CallSign partners with CK Hutchison to protect UK telecom customer from SIM swap fraud


CallSign has formed a partnership with CKH Innovations Opportunities Development (IOD) to enhance fraud detection and prevention by British telecoms.

CKH IOD is a unit of CK Hutchison’s telecom division, and will help integrate CallSign’s technology with CK Hutchison 3 Group companies, starting with Three UK, which will be the first mobile operator in the UK to leverage CallSign’s customer protection technology, according to the announcement. Three UK will leverage its own customer insight with CallSign’s ID detection technology to identify fraudulent calls made from a genuine subscriber’s compromised 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,” comments CKH IOD CEO Susan Buttsworth. “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,” says CallSign Head of Partnerships Ryan Gosling. “By adding Three UK’s intelligence with Callsign’s intelligence, we can offer the most robust solution on the market.”

BehavioSec argued last year that behavioral biometrics are “the last line of defence” against SIM swap attacks.
