Google has released the full report of the Federal Communications Commission’s investigation into the company’s collection of "payload data" from millions of business and residential WiFi networks, says the Los Angeles Times. The FCC dropped the investigation earlier this month, after fining Google $25,000 for obstructing the investigation.

A more heavily redacted version of the report was released by the FCC on April 15. The new version released by Google to the LA Times, only redacts names of individuals, and reveals more details about how Google captured the data—and how much the company knew about what was being collected.

The data, which Google claims was stored "inadvertently," was collected over a two-year period by Google’s fleet of Street View cars along with photos and the location of WiFi access points. It included personal information from unencrypted wireless networks—captured network packets that included email messages, passwords, and website requests with attached cookie data that could be used to establish website usage history of the users of those networks.

In an email to the LA Times, Google spokeswoman Jill Hazelbaker said that the company "decided to voluntarily make the entire document available except for the names of individuals...While we disagree with some of the statements made in the document, we agree with the FCC's conclusion that we did not break the law. We hope that we can now put this matter behind us."

The FCC ceased its investigation after determining that the unencrypted network traffic wasn’t protected by federal wiretap laws, and a key Google witness invoked his Fifth Amendment rights. That witness was a Google engineer—referred to as "Engineer Doe" in the FCC report—that the company claims intentionally added code to the Street View data collection software to capture packets’ payload data. Google has declined to name the engineer.

But the FCC report called into question whether the collection of the data was as inadvertent as Google has claimed. Engineer Doe reportedly told two other Google engineers, including a senior manager, that he was collecting payload data as part of Street View. In October of 2006, he gave the entire Street View team a document detailing the work he had done, including the fact that payload data would be logged as part of the data collection.

On Thursday, Google’s attorney E. Ashton Johnson sent a letter to the FCC accepting the $25,000 fine—ending the investigation. But the company’s letter also blasted the FCC, claiming that the company hadn't done anything wrong, and that the FCC’s investigators had themselves obstructed the investigation by dragging their feet, and that the investigation would have ended much sooner if the company hadn’t voluntarily agreed to allow a seven-month extension. "This is hardly the act of a party stonewalling the investigation," Johnston wrote.
