Biometric solutions are changing the way we interact online, the way we pay for goods, the way we travel, bank, and authenticate our devices. But how secure are these solutions from the threat of a cyberattack? And how are the technology and data actually used? We take a holistic look at what we already know about biometrics – and ask, what’s next?

5 surprising facts about biometrics
Research into biometric technology and biometric systems is changing the way we identify and authenticate ourselves. We take a look at some of the most exciting developments in biometrics.
1. Fingerprint payments

One of the earliest biometric authentication methods, fingerprint recognition, has allowed us to verify our identity on our smartphones since the early 2010s. But in 2014, only around 19% of smartphones had the technology. In 2018, close to 70%.
Tech-wise, fingerprint authentication might seem like old news. But exciting innovations means that payment cards with a fingerprint reader are now being used for smooth contactless payments.
G+D carried out a pilot project with Crédit Agricole Touraine Poitou in 2019 to test biometric authentication payment cards, due to be launched on the market this year.
“Employing biometrics to authenticate to and use new digital services perfectly fulfils our customers and end-consumer expectations towards a healthy balance between convenience and a high security level,” says Dr. Michael Tagscherer, G+D CTO. “It will be a smart link between us and new digital services and their seamless applications.”
2. Multi-modal authentication
The basic design of the newest smartphones is about to change, and it’s on the back of the need for greater security and smoother authentication.
Modern devices use an advanced multi-modal biometric authentication method instead of relying on a single scan. By combining iris and face scans, maximum security is guaranteed.
Multi-modality is necessary because individual biometric sensors can be imprecise and can give incorrect authentication. If the sensor is set at highly sensitive, the real person could be rejected, invalidating the claim of a “seamless” process.
In addition, rather than using a small sensor on the front of the phone, identity verification in new devices can instead be done via an “under-display” authentication, with the sensor fully integrated into the display.
3. Palm vein recognition
As its name suggests, palm vein recognition, an increasingly popular biometric authentication method, verifies users by examining their vein pattern.
This creates an image of the palm, which is then used to verify a user for entry to a physical location or to log on to a computer or a network. As well as providing the same level of security as other biometric authentication procedures, the technology has the further advantage of being contactless, providing advantages in terms of hygiene.
4. Voice authentication
Speech recognition technology is what gave us Siri and Alexa. However, voice recognition is a different branch of biometrics – one that allows us to identify and authenticate by measuring the minutiae of sounds a user makes when speaking.
Developments in biometric authentication via voice, an emerging method, mean that nearly any internet connected device can double as a secure authenticator.
Voice biometrics identifies numerous voice patterns, including accent, speed of speech, the way users emphasize letters and words, and pronunciation. These verification systems can even identify physical characteristics, such as mouth and nasal passages.
5. Next-Gen biometrics
After passwords, fingerprints, face, vein, and voice recognition, what else is to come?
There are already many providers that offer authentication via keystroke dynamics, or type and wipe behavior on mobile devices; others can verify us by the unique shape of our ears or buttocks.
Perhaps most exciting of all is that next generation biometric authentication methods, such as EEG based brainwave scans and keystroke dynamics, are continuously expanding the horizons of secure authentication.
As the technology improves, devices will become even more portable and inexpensive to produce – and the potential for brainwave authentication becomes wider.
Together, these biometric authentication methods demonstrate how diverse and robust modern biometric authentication has become.
