copyright - Creative commons for academic library

I am building an online library, where professors will be submitting academic work (text and multimedia).

I want to find the right CC license. The work provided by the library can be shared and anybody can build upon it for commercial or non-commercial purposes, as long as they give credit to the professor. But the original work must remain un-edited. So, CC-BY-ND fits this description, but there is a part that worries me. If anybody can "remix or transform" the material, what is stopping them from changing the article and re-share it as their own, or claim that is the original?

Is there any way that CC-BY-ND protects me from this danger, or should I use another copyright licence?

Thanks
