What's An Advanced Electronic Signature? How Does It Work

Advanced electronic signing is one way to confirm identity and accept the content of document methods. This type of electronic signature, however, is not the only one.

Digitalization allows companies and institutions to establish contractual relations with their audience without having to physically appear at an office or branch.

This article will concentrate on advanced electronic signatures to understand their features and how they work. We also review the concept of electronic signatures and examine the differences between advanced electronic signatures and other digital signature formats.


A legal definition is a basis for an electronic signature. It is digital/electronic equivalent to a handwritten signature traditional idea. This signature represents a subject and indicates the will and acceptance of a text by it.

Electronic signature allows the traditional process to be 100% online. It consists of a series of encrypted data that is attached in an electronic message with full integrity.

This technology relies on several methods for signing documents. This involves the identification verification of the signatory subject and subsequent signature registration. The contract acceptance by the same person is also part of this process.

Different methods are used in the first part of this process such as facial Biometrics and cards of coordinates to verify the identity and signatory subject. In the second, various cryptographic technologies are used to guarantee the reliability and subsequent inviolability the time stamp, document, and to link the signature to the identity and signer.


An advanced electronic signature refers to an esignature that matches or ensures singing according to a set of technical requirements and legal requirements as per the reference regulation in electronic signing eIDAS. We will talk more about this later in the article.

An advanced electronic sign must comply with the following requirements:

  • It must be linked with the signer's id in a unique, non-transferable.
  • It must permit identification.
  • It must be created with data that the signer has access to using trust. has sole control
  • It must be linked with the data in the signed document to prevent any future modification.

These advanced electronic signatures provide high-level security in contracting and signing processes. Its key feature is the integrity and authenticity of the signed content. This type of esign ensures that signed documents have not been altered or that signers are still the same person.

There are still daily processes that need to be digitized and that require high levels of security. This is something advanced electronic signature grants for other types.

  • Bank account, high-level contracting, mortgages, pension plans, direct debits, etc. Any sector.
  • The mobility and tourism sectors have different procedures (check-in at hotels or border procedures). These are the most important.
  • The processes of electronic management and other related to citizen collaboration.


The most popular type of signature is the advanced electronic signature. This electronic signature is distinguished from the two other types of signatures: qualified electronic signature and simple electronic signature.

The primary difference between a simple electronic signature and an advanced one is the identification of signatory person. It is not necessary to create an electronic signature pattern for simple esignature. However, in advanced esignature it is a mandatory requirement. This critical factor is required for contract signing. In cases where there are high-security requirements for these types of risk-operations, the law also requires that high-security criteria be used.

Both have the same features and uses as the advanced in relation to their relationship with an electronic qualified signature. The creation of the signature is the key. The signature must be created using a qualified electronic signature device. This hardware must meet certain requirements.


Europe is the leader in electronic signature regulations in the world. These standards are also replicated in other countries. Regulation 910/2014 is also known as eIDAS. It sets the foundation for electronic signatures and online trust services.

eIDAS organizes all aspects of electronic transactions including advanced electronic signature. 5AMLD Regulation (5th anti-money laundering Directive) is in the same vein as eIDAS. It creates a unique space in Europe for digital sector and improves users lives.


Mexico is like other countries. Mexico, despite not having adopted specific laws on electronic signatures such as Europe, still considers in its legal regulations the validity and legality advanced electronic signature. This serves as an instrument for trust and security for Mexican users and businesses.

The Federal Civil Code Article 1803 states the following: It is express when the will can be expressed verbally, in writing by electronic, optical, or other technology or by unambiguous signs.
