SAN FRANCISCO – The Federal Communications Commission is probing Google Inc.’s collection of e-mails, passwords and other personal data through its Street View mapping service, the latest regulator to investigate the matter.

The gathering of data, done through equipment mounted on cars that take photos and gather other information for the company’s mapping service, has drawn widespread attention both in the U.S. and abroad. Google has said the data was captured via transmissions over wireless networks and was inadvertent.

Last month, the Federal Trade Commission concluded its own investigation of Google’s Street View data collection, declaring that the company had sufficiently revamped internal processes, including privacy training for employees.

On Wednesday, the chief of the FCC’s enforcement bureau, Michele Ellison, said that “as the agency charged with overseeing the public airwaves, we are committed to ensuring that the consumers affected by this breach of privacy receive a full and fair accounting.”

A Google representative did not immediately respond to a request for comment.

Google first acknowledged its collection of personal data via Street View cars in May. Last month, it reported that it had accidentally collected entire e-mails, Web addresses and even some passwords.

Google said it would delete the data as soon as possible, and apologized “for the fact that we collected it in the first place.”

The Electronic Privacy Information Center wrote to the FCC in May, urging the regulator to open an investigation. The group’s executive director, Marc Rotenberg, wrote that Google’s data collection may violate the federal “Wiretap Act.”
