Hidden Eye works in the following way. If someone trying to unlock your phone with wrong password many times, your device’s front facing camera will take a picture of him or her. This photo is stored on the device, so that you can identify who was the perpetrator.
In addition, there is an option to synchronize it your Dropbox account. All the captured images will be synced with your Dropbox account. So you can see who is the real perpetrator from anywhere on any device. If your phone has no front facing camera, the application can still help you when someone try to snoop into your phone. You can set the phone to sound your default ringtone if someone is trying to unlock your phone with wrong password. The application works with almost all android devices and can be downloaded from Google Play Store. [Via]
