Privacy and security are always a concern when it comes to mobile devices, and many of us probably have something or other stored or installed that we’d like to protect and keep from prying eyes or curious children. This can take the form of a certain app or set of applications that you don’t want just anyone to be able to access, or even–dare I say it–some revealing photos that you no longer trust to the cloud. If that sounds at all familiar then fear not, there are a few ways you can help to maintain your security and privacy by restricting access to your device content.
XDA Forum Member 1tek has developed an application that does just this called Droid Protector. The app will allow you to lock individual applications as you see fit and protect them with one of three ways of unlocking: the classic PIN code, a calculator unlock, or the less secure but more intuitive pattern unlock. The application also allows you to decide which of the images or videos stored on the device are readily accessible. Any selected media is effectively invisible to anyone who happens to be using the device, but readily available to you by simply opening Droid Protector.
Another rather clever feature of this application is that it provides the option to disguise the fact that you have chosen to protect certain applications. This is achieved by not just simply refusing to allow access to the unauthorized user. Instead, the application will present them with a fake crash dialogue that in most cases shouldn’t raise too much suspicion with the average user, yet still allows you to protect and secure your privacy.
Droid Protector is available from the Droid Protector application thread right here on XDA or via the Play Store for free and is compatible with devices running Android 2.3 or above. Unfortunately, it is currently incompatible with the Android L Developer Preview although 1tek does state that he is looking to address that in the future.
