Signal, the end-to-end encrypted messaging app, is planning to roll out a new feature that aims to hide the sender’s identity from potential attackers trying to intercept the communication. The Sealed Sender feature will be enabled by default in the upcoming version of Signal. Signal never stores metadata or logs of information on its users like who sends messages to each other and when, but the new feature would protect the Sender’s identity in case the communication is somehow intercepted. Signal is also finding ways to encrypt IP addresses and other sensitive metadata information that could be revealed by analyzing users’ network traffic.
