A new feature on the encrypted messaging platform Signal, "Sealed Sender," will hide your identity from Signal itself, so that if the company is ever compromised, it will not be able to reveal who sent messages to whom.
Sealed Sender is cleverly implemented to fight spam and abuse; you can turn Sealed Sender on selectively, only allowing sealed messages where you and the other party appear in one another's address books (and you can also block sealed messages from specific individuals, even if they appear in your address book and vice-versa).
Signal uses Amazon Web Services for hosting, and says that it is still working on finding a viable way to encrypt IP addresses and other metadata that could theoretically allow an attacker to perform certain types of user traffic analysis. And encrypted messaging still isn't a magic bullet, especially if you leave message threads on your device. But Green emphasizes that every incremental step is valuable. The difficulty of developing the technical frameworks for these steps is one reason WhatsApp cofounder Brian Acton donated $50 million in February to support Signal's development. The more of a barren data wasteland it is inside of Signal, the better.

Private Join and Compute is a new free/open Google tool that implements the longstanding cryptographic concept of "commutative encryption," which allows untrusted parties to merge their datasets without revealing their contents to one another, do mathematical work on the data, and learn the outcome of that work without either of them seeing the underlying data.
Writer and data journalist Kevin Litman-Navarro subjected 150 privacy policies from leading online services to programmatic analysis for complexity (the Lexile test), and found them to be an incomprehensible mess second only to Kant's Critique of Pure Reason in their lack of clarity.
The Great State of Maine, having jettisoned its far-right lunatic "government" and replaced it with a responsive, progressive, evidence-based one, is now set to pass the nation's most stringent ISP privacy law, going further than both New York and California.
