A Secure Screen and App Lock System for Android Smart Phones Using Face Recognition

Mobile operating systems pervade our modern lives as we interact with these almost every day. Security and privacy are of particular concern on these systems, as they have access to a wide range of sensitive resources and can access private data. While just using the Settings app on iOS smart phones you can both secure the access to the screen and installed apps, in Android smart phones you can only lock the screen. For locking the apps, you must download a special application from a third-party store like Google Play. The objective of this paper is to emphasize the importance of having only one application which secures access to both the screen and the apps on Android operating systems using facial recognition. We created an application that can restrict the access to the installed apps in the system, control them remotely through a web platform and lock the screen. All of these ensure complete security, beginning from the screen, the main gateway that offers access to the phone, to the installed applications that may contain important information. Thus, using a single application, users can secure the entire phone without needing to use the phone settings.
