I need to chat with someone while no one else is listening or monitoring our conversation. I can only share information with them if I know that no one else will find it out.
You are preparing an online meeting with one or more colleagues and you need to share confidential information with them. You need to be sure that no one can actively monitor or passively collect the content or any other information related to your conversation.
Chatting tools are like the rest of the communication tools we use on daily basis: they could be monitored and have different levels of risks. When using chatting applications, be aware that they are either:
- End-to-end encrypted, which means that only you and the receiver can read the messages and no one else can.
- Encrypted to the server, which means your connections to the service provider are secure but requires you to trust your service provider (Microsoft in the case of Skype, Google in the case of Gchat).
- Not encrypted at all, which means that anyone watching your communication could see your messages in plain text.
You must also trust the application. The only way to judge the security of an application and verify its privacy claims is to review its code in an open and transparent manner. Applications that provide their code for community review are classified as free/libre and open source software (FLOSS). FLOSS applications are generally trustworthy.
Most popular applications don’t prioritise user privacy and security. While your contacts may be using these popular services, we recommend that you stop using Viber, WhatsApp, Facebook Chat, Gchat and Telegram because they don’t implement security measures transparently.
