Technical Overview

This documentation is especially for developers who want to join our project and for everybody else who would like to know how AIMSICD detects IMSI-Catchers, silent SMS and other threats. Important Note: Due to its complexity, this is a work in progress.

###Basic Modules and I/O:

###Database Tables: (Current Behavior)

• DEFAULT_MCC_TABLE: (Mobile Country Code): This table holds data to identify your service provider (carrier) and country.
• CELL_TABLE: These are the unique BTS towers as collected by the phone, once it has connected to it (ignoring neighboring cells).
• LOCATION_TABLE: These are the individual measurements as collected when in Tracking Cell Details mode. The location (Lat/Lng) of the phone and the Cell-ID it is connected to + timestamp.
• OPENCELLID_TABLE: Downloaded DB from OpenCellID.
• SILENT_SMS_TABLE: Protocol of incoming messages.

Database Tables: (New Proposal)

To be updated

• CELL_TABLE: Data collected by the phone when it is connected to a cell. (not from the table neighboring cells).
• LOCATION_TABLE: These are the individual measurements as collected when in Tracking Cell Details mode. The location (Lat/Lng) of the phone and the Cell-ID it is connected to + timestamp.

Other important details:

Display the Neighboring Cell information in two ways:

1. through telephony manager methods which does not work on Samsung Devices
2. a fallback is available through the methods developed by Alexey (Data is saved in an Array not in an table)
