ShadowDevice Tracking Methods

ShadowDevice employs multiple tracking methods to ensure accurate and reliable location data. This article explains how ShadowDevice tracks via GPS, Wi-Fi, and Location-Based Services (LBS), along with the details and nuances of each method.

1. GPS Tracking

• ShadowDevice uses Global Positioning System (GPS) to determine precise locations by receiving signals from satellites.
• At least three satellites are required to obtain a valid GPS point.
• For each GPS point, we obtain:
  • Latitude and Longitude coordinates (plotted directly by us).
  • Number of GPS satellites connected.
  • GPS speed. (This is no longer displayed on location information)

Details:

• We do not send lat/long coordinates to Google; we plot these directly within our system.
• A higher number of connected satellites generally means more accurate location data.
  

Example:

• Location: 40.7128° N, 74.0060° W
• Satellites: 4
• Speed: 5 m/h

2. Wi-Fi Tracking

How It Works:

• ShadowDevice utilizes surrounding Wi-Fi networks to determine location.
  
• We do not connect to any Wi-Fi networks; we only sniff for the MAC addresses (unique identifiers for Wi-Fi networks).
• A minimum of three MAC addresses (unique identifiers for Wi-Fi networks) are needed.
• These MAC addresses are sent to Google, which converts them into latitude and longitude coordinates. Google then sends these coordinates back to us for plotting.

Details:

• Google can sometimes return "Google Unable To Locate," which means:
  • Google was unable to determine the location from the provided MAC addresses.
  • Possible reasons include insufficient Wi-Fi signals, the networks not being in Google’s database, or network issues.

Additional Information Collected:

• Wi-Fi accuracy (measurement of how close the estimated location is to the actual location).
  
• Battery percentage, charging status (Yes/No), signal strength, and zone status.

Example:

• MAC Addresses: [00:14:22:01:23:45, 00:14:22:01:23:46, 00:14:22:01:23:47]
• Returned Location: 34.0522° N, 118.2437° W
• Accuracy: 20 meters

3. Location-Based Services (LBS)

How It Works:

• LBS is used when GPS and Wi-Fi are unavailable.
• It determines location based on cellular network data, using cell towers.

Details:

• Less accurate than GPS and Wi-Fi but useful in areas with poor satellite visibility or Wi-Fi coverage.

Additional Information Collected:

• Battery percentage, charging status (Yes/No), signal strength, and zone status.

Example:

• Estimated Location: 37.7749° N, 122.4194° W
• Accuracy: 100 meters
