South Korean police have raided Google's offices in Seoul as part of their investigation into Google's unauthorized collection of unencrypted Wi-Fi data.
"We can confirm that the police have visited Google Korea in conjunction with their investigation around data collection by Street View cars," a Google spokeswoman said in an e-mail. "We will cooperate with the investigation and answer any questions they have."
Officials reportedly want to examine the data collected by Google.
"We will investigate Google Korea officials and scrutinize the data we confiscated today," the Cyber Terror Response Center of the Korean National Police Agency told The New York Times. "We intend to find out what kinds of data they have collected and how much."
In May, Google admitted that its Wi-Fi data collection devices, attached to the top of its Street View vehicles, had inadvertently been gathering data transferred over unencrypted Wi-Fi networks. Google temporarily grounded its Street View cars, and hired an outside firm to conduct a review of the data collection, which could not determine whether personal information was collected.
Google later said that the data was only accessed twice: when the individual engineer who designed the software first created it, and after the glitch was discovered and a security engineer tested the data to verify that this was the case.
In late July, data protection authorities in the U.K. said that they were satisfied that Google's Wi-Fi data collection did not include any meaningful personal data about residents in the region.
Google said recently that it agreed to hand over collected data to German, French and Spanish data protection authorities. Google has already destroyed data collected in Ireland, Denmark, and Austria.
Investigations continue in several countries, including Canada, Australia, and the U.S., where Connecticut Attorney General Richard Blumenthal is leading an investigation backed by 48 other state attorneys general.
