Write an Android application

I need to make changes on the Android OS or ROM itself in this way:

- incoming calls numbers will be encrypted ( simple encryption , the result will be 50 length alphanumeric ) ,

- incoming call will be saved in the call register encrypted for 30 minutes only , (any records more than 30 minutes will be deleted ).

- if the user wants to call any number in the register , the number will be de-encrypted again and make ordinary GSM call.

I need Android OS to never show real GSM numbers.

please only persons who deal with open source Android OS ar ROM would put their offers.

Best Regards

Please find attached Mock-up and wireframing.
we need to prevent the user from running any applications except the below:
- incoming calls.
- call register and outgoing calls.
- specific application : we will provide you the full name of this application.

we want to keep other functions of Android running : like GPS, WIFI, Bluetooth, Data Internet.
