Signal Protocol — Open Source, Private, Encrypted Mobile Messaging App
Signal is a new Protocol and Mobile Communications App that is Fully Private and Encrypted unlike its counterparts such as WhatsApp and Facebook. This is a big deal in Information Security and Data Privacy especially at this moment in time in 2021 and many tech titans such as Elon Musk and Jack Dorsey are advocating for Signal and for people to use more private protocols like these. This is not only because they are for freedom of speech and against cancel culture and deplatforming but also because these types of apps represent a threat to the current Big Tech Companies and their business models that fuel surveillance capitalism.

This is because many large tech companies such as Facebook not only collect massive amounts of user data which they sell to unknown third parties in the attention, ad-tech driven and surveillance capitalist business model which they have built, but because they also can deplatform or “cancel” anyone they don’t agree with or who might have opposing thoughts which are deemed as conflicts of interest.
Signal doesn’t store any personal data or contact information and is highly transparent about their work because they use open-source and peer-reviewed technology and their organization is a nonprofit funded entirely by grants and donations unlike a for-profit corporation. This is a nice technical video which covers everything from how Signal works, the privacy framework behind it, their foundational structure and the security and design features they have from encryption to user interface.
