Abstract - In the rapidly evolving landscape of mobile technology, ensuring the security of personal and sensitive information is paramount. Continuous user authentication represents a significant advancement in mobile security, offeringongoingverificationofuseridentitybeyondtheinitial login. This paper explores the importance, methods, benefits, and challenges of continuous user authentication on mobile devices. It provides a comprehensive review of current technologies and research, highlighting the critical role continuous authentication plays in enhancing security and user experience in mobile ecosystems.
With the increasing reliance on mobile devices for a wide range of activities, from communication to banking, the security of these devices has become a major concern. Traditionalauthenticationmethods,suchaspasswordsand PINs, provide a one-time verification that can be easily compromised.Continuoususerauthentication(CUA)offersa dynamic and persistent security solution by continuously monitoringandverifyingtheuser'sidentitythroughoutthe device's usage session. This paper delves into the significance of CUA, examining its potential to mitigate securityrisksandenhanceuserconvenience.
