How to log all user interaction on my device?

I would like to know whether on an Android device it is possible to: 1. Log the date and time of every time a password is entered on my Android phone (this security measure would mean that if someone in my home sees me enter a password without me noticing it, and then uses it to log into my phone, I would then be able to see whether this happened or not to take care of my suspicion). 2. As an extra step, I would like to log all activity once the login screen is bypassed as well (for instance the date an time and application name for each time an application is opened. This is because, while my phone is password protected, once I make the screen go blank by pressing the hardware button on the right, some time goes by until a password is required: I have things set up this way so that I don't have to enter the password just so often). So, is there a way to log all user activity when the lock screen has been bypassed as well? The device I have is a Samsung Galaxy SIII Neo running Android KitKat 4.4.2. The device has been rooted. Thanks!!!
