Due to the exceptional development of room sharing apps  along with the daily news about theft of private images and videos, privacy concerns in those places that should be  considered inviolable remains as topical as ever.  

Despite the regulations in place and the severe penalties for those who infringe on the right to privacy, all of us travelers, as soon as we checked into our new temporary home, tried to ignore at least once that voice in our heads that wondered " what if someone is spying on me?" 

Not that theft of compromising images and videos can only happen when renting a private room, deep web chronicles are littered with stolen videos recorded in hotels, toilets of bars and restaurants, on transportation... 

Fortunately, there are free and easily downloadable applications that can help us control the situation as soon as we take possession of a space that should be private. 

The first app is called Fing and it allows us to detect all the devices around us that are using a wifi connection. The app lists all devices by their IP address and in most cases manages to arrive at a textual description of the object (phone, camera, smart TV, etc...). The limitation is that the devices must be on the same wifi network as the phone in order to be detected. 

The second app is called LightBlue   and is able to track all nearby Bluetooth devices, even indicating the distance to the device in real time so you can find them quickly. 

Always considering that the best weapon to ensure one's privacy when traveling is a fair amount of common sense when booking, these apps can really be very useful to avoid nasty surprises.
