UnionDigital Bank chooses the Callsign platform to provide passive multi-factor authentication to protect against account takeover

Singapore - 2 Nov 2022 - Callsign, the digital trust pioneer, announced today that UnionDigital Bank, the digital banking subsidiary of Union Bank of Philippines, has chosen the Callsign platform to protect consumers against scams and fraud including account takeover (ATO) by providing passive multi-factor authentication for customers using the new digital banking service.

“Innovation is at the core of everything we do at UnionDigital Bank. It is our priority to ensure that we get the best tech out there to ensure that we provide optimum experience to our customers as they maximize their power to access financial services that they deserve, safely and securely,” said Dominic Grunden, Chief Information and Security Officer, UnionDigital Bank.

“With Callsign on our side, we are confident that we can do our part in eliminating fraud to build a better and safe digital economy for everyone. Callsign’s solutions have given us unrivaled intelligence across device and consumer behavior to accurately identify our genuine users, allowing us to tailor user journeys, contributing to an exceptional user experience,” Grunden added.

Callsign’s technologies deliver UnionDigital Bank customers an easy and frictionless authentication experience to access their bank accounts through the mobile app and web. Designed for the digital world, Callsign’s passive authenticators such as behavior PIN and path allow multi-factor authentication, an interaction that is unlike any analog methods, such as username, passwords and OTPs, which all add unnecessary friction.

UnionDigital Bank is using Callsign’s behavioral biometric technology to analyze unique human characteristics such as the way the user types, interacts and holds their device with device fingerprinting which creates a precise, unique profile of a device from which “genuine” devices can be identified.

UnionDigital Bank has also deployed Callsign’s Bot detection which estimates whether attempts to access a service is likely to be generated by automation or a real human. Bringing this all together, UnionDigital Bank has implemented Callsign’s Intelligence Engine to analyze behavioral and intelligence datapoints to ascertain if a genuine user is accessing an account.

If any intelligence is unusual, UnionDigital Bank can quickly adapt the authentication journey in Callsign’s Orchestration Engine where rule-based policies can be managed in real-time with no code changes. This allows UnionDigital Bank to adapt to the fast-changing needs of their customer base.

Critically for UnionDigital Bank, unlike static biometrics, Callsign obfuscates the behavioral biometric data meaning that the authentication experience is completely privacy preserving for UnionDigital customers.

‘At Callsign we continue to lead the market with technology that passively and positively identifies genuine users across all digital channels. This approach benefits consumers with less friction and more personalised user experiences. UnionDigital Bank recognizes the possibilities of this technology, and we are delighted to be working with them,’ concluded Namrata Jolly, General Manager, Asia Pacific, Callsign.
