Google will not be building a facial recognition search system, even though facial recognition technology is quickly advancing. According to The Telegraph, Google's executive chairman, Eric Schmidt, believes the "surprising accuracy" of facial recognition technology is "very concerning."

According to Schmidt, who spoke at Google's Big Tent conference in London, a database using facial recognition software is "unlikely" to be a service that Google will create. Schmidt did suggest that, while Google may not build a facial recognition search system, "some company, by the way, is going to cross that line."

That last comment may have been a subtle stab at Facebook, which recently started using facial recognition technology as a means of helping its users tag photos. I wouldn't be surprised, considering Facebook was recently caught attempting a smear campaign against Google.
