Call State API for fraud prevention

Call state, location, device status and more APIs for the financial sector

Fraud detection and prevention

Service providers have new business opportunities to expose information from their network to prevent crime and help both their subscribers as well as financial institutions to prevent fraud and becoming victims of crime.

Overview

People increasingly rely on mobile connectivity for extended periods, often while engaging in other activities simultaneously. The network can provide detailed information about these connections and by correlating this data with other information, it is possible to detect and prevent fraudulent transactions in sectors such as banking, enhancing security and trust.

Challenge

In many cases people are encouraged to transfer money from their banking accounts by callers pretending to be someone else. Banks have difficulties to detect the fraud transactions. Additionally, in certain markets the legal systems hold the bank accountable, and banks may need to compensate any losses.

Solution

Service providers can expose the information about the connections, the connection start and stop time, the connection duration and the connection origin, this information can be correlated with other information to prohibit for example fraudulent transaction in the banking sector.

How it works

  1. A bank's IT system identifies a suspected fraudulent transaction.
  2. Transaction data, including the time, monetary sum and destination, are highlighted.
  3. The bank's IT system activates Ericsson's API with the victim's phone number given as a code.
  4. The telecom network responds with the data the API provides, including:
    • Call Status (if the device is in an ongoing call)
    • Call forwarding (if the call was diverted)
    • Device Status (if the device is roaming and is reachable)
    • Verify Location (if the device is in certain area)
    • SIM Swap (if recently the SIM has been swapped)
  5. Based on analysis of this information, the bank can now block the transaction, informing the customer to contact the bank if the transaction was legitimate.
Ericsson expert explains how APIs can be used in fraud prevention.

Business applications

The main target segment for this use case are the banks and financial companies. However, this could be applicable to other fraud detection and prevention use cases and segments.

Business models

Service providers can monetize based on three different models:

  1. Wholesale (towards the aggregator)
  2. Wholesale (towards the enterprise)
  3. Pay-per-use (towards the enterprise)
