a qualified trust service provider. Legally equivalent to a handwritten signature across the European Union.

VARFÖR DETTA ANGES TYDLIGT

De flesta verktyg kallar allt för en signatur och låter dig anta den starkaste innebörden. Det antagandet spricker på det enda stället där det spelar roll, vilket är i en tvist. Så varje signatur här bär sin nivå, bevisningen bakom den, och den enkla meningen som talar om vad den inte bevisar.

VILKEN DU BEHÖVER

För en cred, ett tillstånd eller ett handslag mellan personer som litar på varandra räcker nivå 1 och tar en minut. För pengar, exklusivitet eller något du inte vill tvista om igen, signera på nivå 2. För fastigheter, bolagshandlingar och allt som ett register eller en bank måste godta, använd nivå 3.

VEM SOM HELST KAN KONTROLLERA DET

En signatur på nivå 2 publicerar sammandraget av den exakta text som signerades och undertecknarens offentliga nyckel. Återskapa texten, hasha den, kontrollera signaturen. Om Deed ändrades med ett enda tecken efter signering misslyckas kontrollen och säger det.

MINT IT. THEN SIGN IT.
