We have heard for a lot of time now that the next version(s) of Android will focus on being more secure than previous versions. This was talked about during Google I/O and has been seen in previous updates that address security and bug fixes. Google has recently said that the next major version of Android (L) will have data encryption turned on by default.
Encryption has been available on Android since at least the days of Honeycomb, but was hidden deep in the security settings. Yet, even though it’s been available, most users either don’t know how to enable it or simply don’t utilize the option. Starting with Android L, Google with enable encryption by default so you won’t have to dive deep into the settings menu. The Washington Post quotes Google spokeswoman Niki Christoff as follows:
As part of our next Android release, encryption will be enabled by default out of the box, so you won’t even have to think about turning it on.
Now, this is not necessarily something to be afraid of, as it simply keeps your devices secure from those prying eyes and hands trying to look at your data and content. It also prevents law enforcement from accessing data that would otherwise be handed over to them, even if they have a warrant or other type of legal documentation.
Google’s Android L security policy coincides with Apple’s iOS 8 counterpart in an apparent response to the Snowden leaks alleging NSA snooping. You’ll want to keep that encryption password handy, though (you’ll set it during the device setup process). Google will not have access to your device’s data as the password will only be stored on the device. While it protects your personal data even from search warrants, it also will leave you with no choice but to wipe your data and start all over again should you forget it.
