A reliable date for your digital documents.
The creation date that appears in a digital document does not represent a “reliable date” that can be used as a reference. It is possible to modify this date as well as the content of a digital document without leaving a trace.
While the use of digital signature allows to identify the author of a digital document, the time stamp allows to attach a “reliable date” to a document in such a way that it is possible to know at what moment it was signed and if it has been altered later .
