What kglad said. That's not what Creative Cloud storage is for.
You probably just need a website to which you can upload images for online viewing. But owing to how the web works, nothing online can be fully protected. Web content is automatically downloaded to the end user's browser. And it doesn't take a genius to find it.
Password protection is an option but that doesn't stop people from grabbing screenshots or using browser add-ons to save content if they are so inclined.
Digital watermarks or barcodes that are invisible to the human eye are another option. And there is a Digimarc Photoshop plugin available for that (Digimarc fees apply).
