Upek, a provider of software technology that authenticates fingerprints for various security applications, has brought in $6.2 million of a targeted $12.7 million round or equity, rights and securities, according to a filing with the SEC. The Emeryville, Calif. company is backed by Diamondhead Ventures, Earlybird, EDBV Management, Green Dot Capital, and Sofinnova Ventures.

Upek filed to go public in 2007, but ended up withdrawing its application last year due to poor market conditions. It last raised funding in 2004, bringing in $20 million.
