Google allows Android users to automatically backup their essential app information in addition to settings to their Google account, allowing them to but restore it when required, instead of re-configuring all the apps afterwards formatting or switching to a novel phone.
However, until straight off your backup information was non encrypted in addition to visible to Google, in addition to straight off the society is going to modify its storage procedure.
Starting amongst Android Pie, Google is going to encrypt your Android device backup information inwards the next way:
Step 1: Your Android device volition generate a random hole-and-corner primal (not known to Google),
Step 2: The hole-and-corner primal volition in addition to then larn encrypted using your lockscreen PIN/pattern/passcode (not known to Google),
Step 3: This passcode-protected hole-and-corner primal volition in addition to then securely sent to a Titan safety chip on Google's servers,
So, your Android dorsum information volition larn encrypted or decrypted solely if the lockscreen passcode larn authorized through the Titan safety chip.
"The Titan flake is configured to solely unloose the backup decryption primal when presented amongst a right claim derived from the user's passcode," Google writes.
In other words, the Titan safety primal volition non decrypt whatsoever of your backup information unless it detects the lockscreen passcode you lot accept used to asking for decryption.
To foreclose creature forcefulness attacks, Google's Titan flake volition permanently block access to the backup information if somebody inputs wrong passcode combinations several times inwards an essay to jurist it.
"The express number of wrong attempts is strictly enforced past times a custom Titan firmware that cannot last updated without erasing the contents of the chip," Google says.
"By design, this agency that no ane (including Google) tin access a user's backed-up application information without specifically knowing their passcode."
Google likewise hired cybersecurity in addition to conduct chances mitigation theater NCC Group to perform a total safety audit of the novel Android Cloud Backup/Restore feature. NCC discovered a few issues, which were chop-chop fixed past times the company.
Google has non silent confirmed that which Android smartphones volition last able to role this additional layer of security, but it is clear that the device must last running the latest Android ix Pie operating system.
