Copyright protection is not per se a human right, but it is a tool which protects the human rights of authors and publishers. Copyright impacts on freedom of expression, both of the author and of members of the public who wish to distribute the author’s works as part of their own freedom of expression. This does not just mean the freedom to express a certain opinion, but also to chose the appropriate medium to do so, or even to remain silent.
