On my Master's I had an idea and made the following thesis proposing an new idea in order to offer a more user-friendly Privacy Enchanhing Technology, https://is.gd/YUUFLE .
Hence, in order to implement it, I decided to use it as a basis for a PhD in Japan via a MEXT scholarship. (I also do Japaneese language lessons as well to mitigate any language barrier as well.) But still I have this question:
Is good idea to use the academia and academic environment as a "tool" in order to implement the idea?
In other words instead of making a company that is a financially risky approach, in order to implement the idea of my master thesis, I thought an academic environment is more free-to-express to do so. Also I will consider the project sucessfull if I manage to make the average Joe to use it instead for making a profit of it (but I need some wage as well).
So having said that how do I approach an future supervisor and how I can make my supervisor also a "colaborator" in the project as well? Would just by saying that I have an idea would make any future supervisor unwilling to acept me for a PhD?
