The Creative Commons licence (CCL) is a copyright licence that allows the user, who is not the copyright owner of a work, to distribute freely an otherwise copyrighted work. In this context, a CCL works mutually for both the copyright owner and the end-user, since it gives the author the freedom to allow people to share, use, and build upon a work that he/she has created and protects the users from a possible copyright infringement claim. 

It is to be noticed that there are several types of CCLs and the users have to comply with the terms of distribution posed by the copyright owner and indicated by the respective CCL, otherwise they could be held liable for copyright infringement.
