We have already highlighted in this blog that digital transformation is revolutionizing business management. This is particularly true in operations, as electronic invoicing has become, both out of obligation and devotion, a key element in optimizing processes and ensuring the integrity of transactions. In this context, the recognized electronic signature plays a fundamental role. So we have prepared this article to thoroughly examine everything surrounding a key term today: the qualified digital signature and its many benefits for any type of business.
What is a recognized or qualified electronic signature?
Therefore, the first step is to establish a definition of what a recognized electronic signature is. Likewise, it offers the highest level of security and authenticity in digital transactions. According to European Union regulations, it is one created using a qualified electronic signature creation device and based on a qualified electronic signature certificate.
The electronic signature recognized under eIDAS
There is also an official definition for qualified electronic signatures, which is included in the eIDAS or Regulation (EU) No. 910/2014 of the European Parliament and of the Council of July 23, 2014. This regulation concerns the electronic identification of digital transactions in the EU and serves as a common regulatory framework.
Its goal is to strengthen transparency and trust in electronic transactions in Europe, whether between citizens, businesses, or public administrations. In addition, eIDAS establishes the different types of legally valid digital signatures and the main requirements for each one. Specifically, on this official website you will find us listed as a Qualified Trusted Electronic Service Provider.
At a practical level, a qualified electronic signature guarantees that the identity of the individual or legal entity signing is verifiable. In other words, it is legally binding, ensuring the integrity of invoices so that, for example, no one can modify them and add a false IBAN to the invoice issuer. Therefore, it has a number of characteristics:
- Authenticity. Verifies that the person signing the document is who they say they are.
- Integrity. Protects the content of the document, ensuring that it has not been altered after being signed.
- Binding. Prevents the signatory from denying that they signed the document.
Specifically, these characteristics make it an essential tool for transactions that require high security and legal validity.
But are there different types of electronic signatures?
In turn, doubts and questions often arise about what types of electronic signatures there are and whether they are all valid or qualified. In this regard, you should know that there are several recognized types, which vary in the security and usability they offer.
Simple electronic signature
On the one hand, we are talking about simple electronic signatures. These can be as basic asscan of a handwritten signature or a click on an "Accept" button on an online form. Although easy to use, it offers the lowest level of security and authenticity.
Advanced electronic signature
On the other hand, advanced electronic signatures are more secure than simple ones, as it is uniquely linked to the signatory and allows them to be identified. In addition, any subsequent change to the signed data is detectable. A typical example is the use of a password, PIN, or token.
Recognized or qualified electronic signature
Qualified or recognized electronic signatures is the most secure form and complies with the strictest legal requirements. It is backed by a certificate issued by a trusted certification authority and uses a qualified electronic signature creation device.
How to obtain a recognized electronic signature?
The fact is that to obtain a recognized electronic signature, you must follow several steps that guarantee the authenticity and security of the process:
- Select a qualified certification service provider. In Spain, for example, the National Mint (FNMT) is a fully reliable provider.
- Request and verify your identity with personal information, official documents, and, in some cases, your physical presence.
- Receive your qualified certificate issued by the provider and linking the signer's identity to a specific cryptographic key.
In turn, to sign documents with a recognized digital signature, you need to use a qualified electronic signature creation device. These can be smart cards, USB tokens, or specialized software such as that offered by easyap , which guarantees the security of the signing process.
How to know if the electronic invoice you have is correct
What is obvious is that verifying the authenticity of an electronic invoice is very important in order to ensure the integrity of transactions. But would you know how to check if that digital invoice is correct? We give you several keys to detect it.
