Mark Zuckerberg is a pretty big deal.
Lord of Facebook, Emperor of WhatsApp, King of Instagram, we can only begin to imagine the sort of ransom demands that could be levelled at him if any hackers got into his personals. His internet empire took something of a knock just last month when someone managed to blunder into his Twitter account with an old password.
You can understand if he's a touch paranoid about security then. Paranoid enough to do this...
This is the image his Zuckerness posted on Facebook to celebrate the fact that 500 million people now use Instagram - some 300 million a day.
There are no muscular security guards, no tin foil hats or drone patrols. You have to do a bit of zooming if you're going to spot it...
Why? To stop anyone who might have managed to slide some sinister software into Zuckerberg's laptop from being able to remotely access either camera or microphone without him knowing it. It might sound like a fairly low-key security measure, but it's a simple step that hackers can't get around, no matter how advanced their software is.
Sure, it looks pretty paranoid. But given the man has been hacked, we can understand why he'd take every available step to ensure no one can overhear a discussion of some top secret Facebook plans, or idol mutterings as he types in his new password.
Smart move Zuckerberg. Smart move.
