Docuten allows you to sign with different types of digital signatures. Hereafter we are going to describe the legal aspects referred to all the different signature services offered by Docuten.

Signature levels: Qualified electronic signature and advanced electronic signature.

The legal validity of the different types of electronic signature is compiled in the European electronic signature regulation (Nº910/2014) also called eIDAS and other international laws. According to the European regulation, these are the following levels of electronic or digital signatures :

Qualified electronic signature :

  • Legally equivalent to the handwritten signature.
  • Obtained through qualified certificates.
  • Represents the maximum electronic signature level.

Advanced electronic signature (Equals to handwritten signature if it fulfills these requirements) : 

  • Needs to be affiliated with the signer personally and specifically
  • Allow the signer identification
  • Had been created using channels the signer can keep exclusively under his control
  • Being linked to the data referred , meaning that when any change is made to the information it will remain reflected on the record.

All the signature solutions allowed by Docuten fit in one of these types of signatures, what makes them fully valid and secure.

Centralized Signature : Legal validity

With the entry into force of the European Regulation of Electronic Signature (Nº910/2014) centralization of the passwords has been approved. Now, electronic certificates can be saved within the server of the company and used from any computer or mobile device.

  • The certificate remains under the signer custody, and it will only be accessible with the password the certificate has been set up with.
  • During the signature process a one time password text message will be sent to the signer mobile phone or email address. This code must be inserted to finish the signature process.
  • The server keeps the certificate safe and won’t need any external component for its use.

With centralized signature you can either use qualified or non qualified certificates.

  • Non qualified certificates, issued by our digital signature platform. In this specific situation, we are talking about an advanced electronic signature.
  • Qualified certificates, issued by a Qualified Certification Authority. In this case, we are talking about qualified signature. This solution is only available for those who hire the Enterprise service plan of Docuten. (Contact with us and we will solve all your doubts).

Biometric Signature : Legal validity.

Biometric signature solution by Docuten allows the customer to sign documents with fully legal validity from any mobile device, tablet or smartphone, for the Apple, Android and Windows platforms.

Signature legitimacy comes from the information securely encrypted in the signature, the biometric strokes of the signature itself. (Speed in X, Speed in Y, Acceleration in X, Acceleration in Y, Angular accelerations, Pressure variations and pseudo-pressure, stroke numbers, stroke order, stroke duration, etc).

Biometric public data is encrypted within the same application used to sign, protected by an encryption key. The private part of the information is kept by the Certification Authority or the notary that has generated it. Only under a judicial petition this information will be used in case there are doubts about who really made the signature (More information about the biometric signature).

Local signature : Legal validity

Local signature is the one made with the qualified electronic certificates, what allows to reach the maximum signature level, the qualified signature.

Electronic certificates could be generated for :

  • Smart Card
  • Software
  • Token USB

The local signature solution of Docuten is compatible with all the operative systems and browsers and has been implemented via Java Web Start ( Replacing old applets).
