Characteristics of Digital Signature in relation to Electronic.

In the increasingly digitized world of 2024, the need to understand the differences between digital and electronic signatures has become crucial for individuals and businesses across all sectors. Both are widely used to formalize documents and carry out electronic transactions, but they have different characteristics that determine their applications.

Digital Signature: Security and Authenticity

The digital signature uses encryption technology to link the holder of the digital certificate to the electronic document. It guarantees admissibility and legal validity in accordance with Article 10, §1 of Provisional Measure No. 2,200-2/2001, established by ICP-Brasil.

Digital Signature Featuresl:

  • Cryptography: Uses encryption to ensure the security and integrity of documents.

  • Uniqueness: Each digitally signed document is unique, even if the signatory is the same.

  • Legal Validity: It is sufficient to confirm the legal validity of an electronic document.

  • Authenticity and Integrity: Guarantees authenticity, integrity, reliability, irreversibility and undeniable authorship of the document.

  • Link to the Document: The signature is fully linked to the document and any change invalidates the signature, removing its probative value.

  • Long-Term Security: Digital signature generation and verification processes guarantee the recovery and legal determination of their authorship and integrity in the medium and long term.

Electronic Signature: Flexibility and Efficiency

The electronic signature, on the other hand, does not use a digital certificate, but requires authentication methods to verify the identity of the signatories in accordance with Art. 10, §2 of Provisional Measure No. 2,200-2/2001.

Electronic Signature Features:

  • No Digital Certificate: Does not require validation by a public key infrastructure chain.

  • Technological Authentication: Uses mechanisms such as login, password and additional information to prove your legitimacy.

  • Authenticity: It must allow the secure identification of signatories and guarantee the expression of the will of the parties.

  • Integrity: Must be secure and non-alterable from creation, transmission or storage, with mechanisms to identify changes.

  • Timeliness: Records date and time of signature from a reliable source, influencing prescriptive or expiry dates.

Understanding the differences between digital and electronic signatures is essential in 2024 to ensure the security, validity and efficiency of electronic transactions and documents. Both offer distinct advantages that must be considered according to the need and context of use.

Regardless of the platform acquired, the important thing is to analyze whether they have the necessary certifications, and the ICP-Brasil seal that guarantees the compliance of electronic validation platforms.
