Callsign and CKH IOD Team Up to Enhance Fraud Detection

LONDON, [April 09, 2019] – Callsign, a London-based company at the forefront of the identity revolution, has joined forces with
CKH Innovations Opportunities Development (CKH IOD), a unit of CK Hutchison’s telecom division, to enhance fraud detection and prevention for the benefit of CK Hutchison’s 3 Group customers.

Three UK will be the first 3 Group operator, and the first mobile operator in the UK, to enable Callsign’s enhanced customer protection technology. 

The Callsign solution improves fraud mitigation by providing additional customer ID verification to banks, based on specific fraud risk triggers notified by Three UK. This can help protect customers from fraudsters who use fraudulent means, such as email or phishing scams, to obtain an individual’s personal data deceptively and use it to gain access to their phone number and bank account.

The combination of Callsign’s enhanced ID detection technology with Three UK’s customer insight means that it can help identify when a fraudster may have accessed a genuine mobile subscriber‘s phone number.

“We are committed to helping our customers who want to protect themselves from online fraud and enabling customer authentication and ID verification solutions that are secure for the individual and trusted by service providers” said Susan Buttsworth, CEO at CKH IOD. “Our partnership with Callsign will help improve SIM-swap and call-divert fraud detection for our customers.”

“For years now, I have been helping banks fight fraud, especially as they realise the fallibility of the password. As mobile banking has taken over, at Callsign we are increasingly working with the mobile industry to help them protect their customers from banking fraud,” said Ryan Gosling, Head of Partnerships at Callsign, who has deep experience working with both financial institutions and mobile operators. “By adding Three UK’s intelligence with Callsign’s intelligence, we can offer the most robust solution on the market”.
