Private conversations should be kept private. When we launch a call, send a text or even engage with someone via FaceTime (News - Alert), we expect that only those we let into the conversation will actually be a part of it. Not long ago, however, we learned that the United States National Security Agency was interested in our phone calls and was listening in a bit more than we anticipated.

This news put everyone on high alert, from the individual consumer to the multi-million-dollar corporation. Communication sharing was no longer secure and voice encryption was getting more attention. A recent Digital Trends report highlighted this trend, stressing the fact that companies need to go beyond standard SSL encryption available with most email services. Why? Unencrypted versions of the data are still kept by most companies, putting more focus on the need for end-to-end encryption services.

Then there’s the smartphone. While we tend to forget that they can actually make calls, these handy devices still meet this need and are as vulnerable as anything we have available today. If you’re relying on a major service provider to support your calls, you’re basically making the communication available for anyone with a reason to listen. If your communications are nothing special, it may not matter. But, if you’re a corporate user and your information is proprietary, it’s time to make a change.

There are a number of different options available on the market that can allow for easy encryption of voice calls and video exchanges. One free and open source solution for call encryption for Android (News - Alert) users is the RedPhone from WhisperSystems. As long as the user is talking with another RedPhone user, the call can be encrypted and secure. Plus, users don’t waste minutes as calls are completed over Wi-Fi connections.

Conference calls can also be encrypted end-to-end with the use of SilentPhone. A user is assigned a unique 10-digit phone number that interacts with existing contacts on their phone, known as circles. These circles exist to provide for completely secure calling without agreeing to a monthly contract. If this type of commitment doesn’t offend, $24 a month can get the user a subscription that allows them to include individuals outside of their circles. The point, of course, is to support the necessary communications without the unnecessary eaves dropping.

This is one area where Cryptocall excels. The company brings to market a voice encryption product in a fully self-contained system. Cryptocall was on hand at this year’s ITEXPO (News - Alert) to demonstrate its latest innovations and TMCnet’s Rachel Ramsey caught up with them on the show floor. To catch up on their latest, check out their conversation in full in this ITEXPO video.
