Top Trends for Biometrics in Financial Services

Biometrics is certainly a technology that is rapidly being adopted by the Financial Services industry and this is not just confined to mobile deployments. Mobile is a growing channel for the delivery of financial services and will start to dominate most financial sectors over the next five years but other channels are still a vital part of any delivery strategy.

This is an important message that I have learnt after spending the second half of 2015 researching how biometrics is becoming an important tool within the security toolbox that can be utilised in the fight against financial fraud and identity theft.

In a series of analyst reports that I authored in 2015 that were published in June, October and December 2015 by Goode Intelligence, I was able to carry out a deep-dive  into the adoption of biometric technology in financial services. This included banking, payment and mobile-based biometric services.

In the reports I identified five key trends that are currently shaping this market.

Bye Bye PINs for ATM Security

ATMs are unattended and when I type in my PIN I am always uber-aware of who is standing behind me in case they may be attempting to steal my PIN. Being a paranoid sort of person I go through a series of checks that includes checking for ATM skimmers or evidence that a camera may be pointing at the keyboard. Banks have installed awareness notices and stuck-on mirrors to help me protect my PIN but it shouldn't have to be like this. 

Things are changing and banks are modifying their ATM technology to phase out PINs and to embrace biometrics. There is also choice in the biometric deployment method; a bank can either integrate a biometric sensor into the ATM itself (fingerprint, palm-vein, finger-vein and Iris are being used) to go either cardless (my biometric replaces the plastic) or keep the card (the biometric is stored on the card and a biometric is captured at the ATM and then matched against the stored template on the card). There is also a mobile biometric solution that also replaces the need for a plastic bank card or integration of specialist sensors at the ATM; Hoyos Labs has a neat solution where the mobile device interacts with an ATM using a combination of barcode and mobile biometric authentication technology.  And if you like plastic cards then there are solutions as well; a number of vendors, including Zwipe, have integrated a fingerprint sensor into plastic cards to replace PINs. The plastic bank card will only work if the authorised user's fingerprint is first placed on the sensor. 

Authenticated Contactless Mobile Payments

One of the more visible success stories for biometric adoption in financial services has been the development of mobile biometric contactless payments. Apple Pay and Samsung Pay both use integrated fingerprint sensors to secure contactless mobile payments in physical locations. The PIN was adding friction to the physical payment experience so you can either forget about user authentication and limit the transaction amount (tap and pay for low value payments) or replace the PIN with a method that doesn't slow down the experience but still adds a level of security. 

How to tackle rising levels of Card-Not-Present Fraud?

Technology does reduce fraud. The deployment of EMV chip cards has led to a reduction of fraud at the physical point of sale. This has led criminals to move online and attack commerce channels that the EMV chip cannot protect. The rise of Card-Not-Present (CNP) fraud, especially for eCommerce transactions, and the movement towards mobile commerce has created the need for secure and convenient user authentication and transaction verification. Biometrics offers a viable solution. Expect to see the payment networks start to roll-out mobile-based biometric solutions that aims to tackle the CNP fraud problem and even support in 3D Secure 2.0. 

Wearable Payments to support Biometric Authentication 

It is early days for wearables; the market is too fragmented and there are too few devices currently being used by consumers. This will change and as more and more apps are developed to support the delivery of financial services to bands and smart watches then the need to validate identity and to protect commerce will become critical. For wearables, it is important to pick a biometric modality that suits the device and the application so expect to see technology such as heart-rate (ECG), behavioral and vascular being integrated into the next generation of wearable devices. Biometrics that can be captured when a device is close to the skin of its wearer. Brainwave for Glass perhaps?

Financial-Grade multi-modal biometric authentication to become de-facto for mobile banking apps

The final trend that I am pulling out of these reports is part of a movement to increase security of mobile-based biometric solutions without adversely effecting convenience and ensuring that financial services providers maintain ownership of identity. The industry needs to ensure that the biometric technology is hard to spoof, that the protocols cannot be compromised and that the vulnerabilities seen in existing 2FA solutions (including replay and man-in-the-middle attacks) are not introduced. And at the same time being easy to use, scalable and fit into existing identity lifecycle management tools (can I revoke a credential?). The use of more than one biometric modality, face and voice for instance, in a banking app can increase security and also provide choice for consumers. A service provider can also match the right biometric modality to the context of the login or transaction attempt; fingerprint may open the app but a challenge using another modality may be needed to send a payment to a new beneficiary. 

To conclude; both established financial services organisations, challenger banks and the emerging FinTech providers now understand the importance of choosing the most appropriate user authentication and transaction verification technology that can work across all finance channels and can meet the needs of convenience and security. Biometrics certainly ticks the boxes for convenience with millions of customers around the world paying for products and accessing mobile banking with the touch of the finger or by taking a selfie. A number of biometric platforms are also being introduced that also tick security, regulatory and privacy boxes including IEEE's Biometric Open Protocol Standard (BOPS). 

What is exceptional about this market is the sheer scale of deployment that has already taken place and the enormous potential that is yet to come. From millions of Brazilians daily withdrawing cash from biometrically-enabled ATMs, to mobile banking customers accessing their accounts with the touch of a finger or by taking an image of their face, the use of biometrics for financial services is improving security, reducing financial fraud and removing the need for cumbersome authentication solutions that are not fit for purpose in today's hyper-connected world.

Innovation in Biometrics Enables Alternative Payment Methods

Payments have been the major driving force for the wide-scale adoption of biometrics in the consumer market. Today, millions of customers (Goode Intelligence forecast 350 million plus during 2015) are using biometrics on a daily basis around the world to provide secure convenient user authentication and transaction authorisation and this theme is set to continue with a forecast of over three billion users by 2020. 

