Enter someone's address on Google, and now you can see a detailed picture of their house. Click here to see Google's picture of our headquarters (see screenshot below). You can zoom in and almost tell if there is valuable stuff easy to steal, or (if you are a nosy neighbor) look at the car and wonder if it's a client, a mistress, a nanny or whatever.
Police, detective, recruiters, your date and the government could also look at these pictures, in some automated and systematic way, or individually as cases present themselves. You could easily identify pot plantations, or the IRS could check whether your house or cars are worth repossessing - so there is some (arguable?) value in this data. Of course these are just static images and can be 5 years old, but maybe one day Google will be able to refresh the images every six months, or more frequently, allowing for better forensics.
Do you think this type of data should not be made available to the public? Should Google charge money to offer access to this data? Unlike your Facebook data (also used by stalkers, recruiters, burglars etc.), you did not opt-in to have a detailed picture of your house and car (and whatever else was there when the picture was taken) displayed to the entire world.
And if you were a burglar, wouldn't you use these pictures to pre-select neighborhoods and targets, and identify a larger number of easier, interesting targets without being recorded on a video camera?
