Smart home devices needn’t reveal users’ data. A ring could perform a similar function in public.
Navigation and weather apps (along with many others) store users’ location data. Now, a university team from Munich has developed a new method to prevent such data being used to infer private information.
The basis for the method is a digital grid system which divides the earth’s surface into hexagonal cells. The user’s location in this grid, which can be specified to different levels of precision, is encrypted with the help of floating-point numbers.
Only this information is passed to the app. It’s proof enough and simultaneously affords users increased privacy.
Data protection is just as important when it comes to musicians’ intellectual property.
