These wearable devices, which can track heart rate Air Vapormax Black , steps takenand calories burned, are getting more and more popular amongconsumers around the world.
But exploiting security weak spots in the communicationprocedures of some gadgets could allow unauthorized sharing ofpersonal data with third parties, including online retailers andmarketing agencies, according to the study. It was carried out byresearchers from The University of Edinburgh and their colleaguesin Germany and Italy.
An Edinburgh team carried out an in-depth security analysis oftwo popular models of wearable fitness trackers made by Fitbit.
They discovered a way of intercepting messages transmittedbetween fitness trackers and cloud servers Air Vapormax Flyknit , where data is sent foranalysis. This allowed them to access personal information andcreate false activity records.
The team even demonstrated how the system that keeps data on thedevices secure -- called end-to-end encryption -- can becircumvented. By dismantling devices and modifying informationstored in their memory, researchers bypassed the encryption systemand gained access to stored data.
In response to the findings, Fitbit has developed softwarepatches to improve the privacy and security of its devices,according to the team.
Our work demonstrates that security and privacy measuresimplemented in popular wearable devices continue to lag behind thepace of new technology development Air Vapormax , said Dr. Paul Patras, from TheUniversity of Edinburgh.
"We welcome Fitbit's receptiveness to our findings, theirprofessional attitude towards understanding the vulnerabilities weidentified and the timely manner in which they have improved theaffected services," Patras also said.

LOS ANGELES, Sept. 7 (Xinhua) -- U.S. researchers have reported Thursday the first detection of sea level "fingerprints" in ocean observations: detectable patterns of sea level variability around the world resulting from changes in water storage on Earth's continents and in the mass of ice sheets.
The findings, published Thursday in the journal Geophysical Research Letters, may help scientists to determine how much the sea level will rise at any point on the global ocean as a result of glacier ice melt Nike Vapormax Triple Navy , according to the U.S. National Aeronautics and Space Administration (NASA)'s Jet Propulsion Laboratory (JPL).
As ice sheets and glaciers undergo climate-related melting, they alter Earth's gravity field, resulting in sea level changes that aren't uniform around the globe. The resulting pattern of sea level change is known as a sea level "fingerprint".
"Scientists have a solid understanding of the physics of sea level fingerprints, but we've never had a direct detection of the phenomenon until now Nike Vapormax Flyknit Triple Gold ," said co-author Isabella Velicogna, professor of Earth system science at the University of California, Irvine (UCI), and JPL research scientist.
To calculate sea level fingerprints associated with the loss of ice from glaciers and ice sheets and from changes in land water storage Nike Vapormax Triple Gold , researchers from JPL and UCI used gravity data collected by the twin satellites of the U.S.German Gravity Recovery and Climate Experiment (GRACE) between April 2002 and October 2014.
During that time, the loss of mass from land ice and from changes in land water storage increased global average sea level by about 0.07 inch (1.8 millimeters) per year, with 43 percent of the increased water mass coming from Greenland, 16 percent from Antarctica and 30 percent from mountain glaciers Nike Vapormax Flyknit Triple White , according to the study.
The scientists then verified their calculations of sea level fingerprints using readings of ocean-bottom pressure from stations in the tropics.

CANBERRA, Aug. 17 (Xinhua) -- A sudden explosion of algae which occurred 650 million years ago was the catalyst for how the first animals appeared on earth, according to the results of a study led by Australian researchers.
In a statement released on Thursday, Associate Professor Jochen Brocks from the Australian National University (ANU) said his team "crushed" ancient sedimentary rocks into a fine powder in order to closely analyze their contents.
Brocks said that the researchers were able to backdate traces of organisms as far back as 650 million years ago.
"We crushed these rocks to powder and extracted molecules of ancient organisms from them Nike Vapormax Triple White ," Brocks said.
"These molecules tell us that it really became interesting 650 million years ago. It was a revolution of ecosystems, it was the rise of algae."
He said the timeline shows that the algal bloom formed after a 50 million year-long ice age; glaciers and ice formations "ground entire mountain ranges to powder" in a development which released nutrients into oceans.
