At Yankee Group, we’ve been researching and predicting the future for a while now. Sometimes we get it right, and sometimes not so much. Our biggest Big Bet is the one we’re making around Anywhere — the notion that the global connectivity revolution will introduce dramatic changes in the way we live and work.

A key part of our Big Bet is around something very tiny. Made from plastic and glass and silicon, mobile phones are getting smarter every day. Even better, the increase in flat-rate data plans means that the mobile internet usage is going to explode. This broad macro trend — increased mobile internet usage — has profound implications for security, and in particular for mobile identity. If you take your phone, keys and credit cards with you, it seems to me that you will want to take your identity along too.

With that background in mind, I’m pleased to give YG blog readers a quick preview of a report I just finished today called Sizing the Mobile Identity Opportunity that puts numbers around how big mobile identity might be. Based on a model derived from our consumer data and mobile forecasts, the numbers, which I believe are conservative, are eye-popping. Assuming our forecasted mobile usage trends continue as we expect, by 2012 US mobile subscribers could generate over 360 billion identity events per year. By “identity event,”  I mean the act of authenticating to an online service or website. Applying the Law of Large Numbers to a miniscule fee per event yields another big number in the hundreds of millions of dollars. These are dollars that mobile operators and identity management vendors could leave on the table unless they capitalize on the opportunity.

This report won’t be available for several weeks. It usually takes a little while for our Editorial services group to bang out the dings in my dented prose, and for our peer reviewers (which in this case will include several outside organizations) to weigh in. More about this soon!
