POCSAG512, POCSAG1200 and POCSAG2400 is the protocol used by pagers to transmit information to one another. The problem I'm seeing here is that it is not encrypted, only encoded, as any broadcast has to be to be broadcast in the first place.
I decided to build a simple web page that decodes and displays local pager POCSAG transmissions I can pick up (with my $30 of radio receiving equipment and a linux vm) as a show of just how insecure it it.
However, it just feels illegal.
There is stuff here that says it is confidential, and shouldn't be shared. Considering it is a public broadcast that is not encrypted, how is it dissimilar to just yelling, in a public place, "What I'm about to say is confidential and should not be heard by anyone".
Any heads up or pointers? I've already brought this up with a friend of mine studying to be a lawyer, and he gave me an all-encompassing shrug.
