Finsphere, a company that uses mobile phone location data to authenticate a consumer’s identity, announced $1.8 million in new funding last week. The new round is internal, with an additional contribution from an unnamed investor. Its funding now totals $33 million.

More notably, the Bellevue-based company partnered with Visa to offer what the credit card company is calling Mobile Location Confirmation. Visa will use Finsphere to ensure the GPS location of the customer’s smartphone matches the location their credit card is swiped. This helps eliminate unnecessary purchase declines, while ensuring the purchase isn’t fraudulent.

In a dovetail announcement this week, Finsphere also reported that it will bring retail banking executive Deanna Oppenheimer on board as a strategic advisor.

Finsphere demonstrated its identity security service at FinovateEurope 2012.
