Alternative data – Enhancing accuracy in fraud detection


Traditional fraud detection methods are struggling to keep up with increasingly sophisticated tactics, creating a pressing need for more robust and adaptive systems. This is where alternative data emerges as a diverse reservoir of information capable of revolutionizing fraud detection strategies. By harnessing non-traditional sources, organizations can significantly enhance the accuracy, efficiency, and predictive power of their fraud detection mechanisms.

This article explores how alternative data can strengthen detection models, introduce new security paradigms, and transform risk management approaches. Whether you’re a data scientist, risk manager, or simply interested in the future of fraud detection, you’ll find valuable insights into this cutting-edge domain.

What is alternative data?

Alternative data refers to information gathered from non-traditional sources, distinct from conventional financial and transactional data typically used in fraud detection and risk management. Unlike traditional data, which is structured and comes from well-known databases like credit scores and banking records, alternative data originates from diverse, unconventional sources. By incorporating this broader spectrum of data, organizations can significantly enhance the accuracy and predictive power of their fraud detection systems.

Main types of alternative data

Alternative data encompasses a variety of non-traditional sources that can significantly enhance fraud detection mechanisms when effectively utilized. While these data types differ in origin and structure, they share a common goal: to provide deeper insights into behaviours, activities, and trends that traditional data alone might miss. The main types of alternative data include:

Behavioural data

Behavioural data provides insights into how individuals interact with digital platforms and services. By analyzing user behaviours, organizations can detect patterns that deviate from the norm, indicating potential fraudulent activity.

  • Social media activity: Analyzing posts, comments, and interactions to assess risk profiles and detect fraudulent behaviours.
  • Clickstream data: Tracking users’ navigation patterns on websites to identify unusual or suspicious actions.
  • Social sentiment and product reviews: Monitoring sentiment analysis and user reviews to detect coordinated fraudulent activities or fake reviews.

Geospatial data

Geospatial data involves information about the physical location and movement of individuals. This data type helps verify user locations and detect anomalies that may suggest fraudulent activities.

  • Geolocation data: Adopting GPS data to verify user locations and detect anomalies in movement patterns.
  • Travel logs: Monitoring travel patterns to identify inconsistencies that could suggest fraudulent activity.
  • Satellite imagery: Employing satellite data to verify physical changes at locations, detect fraudulent claims, and assess large-scale activities.

Transactional data

Transactional data captures details of financial and commercial exchanges. By scrutinizing these transactions, organizations can identify irregularities that might indicate fraud.

  • E-commerce information: Assessing purchase histories across different online platforms to spot irregularities.
  • Point-of-sale data: Analyzing transactions at physical retail outlets for discrepancies.

Communication data

Communication data encompasses information exchanged through various communication channels. Analyzing this data can reveal patterns indicative of fraudulent activities.

  • Email Metadata: Examining the structure and flow of email communications to identify abnormal patterns.
  • Call Records: Analyzing call data for inconsistencies that may indicate fraudulent activity.

Sensor and IoT data

Sensor and IoT data come from connected devices and sensors embedded in various environments. This data type helps verify physical presence and activity consistency.

  • Smart device outputs: Gathering data from connected devices to verify physical presence and activity consistency.
  • Wearable technology: Using data from fitness trackers and other wearable devices to cross-verify identities.
  • Internet of Things (IoT): Analyzing data from a network of connected devices to monitor and identify irregular patterns.

Digital interaction data

Digital interaction data involves tracking user interactions with digital platforms and applications. This data type helps identify unusual activity that might indicate fraud.

  • Web traffic and app usage: Monitoring website and app usage data to detect unusual activity, such as sudden spikes in traffic or abnormal usage patterns.

Public and third-party data

Public and third-party data come from external sources, such as government records and third-party databases. This data type helps verify user-provided information and assess risk.

  • Public Records: Leveraging government and regulatory data, including property records and court filings.
  • Employment and education history: Using background data for identity verification and risk assessment.
  • Jet tracking: Tracking and verifying private jet movements to detect inconsistencies that could indicate fraudulent claims or activities.

Examples of alternative data

To gain a more practical understanding of how alternative data can be applied, consider these specific examples. These cases illustrate how various types of alternative data can be leveraged to enhance fraud detection efforts:

Social Media activity:

  • Example: A financial institution cross-references social media activity with known user profiles to detect impersonation attempts. Unusual behaviour, such as sudden changes in friends list or unusual posting patterns, could trigger further investigation.

Geolocation data:

  • Example: A banking app uses geolocation data to ensure that a transaction made from an overseas location aligns with the user’s recent travel patterns. If a user’s account is accessed from Tokyo immediately after being used in New York, it raises a red flag for potential fraud.

Clickstream data:

  • Example: An e-commerce site analyzes users’ clickstream data to understand typical browsing and purchasing patterns. A sudden shift to bulk purchasing or erratic browsing could indicate a compromised account.

Social sentiment and product reviews:

  • Example: An online marketplace employs sentiment analysis on product reviews to detect fake reviews. A sudden influx of overly positive or negative reviews could signal a fraudulent campaign.

Satellite imagery:

  • Example: An insurance company uses satellite imagery to verify claims about property damages. Discrepancies between reported damages and satellite images can raise flags for potential fraud.

Email metadata:

  • Example: A cybersecurity firm examines email metadata to identify unusual communication patterns, such as sudden spikes in outbound emails or connections to suspicious IP addresses, which may indicate a phishing attempt or account takeover.

Smart device outputs:

  • Example: A home security company uses data from smart cameras and motion sensors to validate the identity and presence of occupants. Discrepancies in expected versus actual device usage patterns can flag potential intrusions.

Web traffic and app usage:

  • Example: A mobile app developer monitors app usage data to spot abnormal patterns, such as sudden spikes in usage from a single IP address, indicating possible automated fraud.

Public records:

  • Example: A loan provider cross-references a loan applicant’s claims with public records, such as property ownership or court filings. Inconsistencies between provided information and public data can indicate fraudulent intentions.

Employment and education history:

  • Example: During the hiring process, a corporation verifies a candidate’s employment and education history through third-party data sources. Discrepancies in listed versus verified employment periods could signal possible resume fraud.

Jet tracking:

  • Example: A luxury service provider uses jet tracking data to cross-verify the movements of private jets with client itineraries. Any inconsistencies in reported versus actual movements could indicate fraudulent behaviour.

These examples highlight the versatility and potential of alternative data in providing a more comprehensive, multi-dimensional approach to fraud detection. By integrating such diverse data sources, organizations can more accurately identify and thwart fraudulent activities before they escalate.
