Okay, folks, it's time to talk security again. I've proselytized email security and two-factor authentication in the past, and now I'm going to tell you about voice calls. I was going to say phone calls, but we're way beyond – and in many ways simpler than – the traditional telephone model.
But first, some fundamentals…
Back a long time ago (10 or 20 years ago), people had to use the phone company to connect their calls. They would pay Ma Bell a monthly fee and get a phone number in return. The phone companies took care of connecting all the calls for us. There were laws to protect persons from eavesdropping, and to wiretap someone meant that you had to physically connect a device to the phone line somewhere along the signal path between your phone and grandma's phone. (Gotta get that secret family recipe for chocolate chip cookies…)
Jump-cut to now: Customers still have the same experience, i.e., pick up a phone, dial a number, etc., but the technology between the two endpoints (you and grandma) is significantly different. It's all electronic and digital and computerized and stuff. What this essentially means for you is that if someone wanted to record your phone call (never mind the metadata about it), all he would have to do is check a little box somewhere or enter your phone number or some other thing that identifies you in a computer database somewhere and – BAM – all of your calls are being recorded or otherwise monitored. (Note: this is a bit different than snooping email because as the servers along the route store and forward the email, they're supposed to make a copy of your email – it's by design. Betcha didn't know that, did ya?)
So maybe the NSA isn't recording our phone calls. Maybe they don't have humans listening in. But that doesn't mean that fancy dancy computer programs aren't listening for certain words or phrases automatically. Police departments do something similar with automatic license plate scanning to find stolen vehicles. Courts have said that it's not special treatment if everyone gets scanned, that way human prejudice doesn't play into it.
At any rate, the point is that anyone along your network path can record your phone calls, especially if it's Internet-based or digital. I'm not so worried about the government doing it as I am concerned with the possibility that creative criminals could listen in on your conversations. (Most crimes are crimes of opportunity, and digital technology makes it very easy.) True, most phone calls are exceptionally boring, but every once in a while I need to tell someone a bank account number, credit card number, or PIN over the phone because they haven't friggin’ implemented secure email yet!!! And all my calling is done over the public Internet (see: it's CHEAP) that eventually connects me to the POTS (plain ol’ telephone service). Heck, if I can record and decode a phone call over my home network, it ain't that hard, folks.
What's the answer?
So, what if you could have totally encrypted calls that just, oh, I don't know, bypassed all this antiquated and expensive telephone infrastructure. After all, every computer and mobile phone nowadays has Internet access, right? Could I use something easier to remember like an email address or username or something? Couldn't my Android phone call your iPhone directly using the Internet and we could have the two devices talk to each other without any other servers or anything in the way? Well good news: now you can! And it's super easy, too. Plus, it's kinda fun and you feel a little bit like James Bond when you make a call.
Oh, by the way, I should also mention that the default technology used in OSTN to get your voice from point A to point B is twice as clear as normal phone calls. Seriously, I do this stuff for a living. Once you've experienced HD Voice (or wideband, or G.722, or whatever you want to call it), you'll never want to go back to regular (narrowband) phone calls again.
And did I mention it's free?
Encrypted like spy technology
Twice as clear as regular phone calls
