This time about security and safety.

Imagine you or somebody walking deserted place then suddenly stalked by individual.

We all have smartphones already. We could just reach our phone and press on button - applet that :

-momentarily start sending video footage to that Secure Evidence Server
-GPS tag your current location
-contact 911 or 111 emergency if required

So whole concept is about single to launch applet on our phone to send video footage to be recorded , protected from erasing.

Now we could be mugged, raped or just nothing happen at all. But in case we have evidence what actually happen or just simple emergency tool.

For example we witness any road , fire or other bombing accident. We press button and video message is automatically send to Secure Evidence Server.
Police investigating later could just look at Secure Server for specific geo tag and find for example 12 recordings from different people at the specific location.
Additional value for rescuers receiving such video evidence call is real time picture of the scene -that allow them better prepare to situation.
If idea / concept could get traction, maybe even in the future special purpose Red Panic Button could be incorporated into every mobile phone ?
