Whats Discharge Like Pefore Period

Electronic Signature Model

be enlarging on this subject which is one of the pillars in Decree 47-2008, Act for the recognition of communications and electronic signatures.

Is that the same digital signature and electronic signature?
No, same thing. At first I thought yes, but looking for references found in several laws, has defined a digital signature and electronic signature. This digital signature that makes use of cryptography (in whole or part the message), thus ensuring the authenticity, integrity and non repudiation of the message.

To further clarify the definitions here:

electronic signature (copied verbatim from the decree 47-2008, section definitions )
data in electronic form in an electronic communication affixed to or logically associated with, that can be used to identify the signatory in relation to communication electronics and indicate the signatory's approval of the information contained in electronic communication.

For data could refer for example, a sound or mark that they are adhered to or associated with the document in order to indicate authenticity (intention to sign).


advanced electronic signature (copied verbatim from the decree 47-2008, section definitions)

electronic signature that meets the following requirements:

a) Be linked to the signatory only.

b) Allow the identification of the signer.

c) have been created using means that the signatory can maintain under his sole control.

d) be linked to the data referred to so that any subsequent change of the data is detectable.

With this we can conclude that the digital signature is a type of electronic signature ensures the authenticity and integrity of the message.
