Fraud and data theft are possible in many major trackers, new study finds
About 20 million fitness trackers of various sorts were sold in the first quarter of 2016. That's a lot of people out there who are worried about their fitness levels.
But according to a new study, those people should be more worried about the security of the data that their trackers are collecting. Researchers from the Technische Universität Darmstadt and the University of Padua looked at 17 models of fitness tracker currently on the market and found big holes in their security.
While almost all cloud-based tracking systems use an encrypted protocol like HTTPS to transfer their data, the researchers were able to falsify data in almost all cases. In one example, they successfully persuaded the tracker to tell its server that the user had walked 80 million steps in a day.
