Security & Privacy
This page describes the settings in the Security & Privacy application. The four tabs are as follows:
These settings specify whether a password is required when Ubuntu wakes fromor returns from a blank screen. Your computer will be more secure if in these cases passwords are required.
Files & Applications
These settings allow you to specify which recently-used files, folders and applications are listed in the Dash, and elsewhere.
In order to determine the recently-used files, folders and applications, Ubuntu collects usage data. If you wish, you can turn OFF collection of usage data and clear some or all of the collected usage data.
The Include: list lists some common file types. To include a file type in the usage data, tick the checkbox next to it. To exclude a file type from the usage data, clear the checkbox next to it.
The Exclude: list lists folders and applications excluded from the usage data. To add a folder or application to the list, click the "+" button and select the required folder or application. To remove a folder or application from the list, select it and click the "-" button.
