The Android backup, means by which Google collects millions of keys WiFi

Did you know that Google has estimated that the passwords in virtually all WiFi access points in the world? Control that kind of information comes directly from Android, specifically the backup function by which the seeker has access to both the key to your home network as other private data. What is the problem?

Android has evolved a lot since the first version appeared official 1.5. Since then, the browser software implemented both optimizations, security patches and new features and tools. One of these is the data backup, an option that Google provides by default in the configuration process any Android terminal.

The Copy utility for the user

This automated feature collects some private data as a list of installed applications and their configuration, system settings, passwords and key WiFi connections recognized by the terminal. The real utility of this method is to facilitate user data migration from one terminal to another. Suppose we want to renew our smartphone. With just start the "tour" phone setup that appears only turn it on and keep alive the backup box, the new model will sync with Google servers. Thus, the terminal will store the data that we have allowed to copy, such as favorite pages, WiFi keys, passwords and other private data without having to re-enter them manually. Say the "personalization" of the previous model is transferred to another in minutes without user interference, a process that saves time usually the owner.

However, the usefulness of this service also has a downside, or at least I reported in ComputerWorld. And although the information is encrypted, the browser itself could read the data. It may seem absurd that Google recognizes the key to our home WiFi connection, passwords and social networking applications, but this situation becomes more evident when it comes to business. What happens when Google provides key access to a company network? The situation gets worse if we assess that the Mountain View may be forced to provide this information to the various governments and requesting authorities for various reasons.
How to avoid risking this kind of data? From ComputerWorld tell us how we can disable data backup. Thus, Google is not receiving our private data and stores them on their servers, so as to avoid situations like those described above, or even theft by cybercriminals. Moreover, disabling the backup of our Android tell Google to delete all information that might have been previously stored.
In terminals with Android Gingerbread to disable the option is in the menu, under Data Backup. In the case of Android Jelly Bean, the process does not differ much since we find the section under Backup and restore.
