Not sure if this is the right place to ask but maybe some of you guys have a tip: I am looking for an online service where I can upload documents and give limited access to certain people. That means access is time-limited, for example 6 hours it is not possible to save or print the documents or take screenshots. Of course there will always be a hack to bypass any protection. But lets just say that the person is technically not skilled and has little time he should not be able to bypass the protection easily. anyone knows of a service like that?
