Biometrics: Compelling Business Case, But Beware Hidden Risks – Part 1

This article is part of several items we have published that examine cybersecurity issues. Such security has become even more critical at a time when so many wealth management professionals work from home, a trend that has been going on for some time and accelerated by the pandemic.
Continuing our focus on the cybersecurity and data protection
challenges exacerbated by COVID-19, we now turn to the boom in
biometric authentication.
Part 1 of this feature unpicks the compelling business case for
verifying the identity of staff and clients using this
technology; Part 2 will dig deeper into the technological choices
and hidden risks wealth managers need to be aware of.
One potentially significant upside to the COVID-19 crisis is a
massive acceleration of the wealth management sector’s
digitisation - necessity being the mother of invention or, more
accurately here, adoption. Barriers are being swept away as
circumstances compel firms to implement solutions that many would
argue that they should already have in place. The impetuses
behind the rollout of enhanced performance reporting, client
communication portals, video conferencing and instant messaging
have suddenly become very strong indeed.
This is particularly true of biometric authentication, technology
which verifies an individual’s identity through biological or
behavioural characteristics. The concept may not be particularly
novel in financial services as over the years institutions have
variously implemented, or at least piloted, dactyloscopy
(fingerprint identification), face recognition, voice patterning,
iris/retina scans and even electrocardiograms to boost security.
What is new - technology vendors tell us - is the rocket-fuelled
take-up of this technology in the financial services sector, now
that business is being carried out almost exclusively in the
digital sphere, and outside institutions’ walls.
As this publication has recently explored, in itself the home
working environment may be far from ideal from a cybersecurity
and data protection perspective. At the same time, cybercriminals
have all too predictably moved to exploit the disruption by
massively ramping up their efforts to steal information and
identities. The pandemic has created an acute need to beef up
security to protect systems, devices and data. As a result, these
are boom times for biometrics across sectors, but particularly in
tightly regulated ones dealing with valuable and often very
sensitive data, as wealth managers most assuredly are (it may
often fall under the GDPR’s Article 9 definition of “special
category” data).
The weakest link
Single-factor authentication via a password or phrase has long
been regarded as antediluvian by security experts; at best, these
should only form part of Multi-Factor Authentication (MFA)
methodologies. “Brute force” attacks are easier than ever with
cracking technology, but it is well acknowledged that human
beings are the weakest link in the security chain. Even with
training, people are all too vulnerable to increasingly
sophisticated “social engineering” tricks like phishing emails
aimed at eliciting key information, along with other lapses like
writing verification details down. The sheer volume of what we
have to remember means the average internet user has to reset a
password almost once a week.
Nonetheless the scale - and escalation - of the problem may still
surprise. “Passwords are responsible for over 80 per cent of data
breaches, and there has been a 667 per cent increase in funded
cyberattacks on them since February,” notes James Stickland, CEO
of Veridium.
The costs arising from data breaches are several and serious.
Under the General Data Protection Regulation, supervisory
authorities are empowered to issue fines of up to €20 million or
4 per cent of annual global turnover for the most egregious data
protection breaches, but there is also provision for individuals
to seek redress through the courts for material and non-material
damage under Article 79. Reputational risk is naturally also
a huge concern in the private client space.
Password pain
However, what might not be so well recognised are the costs and
loss of productivity associated with resetting compromised (or
simply forgotten) passwords. As this cybersecurity feature
highlights, password expiration is another issue exacerbated by
the current dispersion of workers. “By ridding company processes
of passwords, businesses will not be so vulnerable to phishing
attacks, saving them the costs of a data breach," Stickland
explains. “But businesses can also save themselves millions of
pounds in costs associated with resets and increase productivity
across all departments.”
The seriousness with which financial institutions have to
approach security means that they have long favoured MFA, where
usernames and passwords are combined with a second or third
factor. Importantly, as Gerhard Oosthuizen, chief technology
officer at Entersekt, points out, strong authentication calls for
variety. “A combination of different types of authentication
factors is always stronger than using only one factor, or even
more than one factor of the same type,” he explains.
Familiar options to bolster “something you know” factors include
possession of devices such as cards and key fobs or
One-Time-Passcodes sent via “out of band” channels like email and
SMS (or, in their more modern form, generated by standalone
apps). However, to varying degrees these may be vulnerable to
theft or hacking, as well as adding unwanted friction to the
authentication process. For reasons of both convenience and
cybersecurity, the view of experts like Stickland is that “MFA
must move away from methods that verify what you have or know,
towards ones that verify who you are.”
Pushing on an open door
Wealth managers would be justified in thinking that they are
pushing on an open door here with clients, as most will be well
used to unlocking their smartphones with fingerprint or face
identification - as well as using biometric authentication for
mainstream banking apps. Indeed, many will have experienced
entirely digital onboarding for digital native services using a
combination of photo ID and selfies.
It could also be said that expectations (or at least hopes) of a
seamless digital experience apply equally to wealth management
personnel, who, already time-pressed, are now working under even
greater pressure. An aversion to clunky authentication procedures
will be particularly true for the born-digital generation of
advisors coming up, making eradicating them a matter of talent
management as well as productivity.
Answers in our hands
As with so much today, the answer may be literally in our hands
in the form of smartphones. And, verifying identities in this way
has several benefits beyond familiarity and the not
inconsiderable cool factor. As Darren James, technical lead at
Specops Software, explains: “Mobile device-based biometrics offer
three-factors rolled into one: the phone itself is the ‘something
you have’; a pin, the ‘something you know’; and your face or
finger is ‘something you are’. This is why financial institutions
like to use them so much for their mobile apps.”
The fact that staff and clients will invariably have biometrics
hardware already in their pockets is a further boon to the mobile
option, James continues: “Biometrics choices tend to depend on
what firms already have. Buying additional hardware, especially
if it’s for a single purpose, is usually cost prohibitive and a
barrier to adoption.”
By the same token, the need for speedy rollouts is a further
factor - wealth managers, like everyone else, having been bounced
into remote working with very little notice. As previously
explored, recent weeks will have seen very rapid evolutions (and
remediation) in everything from extending network security to
encompass home working, practicalities like providing privacy
filters for screens and updating IT and data protection
policies.
Beset by emerging risks, and under immense time pressure,
biometric authentication methods may seem heaven sent. However,
as will be explored next, there are also very serious risks that
wealth managers need to be aware of too.
