The simplest answer is to avoid passing back the additional data. We also need to worry about the default behavior if the device doesn't have a sensor or it is switched off and for an external reason can't be automatically switched back on. The min, max and default values are all potentially useful for finger printing. Users may be more concerned about the performance of an application, which may depend on the application being able to tune the sensor events appropriately, so we may not want to be too strident about finger printing risks. This plays into the larger discussion of the future of online privacy and what will follow on after Do Not Track. -- Dave Raggett <dsr@w3.org> http://www.w3.org/People/Raggett
