Hi @shai-hulud...the method u suggest is what we call poor man's copyright. It is archaic. In countries with copyright act, the act takes precedence. In malaysia, what u suggested doesnt apply. The same goes for the US. As long as there is an act that prescribes the way a right must be protected it must be protected in that manner. In the context of Malaysian law, there must be registration by virtue of section 26. So that ousts the application of what you suggested. If the author does not register he is still able to insist on a moral right pursuant to section 25 of the copyright act. But protection is limited.
