The security firm said a total of 214TB of data will likely be lost during the games, which is equivalent to over 200 million books. Figures show that this year will see the largest-ever risk of corporate and personal data lost during an Olympic period.
Gregory Webb, Venafi Vice President of Marketing, said: "There's been an explosion of corporate data available to users from their mobile devices. This is a real danger and one that is often overlooked."
Venafi claims 50,000 mobile phones, such as the iPhone, are lost or stolen in the London area over any two-week period. An estimated 40 percent of mobile devices are now smartphones and the security firm has warned that the risk of data theft is particularly high.
It's worth noting that these recent figures don't even include numbers concerning other mobile devices, such as laptops and tablets.
Venafi has urged organisations to revise their data protection policies to protect customers further as the Olympics draw closer.
During the games, the capital's total population is expected to grow by a third, with an extra million people using the tube.
