"My office will lead a multistate investigation -- expected to involve a significant number of states -- into Google's deeply disturbing invasion of personal privacy," Blumenthal said in a statement. "Street View cannot mean Complete View -- invading home and business computer networks and vacuuming up personal information and communications."
Over 30 states participated in a conference call about the status of Connecticut's investigation, but it's not immediately clear how many of those will participate in Blumenthal's inquiry.
Last month, Google revealed that it had inadvertently included experimental code that gathered unprotected WiFi network traffic in the software it used to capture images for its Street View service. The disclosure, which Google executives have apologized for and acknowledged as a screw-up, has prompted multiple lawsuits and Congressional scrutiny in the U.S. and widespread indignation in Europe.
Google has gathered Street View images in over 30 countries. Some countries have asked Google to delete the WiFi data it gathered while taking pictures; other countries have asked Google to retain the WiFi data to facilitate investigations.
Acknowledging its error, Google nonetheless maintains that it broke no U.S. laws. "It was a mistake for us to include code in our software that collected payload data, but we believe we didn't break any U.S. laws," said a company spokesperson in an e-mailed statement. "We’re working with the relevant authorities to answer their questions and concerns."
The statement by Blumenthal appears to anticipate the possibility that Google may not have violated any laws. "Our investigation will consider whether laws may have been broken and whether changes to state and federal statutes may be necessary," he said.
Last week, the French National Commission on Computing and Liberty (CNIL) released the findings of its Google Street View investigation in France. The group found that Google had captured e-mail account passwords as it grabbed data from unprotected WiFi networks.
A Google-translated version of CNIL's statement about its finding claims that Google "posted excerpts of content of electronic messages," but a Google spokesperson said this appears to be a bad translation because Google has not posted any captured e-mail content.
