Abstract

Smartphones contain access to user-sensitive information such as contacts, e-mails, e-payments among others. Therefore, it is imperative that proper smartphone authentication tools guarantee that only the smartphone proprietary has full control of its mobile features and data. Following this, this paper proposes an overview of smartphone authentication, with the purpose to delve into two biometric viable solutions: Habitude Pattern Lock and ECG unlocking services. For that aim, it is required to provide a clear meaning about the different forms how authentication can be performed. As the next step, an introduction to biometrics is offered, which includes behavioral, hidden, and physiological approaches with the purpose of addressing their scopes and weaknesses. Then, to enrich the smartphone authentication environment, we propose the study of Pattern Lock and ECG verification tools. The Pattern Lock section discusses the study of topics like measure of pattern strength, commonly suffered attacks, and our proposal Habitude Pattern Lock, which includes the user habit patterns while drawing the lock pattern. Then, the ECG authentication section covers the features of this potentiality technology, ongoing research and products related to the ECG authentication on mobiles devices, and research topics like current limitations, specific acquisition concerns, and improvement proposals.
