Juniper Research has named G&D (Giesecke & Devrient), Gemalto and Synaptics as leading disruptors within the rapidly expanding field of mobile biometric authentication, in a new report.The research firm's Biometric Platform Disruptors & Challengers Quadrant placed those companies as among those having the greatest capabilities to disrupt the wider mobile ecosystem through the implementation of their platforms.Juniper argued that while the biometrics sector itself is relatively mature, few deployments in the mobile space have achieved a critical mass of adoption, whether for use in payment or authentication.Juniper highlighted G&D's historic strength in the wider biometric space allied to an extensive breadth and depth of FIDO-certified solutions encompassing face, iris, voice and fingerprint technologies.According to Juniper, G&D – which is increasingly offering its solutions across the mobile environment – is well placed to exploit the burgeoning demand for biometric authentication.Research author Dr Windsor Holden said that, “With consumers increasingly willing to embrace biometrics as a more convenient alternative to passwords, players that can offer secure, user-friendly authentication platforms could contribute significantly to the evolution of the mobile payment space.”The Juniper Quadrant also recognised HYPR Corp as a 'Catalyst' within the field, arguing that as a first-mover in the biometric tokenisation space – and with a number of key clients already signed up – it was well placed to take advantage of enterprise interest in deployments.Other findings from the research include:• The value of all smartphone biometrically authenticated transactions is expected to increase from $14.2 billion in 2016 to nearly $655 billion in 2021;• Apple Pay currently accounts for more than 85% of these transactions.
