SMS based OTP has become standard in two factor authentication. At the same time, many useful applications forces end user to allow access to SMS. This poses a great threat to OTP based security system. Although advanced android OS like marshal mallow allows end user to disable such access manually, there is high degree of error due to frequent updates and application installation. Design a mobile app capable of detecting apps trying to access SMS in real time. The app should have a feature of allowing or blocking (single access, all access within a day/week/month, always) other apps from accessing SMS access.
Design such mobile app for Android and Microsoft.
Sample Data Required: Simulate OTP based messages to demonstrate the approach
