As many as 67,000 phones are expected to get lost or stolen in London during the 2012 Olympics, which will hold its opening ceremony Friday.
With nearly 27,000 of those devices expected to be smartphones, the amount of data lost is expected to be as high as 214.4 terabytes. That's the equivalent of about 200 million books.
The estimate was released Monday by Venafi, an IT security provider, which based its calculations on the number of phones that get lost regularly in London and took into account the influx of people during the Olympics.
Normally, 50,000 phones are lost during every two-week period in England's capital city, and during the Olympics, the number of people in London is expected to increase by one-third. As a result, Venafi said it expects 17,000 more phones to be lost or stolen than normally are.
