Preliminary information
Before getting to the heart of the guide, going to explain how to insert image signature in PDF, there is some preliminary information about it that you need to know.
First, know that image signature in PDF is the simplest type of electronic signature existing. It can be created by starting by scanning an image of your signature on paper, but also by drawing it with the mouse pointer, a trackpad or with a graphics tablet. It has no inherent legal value (as it does not provide for the use of tools capable of guaranteeing the authenticity and integrity of the signed documents), so it is up to a judge to assess their authenticity, should it prove necessary.
On the other hand, the situation is different for the other types of electronic signature that exist. For example, there is the advanced electronic signature which is generated with means that allow to demonstrate the integrity of the document, over which the signatory has direct and exclusive control (eg a tablet) and has a certain legal value, except in real estate contracts.
Then there is the qualified electronic signature (o digital electronic signature) which is one of the most advanced forms of electronic signature and is applied with qualified tools, such as the signature kits that can be purchased from certification bodies, therefore it has full legal value and certifies both the originality and the integrity of the signed documents .
The signature I will talk about today, I repeat, is the "simple" electronic one, with no intrinsic legal value. If, on the other hand, you are interested in qualified electronic signature, read my tutorial dedicated to the topic.
