How Biometric Technology will Transform Mobile Security

Smartphone data security is growing in importance as more people are storing and accessing personal, business and financial data on their devices. Alphanumeric passwords are the common method of authentication, but can be difficult to enter accurately while on the move.

Furthermore, the small screen size on smartphones -- relative to that of a desktop or notebook computer -- means that password input is more difficult, while an accidental keystroke can increase the user frustration.

That said, biometric authentication is able to move beyond fingerprint scans and include a range of identifiers, from facial recognition to voiceprints, according to the latest worldwide market study by Juniper Research.

Biometric Technology Market Development

These methods will become part of many more consumer lives, installed on an estimated 190 million mobile devices  in 2016 -- including smartphones and wearables -- before exceeding 600 million devices by 2021.

The new research found that demand from businesses for methods that rely less on hardware will raise the profile of newer biometrics over the next 5 years -- in particular, voiceprints and facial recognition technologies.

These advanced technologies are easier to deploy than fingerprinting, as they do not require dedicated hardware. They introduce biometric security to a whole new audience in markets with lower-tier smartphones.


With many different biometric technologies now emerging for consumer use, Juniper predicts that multiple biometric apps will become part of consumer mobile experience in the near future.

The market study also found that use cases for biometrics will shift from identification to verification, thanks to the need for increased security of the biometric itself.

In these cases the biometric is stored and approved on-device and an affirmation sent to a service, rather than the biometric being transmitted and compared to a remotely held record.

This is because biometrics cannot be changed like passwords, and so if they are compromised, they are unusable for life.

Outlook for Biometric Technology Adoption

"While biometrics offer an increased amount of security and convenience, they need higher levels of protection," said James Moar, senior analyst at Juniper Research.

According to the Juniper assessment, establishing best practices for storage and transmission of newer biometrics will be key to ensuring both user control over and the security of the most personal stored data.

Trillion-Dollar Smart Power Grid Transformation

The global energy landscape is undergoing a significant transformation. Renewable energy sources like solar and wind are rapidly gaining ground as we transition towards net-zero emissions. However, this transition hinges on a crucial but often overlooked factor: the modernization and expansion of our aging power grids across the globe. For decades the backbone of our electricity delivery system has been largely static. The influx of variable renewable energy sources like solar and wind presents a new challenge. Smart Power Grid Market Development Integrating these resources effectively requires a Smarter, more Responsive grid that can handle fluctuating power generation and efficiently distribute it across vast distances. This is where a new trillion-dollar energy market growth opportunity emerges. According to a recent worldwide market study by ABI Research, global investments in public grid digitalization and transmission network expansion must exceed $4 trillion by 2030 to meet our
