When I think of Big Data and NoSQL I think of Big-Web-User companies like Amazon, Google, Twitter, Netflix, and other similar companies that amaze and entertain us by using the latest in NoSQL-based data science to bring us features that are useful and novel.  Mostly that means using recommenders, NLP, IoT, and advanced search algorithms to present just the right part of the their Big Data databases to us users.

There aren't many examples of more traditional companies, even information based companies that were being held back before NoSQL opened so many doors.  Most of those would have been in high-transaction financial services like Visa, or maybe some of the telecoms.  But recently I started thinking about other relatively 'traditional' businesses that have benefited from Big Data and the major credit / information / append data companies like Experian immediately came to mind.

In this excellent article, Bob Violino explains how Experian found business value in NoSQL and provides plenty of details if you'd like to learn about their roadmap.  As Bob says, "Some businesses look to big data to help them manage their information. Information service company Experian is looking to big data to help manage its business."

A very interesting a valuable story.  Read the rest here.

Detecting ID theft much sooner - when someone somehow managed to enter a fake phone number or fake address (in a state you never lived in) in your credit report - is still is its infancy. In my case, some criminals managed to create a fake ID under my name - I was supposedly a colonel in the US army - to obtain funds from a credit union that serves people in the military. All of this done online without basics ID checks. Then they typically try to open a bank account with an other institution to move money around before sending it abroad (money laundering). It looks like they were arrested in my case, but this could have been so easily avoided with better data science. After all, I'm not even a US citizen, so how could I be a colonel in the US army?

Smart criminals will actually ask Experian and other bureaus to put a fraud alert on your credit reports, but only after they succeeded in changing your address for good, so that you - the real guy - have no recourse, until, as always, the fraud is discovered and acknowledged - months later. Typical ID thefts results in above $30,000 gains for the criminal, per victim, and typically, above $1,000,000 in stolen money (across multiple victims) for the criminal. The victims do not really lose the money, the financial institutions do (although, since they actually electronically manufacture the money and get bailouts, this could be argued - the real loser could be the taxpayer or bank client paying higher fees to cover the losses, but definitely not the victim).
