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.
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.
