Facebook Inc. (Nasdaq: FB), owner of the world’s largest social-networking website, acquired Face.com, whose software products enable facial recognition in photos.

Terms weren’t disclosed. Face.com, based in Israel, helps users tag photos and find images of themselves online by recognizing facial features on social networks and photo-sharing sites.

Menlo Park, California-based Facebook already uses some of Face.com’s applications.

“People who use Facebook enjoy sharing photos and memories with their friends, and Face.com’s technology has helped to provide the best photo experience,’’ said Ashley Zandy, a Facebook spokeswoman, in an e-mailed statement. “This transaction simply brings a world-class team and a longtime technology vendor in house.”
