Menlo Park, Calif. -- Facebook said it has acquired San Francisco-based Face.com, developer of a facial recognition platform that identifies and tags individuals in social media photos. Though financial terms were not disclosed, TechCrunch pegged the price at $55-$60 million, citing a source familiar with the matter. "By working with Facebook directly, and joining their team, we'll have more opportunities to build amazing products that will be employed by consumers," wrote Face.com on its blog. Face.com's mobile facial recognition technology potentially could allow Menlo Park-based Facebook to begin offering automatic mobile photo tagging. The news comes two months after Facebook also acquired San Francisco's Instagram, developer of a popular photo-sharing app.
