Google could be sued for scooping up data from open wi-fi networks after a US court ruling.
A judge in San Francisco decided that the company's actions may have violated federal laws on wire tapping.
Google had tried to have the class action lawsuit thrown out, claiming that anyone could have intercepted the wireless signals.
It had previously admitted collecting the data by mistake while gathering images for its Street View service.
Since the blunder was revealed, Google has stopped its Street View cars logging wi-fi networks.
