The Importance of Documents

Beyond being recognized as a trusted leader in digital signatures, we feel it is important to define the very concept of a document. Documents. There are many definitions of a document, and these vary according to the context: A lawyer will refer to legal texts, a linguist will consult a dictionary, Wikipedia will discuss epistemology, and so on. To keep things concise, we simply define a document as a set of static information that can be read in a linear way by a human being. Electronic documents. From this definition, we specify that an electronic document is a document supported by an electronic medium. It can be supported by a variety of media. There is a wide range of media, such as Word, Excel, PDF, PSD, XML, etc. Official documents An official document is a document that, by its very nature and function, requires a high degree of reliability. These requirements can mainly be broken down into the following four categories:

  • Origin: It is important to be sure of the signatory’s identity, organization, professional status, the time and date at which the document is finalized and the geolocation of the signature.
  • Integrity: It is important to ensure that the document has not been altered since it was finalized.
  • Authenticity: Information providing proofs of origin and integrity are embedded in the document.
  • Longevity: The document can be opened and read, its origin confirmed and its integrity verified over a long period of time.

The official document always incorporates the first three requirements—origin, integrity and authenticity—and only incorporates the longevity requirement in certain cases. Notarius is a trusted third party providing proven and recognized solutions aimed at making official electronic documents reliable through digital signatures or “qualified electronic signatures.” As a trusted leader, we certify the origin of the document as well as its integrity, its authenticity and, where appropriate, its longevity.
