Copyright and neighbour rights
There is no official public register in which copyrighted works are entered with the effect that everyone else is aware of who the author is and the copyright holder as well as which is the content of the rights. This is achieved primarily through non-disclosure agreements, statements of authorship and other individual legal actions.
