Eric Lichaj World Cup Jersey , Sept. 14 (Xinhua) -- Vulnerabilities in wearable fitnesstrackers could threaten the privacy and security of the data theyrecord, and manufacturers need to improve these products to betterprotect users' personal data, according to a study publishedThursday by the University of Edinburgh.
These wearable devices, which can track heart rate, 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
Dax McCarty World Cup Jersey , 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, 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, said Dr. Paul Patras, from TheUniversity of Edinburgh.
"We welcome Fitbit's receptiveness to our findings

To help manufacturers remove similar weaknesses from futuresystem designs, the team has produced specific guidelines.Enditem

Cuba's capital was chosen to host the 6th edition of the celebration in part because of its many great musicians and Latin jazz heritage, said Bokova, who was accompanied by jazz greats Chucho Valdes and Herbie Hancock.
"Havana is a natural city of music and cultural heritage, and we also chose to celebrate it here because Cuba this year marks the 70th anniversary of establishing relations with UNESCO," she added.
Jazz has become a universal language the world really needs due to today's many social and economic conflicts, she said.
UNESCO has partnered once again with the U.S.-based Thelonious Monk Institute of Jazz

In the past three decades, the ties of cooperation between UNESCO and Cuba have grown "deep roots," said the UN official.
"Our regional office for all of Latin America and the Caribbean is in Cuba and this nation has a commitment to developing cultural diversity, protecting and conserving cultural heritage ... and the celebration of this day here is a proof of our strong ties," she said.
"Our elder and younger jazz musicians are living in a good era (for jazz) and the opportunity to celebrate International Jazz Day in Cuba is a really good accomplishment," Valdes said.

"This year's focus on Cuba is a testament to the power of jazz as we bring women and men together around shared values and aspirations
