PHOENIX (KSAZ) - There are a number of companies that allow you to share details of your athletic abilities online after tracking your every calorie burned, but that competitive side of you may put you at a risk for sharing too much information.
While tracking your run, hike or bike workout on a fitness device may not seem like a big deal, your data showing your movement could end up posted online, for anyone to see?
"The danger is it's an invasion of privacy," said Andy Jordan, the Special Projects lead for a cyber security firm called Mosaic 451.
Jordan says technology is constantly growing and evolving.
"Different abuse cases of how Internet of Things could become, as drastic as it sounds, a biological weapon," said Jordan. "Instead of going after one person, you go after an entire group of people."
A fitness app called Strava draws out heat maps of where people are working out, and publishes them online, showing where that person or group of people are located geographically. Jordan says this can become a security threat to areas like military bases, especially those abroad, if the information gets into the wrong hands.
"You can start seeing patrol patterns. You can start seeing gaps within physical security that someone could maliciously exploit, that you could try to sneak into a miliatry base is probably one of the more frightening pieces that many would have," said Jordan.
As for the average athlete, Jordan says things like stalking could arise.
"I loaded it up this morning, and there's a couple running routes through the muontain routes in Phoenix, and it's interesting to see the different routes that people are taking, and as you drill into these routes, you can see who the leaderboards are, and where I think there's a potential invasion of privacy that becomes, if they've linked their Gmail to Facebook. Up to tha,t I can know they're in those forms and that becomes a form of stalking," said Jordan.
Beyond that, online fitness data can even affect places you're physically not at
"The other side is, they know that they're not home," said Jordan.
Hikers and runners out getting their daily exercise say they aren't too concerned about how they use their fitness trackers.
"Be able to know where I am at, just in case I get lost, it works for me," said a woman. "I'm not too worried."
"I think its useful in a way to keep you motivated to reach a goal, but in the same time, you want to keep that data to yourself, and not have it shared publicly," said a man.
Strava does give users the option not to share their data. In a statement emailed to Fox News. "It excludes activities that have been marked as private and user-defined privacy zones." Strava officials go on to say, "We are committed to helping people better understand settings, to give them control over what they share."
Jordan says its important to always know just how much of your information is not so personal thanks to technology.
"You can go into your phone and turn off location services," said Jordan. "You can make sure you're not sending out GPS data attached to your photos."
The Department of Defense isn't really happy with the fitness apps either, because it can be used to track the location of military personnel overseas. It's now working on a policy for those who are wearing the devices, but there is no decision yet.
