A pair of security researchers today announced that they are sounding the privacy warning bell about the capability of iOS 4 to track the location of an iPhone or iPad on an ongoing basis, storing the data to a hidden file known as 'consolidated.db' in the form of latitude and longitude and a timestamp for each point.All iPhones appear to log your location to a file called 'consolidated.db.' This contains latitude-longitude coordinates along with a timestamp. The coordinates aren't always exact, but they are pretty detailed. There can be tens of thousands of data points in this file, and it appears the collection started with iOS 4, so there's typically around a year's worth of information at this point. Our best guess is that the location is determined by cell-tower triangulation, and the timing of the recording is erratic, with a widely varying frequency of updates that may be triggered by traveling between cells or activity on the phone itself.While the consolidated.db file has been known for some time and has played a key role in forensic investigations of iOS devices by law enforcement agencies, the researchers note the data is available on the devices themselves and in backups in unencrypted and unprotected form, leading to significant privacy concerns. Once gathered, the data is saved in backups, restored to devices if necessary, and even migrated across devices, offering a lengthy history of a user's movement.
