How to Implement Geo-Fencing in Android & iOS Mobile Apps

Last updated July 22, 2024 by Appdome

Learn to Use Geo-Fencing in Mobile apps, in mobile CI/CD with a Data-Driven DevSecOps™ build system.

What is Geo-Fencing?

Geo-fencing provides mobile app developers with effective tools to enforce location-based access controls. This capability is particularly valuable for apps in regulated sectors such as finance, where meeting compliance and Know Your Customer (KYC) requirements is critical. Through geo-fencing, applications can restrict or allow access based on specific geographic regions. By implementing this feature, apps ensure adherence to regulations such as the US FFIEC (United States Federal Financial Institutions Examination Council), the EU’s GDPR (European Union’s General Data Protection Regulation), and Singapore’s MAS (Monetary Authority of Singapore). This targeted control reduces the risk of legal penalties and enhances compliance posture.

How Does Geo-Fencing Benefit Mobile Apps?

Geo-fencing on Appdome provides a robust defense mechanism against various security threats, including location spoofing and unauthorized access. It helps prevent:

  • Fraudulent Activities: Geo-fencing reduces the risk of fraud, such as fake transactions from high-risk or non-compliant regions, by restricting where the app can be accessed.
  • Fake Account Creation: In social and dating apps, geo-fencing can block users who attempt to register using spoofed locations, thus maintaining the integrity of the user base.
  • Regulatory Penalties: It ensures that apps do not operate in regions where they are not compliant with local laws, thereby avoiding fines and sanctions.

In addition, mobile app developers have the option to specify and manage the list of banned countries directly through the platform. This flexibility allows developers to customize their geo-fencing settings according to their app’s specific compliance needs.

Note: Ensure that your .apk or .ipa includes the following permissions.

Understanding the Geographic Data Sources for Geo-Fencing

To ensure transparency and accuracy in our geo-fencing capabilities, Appdome utilizes detailed vector maps from Natural Earth, specifically the “Admin 0 – Details” which focuses on sovereignty maps. “Admin 0” refers to administrative level 0 maps, representing sovereign states at their highest administrative level. These maps are crucial for defining the geographical boundaries used in our geo-fencing features, allowing us to adhere to the most accurate and universally recognized borders.

Additionally, for varying perspectives on geopolitical boundaries, we reference the “Admin 0 – Countries point-of-views” maps. While these maps are primarily categorized by country rather than sovereignty, they still include sovereignty attributes in their associated data. This careful selection of sources ensures that our implementation of geo-fencing respects international norms and accurate representations of territorial sovereignty.

Disclaimer About Banned Countries

The list of banned countries provided by Appdome is based on US, UN, and UK sanction laws. These sanctions can vary and may include different countries. The primary sources for these sanctions are:

The most economically sanctioned countries are:

  • China
  • Russia
  • Belarus
  • Republic of Congo
  • Iran

  2. Build the feature: Geo-Fencing.

    1. Building Geo-Fencing by using Appdome’s DEV-API:

      1. Create and name the Fusion Set (security template) that will contain the Geo-Fencing feature as shown below:
      2. fusion set that contains Geo-Fencing

        Figure 1: Fusion Set that will contain the Geo-Fencing feature
        Note: Naming the Fusion Set to correspond to the protection(s) selected is for illustration purposes only (not required).

      3. Follow the steps in Sections 2.2.1-2.2.2 of this article, Building the Geo-Fencing feature via Appdome Console, to add the Geo-Fencing feature to this Fusion Set.

      4. Open the Fusion Set Detail Summary by clicking the “...” symbol on the far-right corner of the Fusion Set. Copy the Fusion Set ID from the Fusion Set Detail Summary (as shown below): fusion Set Detail Summary image

        Figure 2: Fusion Set Detail Summary
        Note: Annotating the Fusion Set to identify the protection(s) selected is optional only (not mandatory).

      5. Follow the instructions below to use the Fusion Set ID inside any standard mobile DevOps or CI/CD toolkit like Bitrise, App Center, Jenkins, Travis, Team City, Circle CI or other system:
        1. Build an API for the app – for instructions, see the tasks under Appdome API Reference Guide
        2. Look for sample APIs in Appdome’s GitHub Repository
    2. Building the Geo-Fencing feature via Appdome Console

      To build the Geo-Fencing protection by using Appdome Console, follow the instructions below.

      1. Where: Inside the Appdome Console, go to Build > Geo Compliance Tab > Geo Compliance section.
      2. How: Check whether is toggled On (enabled), otherwise enable it . The feature Geo-Fencing is enabled by default, as shown below. Toggle (turn ON) Geo-Fencing, as shown below. Geo-Fencing option

        Figure 3: Use Geo-Fencing option
