The Commonwealth Bank (CBA) and Telstra have announced a new pilot to help protect their customers from phone scams.

Scam Indicator, currently in proof-of-concept stage and to be piloted over the next few months, will help protect joint CBA and Telstra customers from phone scams where criminals try and trick people into transferring them large amounts of money.

Early results of simulations suggest the prospect of improvements in the detection and prevention of scams, potentially mitigating customer losses of up to $15-20 million.

The tool is designed to detect certain high-risk scam situations in real time using a Telstra API that CBA will call on as part of its scam detection processes. This enables CBA to check if a customer is on a phone call – the prime indicator that a scam is occurring. This allows CBA the opportunity to try to contact the customer or put in additional checks. To protect the privacy of both parties, CBA is only able to access specific data points relating to scam prevention through the API, and does not have access to any other underlying customer data.

Vicki Brady, Telstra CEO said Telstra had taken an industry lead in protecting its customers from scams and other malicious activity through its Cleaner Pipes program, and the Scam Indicator was another example of how data and AI could be used to deliver positive outcomes for customers.

AI is a key part of Telstra’s T25 strategy and is used internally across its customer service function to help improve product recommendations and across networks to help identify potential issues and cyber threats.

Last year, Telstra launched Quantium Telstra, a new joint venture dedicated to creating AI solutions with the customer at the centre. Quantium Telstra has been instrumental in conceiving, developing and deploying the proof-of-concept for Scam Indicator in close consultation with CBA.

The Scam Indicator is the latest initiative in both organisations’ deep commitment to tackling scams.

The latest initiatives build on a suite of recent announcements from CommBank aimed at helping to protect customers from scams, including NameCheck technology for money transfers and new caller verification via the CommBank app, as well as a national campaign to raise awareness and help Australians to take steps to protect themselves from scams.

Following further testing, the Scam Indicator is expected to be made available by CBA to joint CBA and Telstra customers later this year.
