How to show a version of the project (photo, design) to a person and so that later the project could not be viewed again by him?

Question

Data protection

There is a developed design project (pdf-file, photos, etc.).
How to show this project to a person, but so that after the project is closed by a person, this project will not be available to him again?
Naturally, who shows and who looks remote from each other and communication via the Internet.
Is it possible to do this with some services, social networks and other Internet opportunities?
Maybe there is some clever mechanism?
It is clear that if a person is very suspicious of everything, then at the first viewing, he will print all the pictures and the entire project, save it locally and already have information.
But if a person does not suspect anything, and this is usually the case, just looks and acquaints himself, then he will not print anything. The goal is to show and leave what was shown to him, only in the far corners of his brain memory, to impress.

Answer 1

Teamviewer for remote demonstration. And in your case, only a live meeting.

Answer 2

Screen sharing on Skype, but it's better to make a low-resolution preview version with watermarks in the form of the words "not paid" and your details - enough to evaluate the work, but commercial use is impossible
