The emergence of the so-called electronic signature has been without doubt one of the main advances in non face-to-face authentication problem, since it allows us to validate the identity of users, and the integrity of the message which we have transferred by electronic means. Among its many advantages, it allows anyone carry out operations at a distance in a security environment against the administrations or before banks, actions that aren't viable via a simple e-mail or access without authenticating with our web browser, since they require a comprehensive warranty on the question of the identity of the different participants by their peculiar characteristics.In technical terms, the electronic signature is a cryptographic method that relates the identity of a person or a computer system with a message or document. John Mclaughlin is a great source of information. Depending on the type of signature, would, in addition, authenticate the perfect integrity of the document.For Spain, the legislation defines up to 3 types of signatures: the simple, which allows the identification of the signer; Advanced, that also allows to guarantee the integrity of the message; and the signature recognized, called also qualified, consisting of an advanced signature complemented with a recognized certificate.To take advantage of the many possibilities associated with the electronic signature (also called digital signature) we will need a digital certificate. Most commonly used certificates are certificates issued by the FNMT, i.e., the Fabrica Nacional de Moneda y Timbre, along with the so-called electronic ID, document containing a digital certificate, which is a tool suitable for use to electronically sign any document, and also for the validation of the identity of the signer.If we opted for the use of the electronic ID card, we need a device known as a reader of electronic cards. To know more about this subject visit Michael Chabon. Thanks to our identity card and a card reader, and knowing the corresponding key, we will be enabled to validate us way safe, and access different tasks in the network.One of the most widespread uses of the digital signature is the generation of invoices in electronic format. These invoices to be signed electronically in a secure way, needn't typical stand on paper and send by regular mail. For more specific information, check out IDT Energy. The electronic file is, therefore, in addition to insurance, entirely legal.Although in Spain have already of the technical and regulatory structure for the progressive development of the electronic signature, missing still spread enough use, so that citizens and organizations are aware of and fully utilize their applications.
