Mitigating Fraud with IP Geolocation

In the digital era, where online transactions are ubiquitous, fraud detection is a critical concern for businesses. A potent method to enhance security measures is through the use of IP geolocation. This approach involves identifying the geographic location of a user based on their IP address. In this blog post, we’ll delve into how businesses can utilize an IP geolocation API to flag potentially fraudulent activities and incorporate them into their fraud detection systems.

Understanding the Problem

Online fraud can manifest in various forms, such as identity theft, unauthorized transactions, and account takeovers. Fraudsters often use proxy servers, VPNs, or compromised accounts to mask their true location. This is where IP geolocation becomes invaluable. By determining the geographic origin of a user’s IP address, businesses can spot discrepancies, such as a login from a country different from the user’s usual location.

The Solution: ipapi.co’s IP Geolocation API

Our IP geolocation API can provide detailed information about the location of an IP address, including country and city. This data can be used to implement checks against unusual or suspicious activities. Here are a few scenarios where this approach is particularly effective:

1. Multiple Rapid Logins from Different Locations: If an account is accessed from geographically distant locations within a short time frame, it’s unlikely to be the legitimate user. For instance, a login from Paris just an hour after a login from Los Angeles should raise a red flag.
2. High-Value Transactions from Unusual Locations: For e-commerce platforms, a sudden high-value purchase from a location that’s different from the user’s usual transaction history can be suspicious. For example, if a user based in Toronto usually makes small purchases and suddenly there’s a large transaction from a different continent, it might warrant additional verification.
3. Accessing Sensitive Features from New Locations: When users access sensitive account features (like changing passwords or updating payment information) from a new location, it could indicate a compromised account. For instance, a user typically operating from Sydney who suddenly attempts to change their password from a location across the globe could be a sign of unauthorized access.
4. Inconsistent Shipping and IP Address Locations: In online retail, a discrepancy between the shipping address and the IP location of the order placement can be a sign of fraud. For example, if an order is placed from an IP address in South America but the shipping address is in Europe, this might necessitate additional verification.
5. Repeated Failed Login Attempts from Varied Locations: A series of failed login attempts from different geographic locations in a short span could indicate a brute force attack. For instance, multiple failed logins from different cities or countries over a few hours should trigger a security alert.

Integrating the API

It’s really easy to integrate Kloudend’s IP geolocation service. You can find detailed API usage documentation along with code snippets at https://ipapi.co/api/ . Here’s an example of how you might use the API:

API Endpoint :

# Get the location of the machine that makes the API call
https://ipapi.co/json/

or

# Get the location of a specific IP address
https://ipapi.co/$IP_ADDRESS/json/

Code Example

Let’s consider a Python example where we integrate the IP geolocation API to check the location of an IP address:

import requests

def get_geolocation(ip_address):
    url = f"https://ipapi.co/{ip_address}/json/"
    response = requests.get(url)
    if response.status_code == 200:
        return response.json()
    else:
        return 'Error ! Please contact us.'

def check_for_fraud(user_ip, user_profile):
    location_data = get_geolocation(user_ip)
    if location_data:
        user_country = user_profile['country']
        ip_country = location_data['country']
        if user_country != ip_country:
            flag_for_manual_review(user_profile, user_ip)

def flag_for_manual_review(user_profile, ip_address):
    # Implement the logic to flag the user profile for manual review
    print(f"User {user_profile['username']} flagged for manual review. IP: {ip_address}")

# Example Usage
user_ip = "1.2.3.4" # Replace with the actual IP address
user_profile = {"username": "john_doe", "country": "US"}
check_for_fraud(user_ip, user_profile)

In this example, the get_geolocation function fetches the geolocation data for a given IP address. The check_for_fraud function then compares this location with the user's profile data. If there’s a mismatch, the account is flagged for manual review.

Best Practices

• Data Privacy Compliance: Ensure compliance with data privacy laws like GDPR or CCPA when using IP geolocation data.
• Thresholds and Patterns: Set up thresholds and recognize patterns in login attempts to reduce false positives.
• User Communication: Inform users when suspicious activity is detected and involve them in the verification process.
