How to protect my EA file on VPS ?



there is a way to hide my EA file or secure it with password ? 

i want to connect a customer to my EA I open a vps that run the MT5 and the file of my EA is there ,the  customer have  access to the vps 

i dont want that the customer will have access to my EA file ( now he can go to the folder and copy this file ) 

or maybe there is other way ? i have to  give the customer access to the vps  because he need to connect his account of MT5 



you could program a license server and connect your EA to that or you check the account number in the EA:

int accountNumber = AccountInfoInteger(ACCOUNT_LOGIN);

Or you give your customer only the investor password, so your application can run in the vps and he could see the account on his system.
