Privacy by Design - A look back and a look forward

From X.400 to SMTP: The Story of a Simpler Takeover In the early days of digital communication, there were two competing visions for email. One was the complex, feature-rich, and highly structured X.400 standard, championed by the International Telecommunication Union (ITU). The other was the simpler, more flexible Simple Mail Transfer Protocol (SMTP), which emerged from the internet’s open and collaborative development. Ultimately, SMTP and complementary protocols like PGP (Pretty Good Privacy) prevailed due to their simplicity, adaptability, and the decentralized nature of the internet.

Privacy by Design & the EU Data Wallet

From X.400 to SD-JWT: A Privacy Evolution in the EU Digital Identity Wallet The landscape of digital identity is constantly evolving, and with the advent of the EU Digital Identity (EUDI) Wallet, we’re seeing a significant leap towards user-centric and privacy-respecting systems. For those of us with a longer history in digital communication, the term “X.400” might ring a bell. While seemingly disparate, comparing the foundational concepts behind X.400 and the modern SD-JWT (Selective Disclosure for JSON Web Tokens) within the context of the EUDI Wallet highlights a remarkable evolution, particularly in how we handle and control personal data.

Privacy by Design Comes to the fore

Enhancing Privacy and Security in Messaging with SD-JWT In a world where our digital conversations are the new frontier of personal data, the security and privacy of our messaging applications are more critical than ever. We’ve all grown accustomed to end-to-end encryption, which is a great first step, but what happens when you need to share personal information within a conversation? SD-JWT (Selective Disclosure for JSON Web Tokens) offers a powerful solution that can take messaging privacy to a whole new level.
