Authentication Engine

As organizations strive to deliver secure but seamless digital experiences, validating identity with data-driven, contextual authentication is the way forward. Callsign technology does exactly that.

What Data Means for Authentication

Authentication is all about stopping the bad guys from getting their hands on something of worth (usually money – and, more recently, valuable data) that doesn’t belong to them. Once upon a time, a hastily scribbled signature was considered an adequate means of authentication, but as the world has moved online, the need for more sophisticated methods of checking identity has emerged.

Over the last couple of decades, authentication methods have certainly matured. From PIN numbers to passwords to biometrics. From single-factor authentication to the more secure multi-factor authentication. Central to all of these is the end user, who is tasked with proving their identity via one or more authentication factors. The problem is that this often adds unnecessary friction when the user just wants to get on. In some cases, users can’t get on at all – as blanket authentication factors bring with them the risk of digital isolation.

When combined with our Intelligence and Policy engines, the Callsign Authentication Engine helps organizations strike the perfect balance between security and usability – reducing authentication steps by over 90%. Data and intelligence removes the need for intrusive or repetitive authentication steps, while authentication can be dynamically increased should the level of risk require it.

How the Authentication Engine Works

Callsign’s Authentication Engine is, of course, data-driven. Using the confidence score created by the Intelligence Engine, the Policy Engine tells it how to orchestrate authentication steps at every point of an interaction or transaction. It takes multi-factor authentication to seamless new heights and can adapt to any eventuality.

Multi-Factor Authentication

Increasingly, regulators require multi-factor authentication. This makes it harder for the bad guys to feign identity, so you can be doubly sure that someone is who they say they are. The Callsign platform delivers all typical authentication types, as well as some unique to us, using factors that span possession, knowledge and inherence. In other words, something you own (card or device), something you know (password or PIN), or something inherent (biometrics).

Real-Time Adaptability

It’s precisely because our identification solution is data-driven that it’s able to adapt dynamically, in real time, and respond to live challenges. This could be a perceived security threat, or simply that a user can’t authenticate via a particular factor, whether for demographic or practical reasons. If a user doesn’t have biometric functionality, for example, the Policy and Authentication Engines will deliver the next best factor in real time, without compromising security, ensuring no doors are closed for genuine users.
