We know Facebook’s ability to leverage their data sets is what drives their revenue stream, and we know those data sets can be used for remarkable (read:disturbing) things…like swinging a US Election.
Any onlookers trying to read the messages would see a scrambled mess, unless they too had access to the private key to decrypt the conversation. Using this contact address, or public key, the person messaging you is able to encrypt the message data being sent, which can only be decrypted using the associated private key. It’s like your contact address people use to message you.
Similarly, in the context of encrypted messaging, you give your public key to people so they can use it to message you. Think of the public key as your bank account number - you give that out to people if you want to receive money. If your message is flagged, your supposedly encrypted message will be copied and sent back to Facebook’s servers for further analysis.Įnd-to-end encryption is a process where the user generates a set of keys, one public and one private, allowing messages to be received and decoded. WhatsApp, Facebook’s “end-to-end encrypted messaging” application is undergoing renovations to build a backdoor allowing message contents to be scanned before messages are sent. Facebook is in the news again, and there’s no surprise that their data management practices are the cause.
