The acquisition was rumored last month, but is now official. According to TechCrunch, Facebook will spend around $100 million on the purchase--roughly one tenth of what the company plans to spend on Instagram.
Face.com's technology can identify Facebook users' faces in photos or live video. The company already offers a Facebook app called Photo Tagger, which can identify faces and suggest photo tags, and also offers a standalone iPhone app called Klik that can identify friends in real time and adapt image filters to people's faces. Face.com also offers an API so other app developers can use the company's technology.
With the acquisition, Facebook will bring the Face.com team in house. The start-up says it plans to keep supporting third-party developers with its APIs.
Klik, an iPhone app by Face.com, identifies your Facebook friends in real time and lets users apply photo filters.
