Google Lets Wi-Fi Router Owners Opt Out [Broadband Reports]
In April of last year, it was revealed that Google was collecting Wi-Fi data from homes passed by their Google Street View cars. After the practice was discovered, Google claimed that it was only collecting SSIDs and wi-fi locations to improve its mapping and location finding products.
However, a company investigation later revealed that its Street View cars collected over 600 GB of data from networks around the world which included user names and passwords.
Recently, Google announced that they would be adding an opt-out for users to implement to ensure that their wi-fi data was not inadvertently collected by Street View cars. It's not exactly user friendly, however. In order to activate the opt-out and ensure your router is not included in Google's "Location Server Database" you have to change your wireless network name (SSID) so that it ends in "_nomap." In other words, a moderately sophisticted knowledge of routers is required.
