1. A method of capturing notes on a mobile device, comprising:
displaying a lock screen on an electronic display of the mobile device and operating the mobile device in a write-only interaction state that provides write-only access to a secure file on the mobile device and that enables a user to enter information that is stored in the secure file;
rendering user inputs on top of the lock screen in a user input area and using the write-only access to store the user inputs in the secure file;
storing in the secure file the user inputs of the information that are received by the mobile device in the write-only interaction state; and
initiating user authentication operations in response to determining that a number of user inputs received and rendered on top of the lock screen satisfies a threshold amount.