Biometrics for payments is increasingly a vital part of a payment service providers’ toolkit in the never-ending task of reducing financial fraud and ensuring that their customers can conveniently prove their identity and authorise transactions.

The adoption of biometrics for payments is also leading to wide-scale disruption in the payment industry, enabling alternative methods for consumers to pay for goods and services in a variety of payment scenarios. This is not simple replacing one authentication mechanism with another; the finger replacing the PIN. Biometrics is allowing alternative payment methods to be introduced, some of which are being supplied by non-traditional payment service providers. 

HYPR Corp has developed a biometric security protocol that provides digital payment platforms, including Bitcoin, with a solution to secure access to their digital payment assets.

One of the core security concerns around Bitcoin and other digital currency platforms is that unlike with credit cards, transactions are irreversible.

HYPR was founded to solve the core fraud problem by providing a definitive answer to the question of “Am I who I say I am?” 

HYPR answers the question of “Am I who I say I am?” through a three-factor authentication protocol that creates a biometric authentication bridge between the user and their mobile wallet. The cryptographic algorithm that HYPR uses is the same as the digital signature algorithm that the Bitcoin protocol uses. Because of this similarity, future iterations of the HYPR biometric security platform could be used to biometrically validate Bitcoin transactions.

Another company looking to secure Bitcoin transactions is Nymi with their heartbeat-enabled wearable band. The Nymi band can be used to store a users Bitcoin in a native biometric wallet with the private key tied to a unique ECG biometric signature. I recently demoed the capabilities of the Nymi band at a presentation I gave on the future of biometrics for wearables at the Biometrics 2015 conference in London. I even use the Nymi band to log me into my office computer and have been impressed at how natural it feels to allow me access to my computer. 

It is also enabling new ways in which consumers can use traditional payment methods, even cash (still the preferred payment type for many people). Hoyos Labs has developed a smartphone-based biometric authentication solution that aims to reduce the increasing amount of fraud at the ATM, negating the problem of bank card skimming. Their 1U ATM product is a software platform that allows bank customers to access their accounts via ATMs using biometrics on smartphones. There is no need for cards or for the customer to enter in a PIN at the ATM as the entire authentication occurs on the customer’s smartphone.

The Hoyos Labs solution is compatible with existing ATM platforms and does not need any hardware to be installed on the ATMs.

These are just three examples of how the latest biometric solutions are protecting payments and enabling alternative ways in which we can pay for a wide range of goods and services in a variety of payment scenarios; from Bitcoin to the humble bank note

I explore many more examples of biometric payments, including the rise of the mobile wallet, in an analyst report recently published by Goode Intelligence; "Biometrics for Payments; Payment Security Gets Personal". 

 

A guide for banks in choosing the most appropriate biometric system

Banks are racing ahead in deploying biometric systems in an attempt to control rising levels of financial fraud and to reduce friction on inconvenient forms of authentication and fraud management. 

There are many different competing biometric modalities that banks can implement but what criteria do (or should) they use to ensure that the biometric system is appropriate.

Through Goode Intelligence, I have been involved in a number of consultancy engagements with banks and suppliers to assist them in assessing and choosing the most appropriate biometric system to meet their requirements.

Based on this experience, and engagements with a wide range of biometric and authentication technology companies, we have devised an assessment methodology that banks and systems integrators can use to ensure that the most appropriate biometric system is chosen. 

The Goode Intelligence Banking Biometric System Assessment (BBSA) tool is based on four interlocking parts, biometric performance, usability, regulation and security. It is also applicable to other highly regulated industries including healthcare, government, telecommunications and utilities. 

The methodology provides guidance to banks in assessing biometric systems and exactly how a bank weights the assessment criteria is dependent on their own set of circumstances such as budget, security policy, bank channel, regulatory environment and risk and privacy models.

There will obviously be other technical and non-technical assessment criteria that a bank will use including integration, scalability and support models etc. 

Biometric Performance: The assessment of the biometric performance and accuracy of a banking biometric system includes measurement of False Reject Rates (FRR), False Acceptance Rates (FAR) and Failure to Enrol Rates (FER). The accuracy of a banking biometric system is expressed as an Equal Error Rate (ERR). It is important to be pragmatic when assessing biometric systems using these standard biometric performance measurements as 'lab conditions' may not match those experienced by a banks' customers when they are using the technology. It is important for a bank to ensure that they can continuously measure the performance of a live  biometric system and banks must ensure that their suppliers can meet this requirement.

Usability: Today’s app-driven world means that getting usability right across a wide-range of devices is essential. What might be an appropriate biometric modality in terms of usability at an ATM might not be appropriate when a bank customer is authenticating themselves via a mobile app or via an Interactive Voice Response (IVR) solution. A pilot or proof-of-concept (POC) provides an opportunity for banks to evaluate a biometric system and different biometric modalities. Financial institutions should build usability measurement into these pilots and POCs and to gather feedback from users in reference to how easy the biometric systems are to use. Regional differences also play an important part in the usability choices of a bank; a biometric system that is suitable for one region may be inappropriate for others.

Security: When evaluating a biometric system for banking, banks should ask whether the system is secure and able to meet internal and external (regulatory) security requirements. Biometric systems must adhere to security policy and regulation and biometric data, including templates, should be securely captured, encrypted and stored. 

Regulation: Banking (industry) regulation is the fourth main component of the assessment of a biometric system for bank use. Biometric systems in banking is currently controlled by a mixture of data protection and privacy regulation, such as the EU’s Data Protection legislation, technology-based guidelines including the US’s FFIEC guidance on the use of authentication in an internet environment, and specific financial services regulation including the EU’s Payment Services Directive II (EU PSD II).
