What is a digital signature? And what is the difference with an electronic signature?
A digital signature is an encrypted electronic signature that can guarantee the origin of an electronic document, its integrity, and its authenticity. When you manually sign a document, you guarantee your agreement to the text content. A digital signature does the same thing and adds even more information. It guarantees signature authenticity by proving that you are the person who signed, it ensures document integrity, meaning that it has not been modified since the signature, and also confirms that the sustainability of the document, ensuring its validity for years to come.
Difference between a digital and an electronic signature :
An electronic signature consists of blocks of information that identify you. A digital signature is a form of electronic signature that is more secure because it is encrypted and can be invisible. It protects many elements of your documents.
What is a digital identity and how is it used?
A digital identity uses technological conventions to link digital identifiers to a person’s attributes. A digital identity guarantees that a given person is at the other end of the transaction or the origin of a signed document. For example, a digital identity can be used to sign birth certificates, passports, university transcripts and diplomas, contracts, technical plans and drawings, and affidavits. In short, a digital identity can be used to sign any document whose proof of origin may be required for weeks, years, or even decades to come.
What is a digital signature certificate and what type of information does it contain?
The digital signature certificate can be compared to a passport. It contains information that helps authenticate the signer’s identity and links them to their digital signature. All recipients can see the certificate’s details by accessing Notarius’ online certification servers. Certificates are issued by Notarius, a certification authority, once a user’s identity and, when applicable, professional status, have been verified. The certificate is an electronic file that meets the X.509 standard and is signed by a recognized certification authority. It contains data that identifies the user, such as:
- The user’s distinctive name (last name, first name, and, when applicable, member number)
- The name of the user’s professional association, when applicable
- The user’s email address
- The user’s public verification key
- The certificate’s validity period
- The certificate’s serial number
- The issuing certificate authority’s digital signature to verify and guarantee the authenticity of the information contained within the certificate
Moreover, the certificate contains a public verification key that matches the private signature key. Together, they create a link between the user and the asymmetric key pair.
Can someone modify or alter a signed PDF document?
A signed document can be marked up but cannot be easily altered. If a digitally signed document were to be altered, the digital signature would be removed from the file, thus rendering the document a copy of the original. For example, in paper form, a wet signature original can be photocopied, thus creating a copy of the original and this copy can be easily modified and altered. The same is true for an original electronic PDF with a digital signature. It can be “reprinted” as a PDF and the new document then becomes a copy of the original. This copy can be altered but, for the recipient, it is a copy since the digital signature is no longer part of the PDF.
