A KEY PART of what makes Signal the leading encrypted messaging app is its effort to minimize the amount of data or metadata each message leaves behind. The messages themselves are fully encrypted as they move across Signal’s infrastructure, and the service doesn’t store logs of information like who sends messages to each other, or when. On Monday, the nonprofit that develops Signal announced a new initiative to take those protections even further. Now, it hopes to encrypt even information about which users are messaging each other on the platform.
As much as it values privacy, Signal still needs to see where messages are going so that it can deliver them to the right account. The service has also relied on seeing what account a message came from to help verify that the sender is legit, limit the number of messages an account sends in a period of time to prevent it from spewing spam, and offer other types of anti-abuse checks.
