Copyright is the author's exclusive right to prevent copies of his work from being made without authorization. This right arises through the deposit of the work. It is therefore an exclusive economic right of the author who may have a certification attesting to ownership and the filing date. Copyright is therefore a part of the broader right of the author who protects the idea since its creation, also attributing the moral right. In view of the difficulties that may arise in attributing the authorship of the work, it is appropriate to be able to activate the registers that certify it unequivocally.
