Today, while counting tiles at the bottom of the pool during swim training, one thing hit me (and it was not another swimmer).

It’s about the safety of our personal data and details. When I think about this I mostly think about the ways to keep my data safe, both the data on my computer and on the cloud services I use, but, as more and more data is shared to the cloud automatically there is more to it than meets the eye.

The thing is that data sharing that might look like it can not harm you, for example, sharing your training details (the route you took to run or bike, heart rate, pace, etc) within a couple of friends on a sports social network means that you are now dependent on their security measures to keep your data private. If anyone can access your friends accounts because they use an easy to guess password, your security is immediately jeopardised.

For example, with a little research anyone can figure out where you live and having access to your training log they can easily tell that you are away from home. Some services even allow for real time training sharing so someone could know exactly where you are at any given moment.

Just some food for thought.
