Every time Apple releases a new iPhone, it usually corresponds with the release of an updated version of their mobile device-oriented operating system known as iOS.

Apple will usually show off some key features of the new operating system while demonstrating their newest phone to the press, but they tend to focus on the gee whiz features and might not always tell the public about all the great new security and privacy features that the new OS includes.

We've taken a look under the hood of the new iOS and found several security and privacy-related features that we thought you might want to know about. Here are 5 features that you will want to get to know:

1. Touch ID-Enabled (fingerprint reader) 3rd Party Apps

The much talked about Touch ID (fingerprint reader) on the iPhone 5S, 6, and 6 Plus, which could previously only be used to unlock your phone (under iOS 7) has now been opened up for use with 3rd-party apps. App developers such as 1Password, Scanner Pro, and others have already started incorporating Touch ID, adding a strong two-factor authentication mechanism to their apps.

This feature (if properly implemented) is a huge win for security conscious users.

2. Find My iPhone's "Send Last Location"

If you're like me, you misplace your phone a lot. The scariest moment you'll have as a phone owner is knowing that you've both misplaced your phone and that it's battery is likely dead so you won't be able to use Find My iPhone to have it make a sound so that you can locate it.

The new "Send Last Location" feature forces your iPhone to send it's last location to Apple when your battery gets down to a critical level. This can be useful in several situations as it will let you narrow your search for a lost phone to a smaller area, you can at least tell if you left it at home or at work. It could also potentially be used to help locate missing persons, as it will tell you where that person was right before their phone lost power (assuming you have their iCloud credentials or can obtain the information via the proper law enforcement procedures).

3. Notifications on Background App Use of Location Information

Is Facebook reporting your location information back to the mother ship when your not actively using the app? This answer to this question has both privacy and battery life implications. In iOS 8 you may start seeing pop-up messages that say something to the affect of "APP X has been using your location in the background, Do you want to continue allowing this?" followed by the option to "continue" or "don't allow."

You can restrict apps access to your location to "Never", "Always", or "While Using the App".

4. Enhanced Wi-Fi Privacy Using Randomized MAC addresses

So this one sounds a little security nerd-ish, but trust me, it's a step in the right direction. Previously Apple iOS devices made it easier for people to gather location data because each device had a specific MAC address that could aid in it's tracking by companies trying to track customers and "other people" who might also want to track someone.

According to information found on Mac Rumors, iOS 8 now responds to Wi-Fi scanning by providing "random" MAC addresses which should help prevent tracking of unique iDevices by folks who track that sort of thing.

5. More Types of Personal Data Encrypted By Default

According to Apple, the new iOS 8 encrypts many more types of files than previous versions. This helps to enhance data privacy and should (in theory) help prevents law enforcement from being able to circumvent the security of your device to get at those documents.
