How do electronic signatures work technically?

An electronic signature is composed of electronic data and leaves no graphic representation on the document. The image on the document is merely symbolic. It doesn’t matter if it doesn’t look like the signatory’s handwritten signature. Its validity and probative force lie in the digital data incorporated into the document, which guarantees both its integrity and the authentication of the signatory:

  • A digital certificate provided by a trusted Certification Authority, which proves that the signatory’s identity has been verified;
  • A unique fingerprint of the file that ensures that the document has not been modified since it was signed.
