What is a digital signature?
The digital signature is simply a sequence of characters that is appended to the end of the body of a message to be transmitted under signature. It gives us the opportunity to inform, to faith and / or express a willingness in full legal compliance and security, without the need to be present for stamping on paper our handwritten signature. Digital signature uniquely identifies the person sending the message, makes sure that the message is exactly as it was issued at the time of receipt and that the signer does not have the opportunity to deny having signed the document. That is, a digital signature brings identity and integrity to a document and prevents repudiation at origin.
As examples of signed document standards, there is a PDF/A, which is a subset within the PDF standard dedicated to storage and long-term archiving of documentation.There are also several certification authorities such as Chambers of Commerce, the Government, CryptoApplet (version free software developed by the University Jaume I) and so on.

An ink signature can be easily replicated from one document to another using the copy of the image manually or digitally. The Digital Signature forces cryptographically to an electronic identity of an electronic document and can not be copied to another document. Paper contracts often have the ink signature block on the last page and previous pages can be replaced after a signature is applied. Digital signatures can be applied to an entire document, so that the digital signature on the last page, will indicate whether the manipulation of data in any of the pages have been produced.
In addition, the digital signature is becoming a de facto standard to reduce paper use in the current Information Society Digital Age, with consequent financial savings and positive impact on our environment.
