Nowadays, the usage of smartphones has expanded beyond simple phone calls and text messages, with people using them for online banking, shopping, video chats, and tracking their health. This necessitates the storage of private information on the device, and unauthorized access to this data can have catastrophic consequences. Therefore, safeguarding smartphones from falling into the wrong hands is of utmost importance. Researchers have developed various approaches to make sensor-based smartphone authentication simple for users by establishing clear requirements. However, many aspects of sensor-based smartphone authentication solutions still remain unexplored. In this context, the authors seek to investigate the current issues and concerns in the field of sensor based smartphone authentication through a comprehensive literature review. To achieve this, they utilized three digital scientific databases, namely ScienceDirect, IEEE Xplore, and Scopus. Potential studies were identified, and from a total of 450 papers, only 62 met the inclusion criteria. To help researchers understand the included research, a taxonomy was developed. In conclusion, this literature review provides a comprehensive overview of sensor-based smartphone authentication, highlighting its importance and potential to enhance smartphone security. The study identifies the current challenges and limitations in this field and suggests future directions for research. By addressing these issues, researchers can develop more effective sensor-based authentication solutions that are user friendly, secure, and privacy-preserving.
