Google's Street View cars have been driving around roads all across the world capturing images of almost every single street but they had collected more than just navigational data. In fact, they had managed to grab information from private WiFi networks including emails and passwords. Though the information was 'fragmentary' Google say they wanted the data to 'improve its internal security and privacy practices'[Wall Street Journal]. But they now say that they will be deleting all information collected and that they are apologetic that the information was collected in the first place.
So wouldn't you be worried if you saw one of those vehicles travelling past your house and snapping away at your home and infiltrating into your WiFi networks as well? There has always been a privacy issue with Google Street View but I think its benefits have exceeded its costs. Despite all this controversy, at least Google was honest about their mistake and admitted readily to the authorities about it.
Thanks to their technology, travelling and navigating has become a lot easier..
