9to5Mac is pointing to a Norwegian Mac site called Mac1, which claims that Apple has bought all of the shares of Polar Rose, a facial recognition company based out of Sweden. The news is unconfirmed, at this point. 9to5Mac provides this Google Tranlsated excerpt:
Face.com, the developers of the facial recognition technology behind Facebook apps like Photo Tagger and Photo Finder announced that it is opening up its API, which will allow developers to take advantage of this technology anywhere on the web. We had a chat with Face.com founder Gil Hirsch, who talked about the technology, the API, Facebook’s Open Graph, and what kind of apps we can expect to see around this API.
