Docuten allows you to sign with different types of digital signatures. Below we describe the legal aspects involved in each of the options provided.

Signature levels: Qualified electronic signature and advanced electronic signature

The legal validity of the digital signature is included in the European Regulation (Nº910 / 2014) of Electronic Signature, eIDAS , as well as in other international legislations. According to the European Regulation (Nº910/2014) on Electronic Signature, the following levels of electronic or digital signature are contemplated:

Qualified electronic signature:

  • Legally equivalent to a handwritten signature.
  • Obtained through qualified certificates.
  • Represents the highest level of electronic signature.

Advanced electronic Signature, equivalent to handwritten signature if it meets the following requirements: 

  • Linked to the signatory in a unique way
  • Allow identification of the signatory
  • Have been created using means that the signatory can maintain under his exclusive control
  • Linked to the data to which it refers to in such a way that any subsequent changes to it are detectable.

All the signature solutions that Docuten fit into one of these signature typologies, so they are legally valid and secure.

Centralized Signature: Legal Validity

With the entry into force of the European Regulation (Nº910/2014) on Electronic Signature (eIDAS) the centralization of keys is allowed, electronic certificates are stored on the server and can be used from any computer or mobile device.

  • The certificate remains in the custody of the signatory, because it can only be accessed with the password with which it was encrypted.
  • At the time of signing, a one-time message is sent to mobile phone or email (OTP), which must be indicated to complete the signature.
  • The certificate is kept on server, and no component will be required for its use.

With centralized signing, both qualified and unqualified certificates can be used:

  • Unqualified certificates issued by the digital signature platform. In this case, the signature will be an advanced electronic signature.
  • Qualified certificates issued by a Qualified Certification Authority. In this case, the signature will be a qualified signature . This solution is only available in the Docuten Enterprise Plan. (Contact us and we will clarify any doubts related to this plan).

Biometric signature: Legal validity

The Biometric Signature Document solution allows you to sign documents with full legal validity from a mobile device, tablet, or smartphone, for Apple, Android and Windows platforms.

The validity of the signature is given because the biometric traces of the signature are stored (Speed in X, Speed in Y, Acceleration in X, Acceleration in Y, Angular accelerations, Pressure variation / pseudo pressure, Number of strokes, Order of the strokes , Trace durations, etc) safely within the signed document.

Biometric data is encrypted on the application itself with the public part of an encryption key. The private part is stored by the Certification Authority or the Notary that generated it, and only upon court request is the private key used to decrypt biometric information. More information about the biometric signature.

Local signature: Legal validity

Local signature is done with qualified electronic certificates, which allows you to reach the highest level of signature, the qualified signature.

Electronic certificates can be generated using:

  • Cryptographic card
  • Software
  • USB Token 

Docuten’s on-premise signature solution is compatible with all operating systems and browsers, and has been implemented using Java Web Start (replacing the old applets).
