Electronic signature

An electronic signature (ES) is information attached or otherwise logically connected to an electronic document signed in an online environment, with the help of which it is possible to identify the natural person who created the electronic signature. An electronic signature represents a basic level of authentication of a natural person, while it does not represent legal certainty and may not always provide strong evidence of the signer’s identity. A certificate for an electronic signature is required to use an electronic signature that is capable of electronically signing electronic documents. The issuer of such certificates for electronic signature is the certification authority, i.e., the company that charges customers fees for providing these services.

Signing a loan application through a bank application, an electronic request to change an insurance company, an invoice delivered via e-mail. Digital documents and electronic communication are commonplace in various industries today. How is it that many things that in the past required personal contact can now be handled remotely? And are digital signing and electronic communication safe at all?
We consider the terms “improved electronic signature” and “advanced electronic signature” interchangeable and refer to the same thing, namely an advanced electronic signature that meets the requirements set forth in the European regulation eIDAS (Regulation No. 910/2014).
Simple, advanced and qualified electronic signatures differ mainly in the legal certainty they offer. The higher the level of legal certainty, the more suitable a particular level of electronic signature is for securing transactions of higher value. Of course, there is also a difference in the process of verifying the identity of a person or entity when issuing a certificate for a given signature.
