Google has opened the doors to one of its data centers to show how it protects customer data in this report from silicon.com.
A video released by Google on YouTube shows how it guards its data centers using a range of security measures - from biometric IDs for staff to the complete destruction of defunct hard drives.
Google's data centers handle information relating to everything from a search on Google.com to an e-commerce transaction through Google Checkout.
The security process starts with the design of Google's servers - with the machines custom-built to Google's specifications and running a specialized, stripped-down version of the Linux OS.
Google claims that the customized hardware and software limits the vulnerabilities of the machines.
