Copyright Registration is a legal process through which you register the official ownership of your creativity like book, painting, music, software, film etc. It protects the book, painting, music or film written by you from being stolen. If anyone publishes your book or painting in his name then he can be punished under the Copyright Act or you can present it as a proof in the court. https://gstregister.in/articles/recover-user-id-pass.php
