Google starts to blur faces in StreetView Maps

After privacy complaints, Google Inc. is beginning to automatically blur faces of people captured in the street photos taken for its Internet map program. Rolling it out will take several months, however. Although Google's Street View service was not the first to augment online maps with photos, the detail and breadth of images on the site surprised and unsettled many users when it launched last year. As specially equipped Google vehicles cruised city streets snapping panoramic images of homes and businesses, the resulting photos revealed people falling off bikes, exiting strip joints, crossing the street, sunbathing everyday, in-public things but nonetheless, things they might not have wanted preserved for posterity.

Some privacy advocates, including the influential Electronic Frontier Foundation, suggested that Google blur the images of people. That move, the critics pointed out, would not inhibit Street View's goal of helping people become familiar with the look and feel of a location before they travel there. This week, Google revealed it had indeed begun deploying a facial-recognition algorithm that scans photos for mugs to blur. The changes are happening first in scenes in New York, before slowly expanding to the other 40 cities in Street View. Google spokesman Larry Yu said the company is still tweaking the system. For now it tends to err on the side of blurring too many things things a computer erroneously interprets as faces but that is better than leaving too many faces unblurred, Yu said.
