According to the eIDAS regulation, there are three types of signature:

• simple;
• advanced electronic;
• qualified electronic;

(REGULATION (EU) No. 910/2014 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 23 July 2014, Art. 3 para. 10, 11 and 12)

A Digital Signature is the electronic equivalent of a traditional handwritten signature on paper. Permanently associated with the electronic document to which it is affixed, it enriches it with information that certifies with certainty its integrity, authenticity and non-repudiation, giving the document full evidentiary effectiveness.
(Digital Administration Code - 7 March 2005).

The Remote Digital Signature service allows digital documents to be signed in conditions of maximum security but without the use of a Smart Card or the installation of dedicated hardware.

According to the provisions of art. 15 of Law 59/97: "the acts, data and documents drawn up by the Public Administration and by private individuals by computer or telematic means, the contracts stipulated in the same forms, as well as their filing and transmission by computer, are valid and relevant for all legal purposes". For practical purposes, it is sufficient to use signature reading software (e.g. Acrobat Reader) to check the validity of the signatures affixed.

Electronic signatures are regulated as follows:

• in the EU, by eIDAS - Regulation (EU) No. 910/2014 of the European Parliament and of the Council of 23 July 2014 on electronic identification and trust services for electronic transactions in the internal market and repealing Directive 1999/93/EC;
• in the US by ESIGN - The Electronic Signatures in Global and National Commerce Act (E-Sign Act) (2000), and UETA - The Uniform Electronic Transactions Act (1999).

The main difference between the EU and the US is that US law does not distinguish different types (levels) of electronic signatures. EU law distinguishes between electronic signatures, advanced electronic signatures and qualified electronic signatures.

Similar acts have been passed all over the world, making digital signatures a legal and reliable way to execute contracts and other documents. Electronic signatures are legally valid, binding and enforceable in almost every developed country in the world.
