Facebook has agreed to acquire facial recognition technology company Face.com, according to a post on Face.com.

The Israeli company builds facial recognition software for web and mobile applications, which can identify and tag people in a photo or help users discover photos of themselves they didn’t know were online. TechCrunch reports that the acquisition price was around $100 million.

Facebook has used face recognition to suggest photo tags on its desktop site since 2010. Its latest mobile camera app doesn’t include this feature, but following the acquisition, it could do something similar to Face.com’s Klik app. Klik uses face recognition to let users tag their friends in real time. It also allows users to apply and adjust photo filters based on faces found in an image.

Face.com founder and CEO Gil Hirsch suggested in his blog post that his team would be focused on mobile when it joins the social network company.

“We love building products, and like our friends at Facebook, we think that mobile is a critical part of people’s lives as they both create and consume content, and share content with their social graph,” Hirsch wrote. “By working with Facebook directly, and joining their team, we’ll have more opportunities to build amazing products that will be employed by consumers – that’s all we’ve ever wanted to do.”

Face.com says it will continue to support the developer community that uses its APIs, though it did not say what would happen to its own apps like Klik.

Rumors of Facebook acquiring Face.com began in 2011 and resurfaced last month. The company, which was founded in 2007, has about 14 employees, according to LinkedIn. It has raised a total of $5.3 million from Yandex and Rhodium.
