Efforts to convince the average user to implant or swallow a piece of technology to increase security are more likely to erode trust in new authentication innovation, according to a cybersecurity expert at global financial firm KPMG.Matt White, senior manager in KPMG's cyber security practice, said that biometrics will improve security over simply having just passwords, but that companies need to invest in user awareness and training.”The largest hurdle with biometrics going forward will be the establishment of consumer trust,” he said. “Passwords have been around for so long that they are an integral and accepted part of user transactions. Replacing passwords with biometric alternatives such as fingerprints provides better security, however it doesn't completely eliminate the risk posed by cyber criminals.”White's comments just a week after Paypal global head of developer advocacy, Jonathan LeBlanc, outlined in a presentation a range of 'next generation' authentication solutions, including vein recognition, ingestible technology and computer chip tattoos.LeBlanc's vision is that health measurements such as ECG, glucose levels or other internal features could be treated as unique identifiers for authentication.
