I want to add some security funtion to the existing Indicator which you created for me

Hi, I want to lease my Indicator to my Trading group and require the following to be added to the script  

1. Define a list of I.P. addresses that are allowed to use the Indicator. I want to limit access to two users per I.P. address by counting the number of active licenses for each I.P. and rejecting additional requests once the limit is reached. 
2. Generate a license key for each user who leases the Indicator. You can use a combination of the user's email address, purchase date, and a random string to create a unique license key. 
3. Add an activation code to the script that users must enter to activate the Indicator. The activation code should be a one-time use code that is generated when the user purchases the Indicator. You can create the activation code by combining the license and secret keys.
4.  Check the license key and activation code when the Indicator is loaded. The script should verify that the license key is valid, has not expired, and has not been activated on another device. The activation code should also be validated by comparing it with the calculated activation code using the same secret key and cryptographic hash function. 
5.  Add maximum security layers to protect the Indicator.
