Frictionless Authentication Systems: Emerging Trends, Research Challenges and Opportunities
It addresses the problem of balancing security and usability in authentication for consumers using mobile and wearable devices, but it is incremental as it reviews existing trends rather than proposing new solutions.
This paper reviews emerging trends and challenges in frictionless authentication systems, focusing on the need for secure, privacy-aware access across devices without obstacles, and identifies research opportunities related to user enrollment, usability, and security-privacy trade-offs.
Authentication and authorization are critical security layers to protect a wide range of online systems, services and content. However, the increased prevalence of wearable and mobile devices, the expectations of a frictionless experience and the diverse user environments will challenge the way users are authenticated. Consumers demand secure and privacy-aware access from any device, whenever and wherever they are, without any obstacles. This paper reviews emerging trends and challenges with frictionless authentication systems and identifies opportunities for further research related to the enrollment of users, the usability of authentication schemes, as well as security and privacy trade-offs of mobile and wearable continuous authentication systems.
