John Burcham Mobile Messaging Audio Transcript
Within the context of mobile messaging, a lot of people have questions about privacy.
One of the key features is the level of encryption that is offered by the different service providers.
Encryption can be a generic word, but there are a lot of different types of encryption.
The two to look for in particular are link encryption and end-to-end encryption, with end-to-end encryption being the one that you would prefer.
End-to-end encryption is a system where it is encrypted on the device that is sending the message, and then it is decrypted at the level of the device that is receiving the message.
So if I send you a message, I’m coding it, and you’re decoding it.
It’s a very straightforward process, and through the entire transmission, it stays encrypted.
What that means is that no one else can read it, which includes the company that is providing the service.
The difference would be link encryption.
Link encryption is when the company that provides the service is doing the encryption somewhere else, and is keeping it in an encrypted form.
That means that you have a third party in your conversation, it’s no longer me and you, it’s me and you and Facebook.
A good example would be the two different kinds of messaging services that Facebook offers – the first being a traditional Facebook message, and the second being a Facebook Secret Conversation.
A generic Facebook message is between me and you. However, it’s going through Facebook’s servers and Facebook will have a record and a copy of that message.
With Secret Conversations instead, at the point where you send the message, my computer is encrypting it, it stays encrypted on the entire trip to you, and then your device decrypts it.
Now you have a conversation that’s just between me and you, which adds to the level of privacy that you can expect.
Within the available apps that are out there today, your privacy is something that you have an option with regards to.
There are apps out there that use end-to-end encryption in a very solid way so that the likelihood that your message would ever go to anyone other than the person you intend is virtually nonexistent.
But that’s that key thing to look for – what your expectation is, and once you know what your expectation is, you should be able to go out and find the right app that works for you.
