What is Multi-Party Computation?

We know how to secure data in storage using E2EE, but is it possible to ensure data privacy even while processing it server-side? This is the first in a series of articles I'll be writing covering the privacy-enhancing technologies being rolled out.

Privacy and Security on Mastodon

Mastodon is an open-source and decentralized social network that has been growing in popularity for the past few years.

While most social media rely on commercial models harvesting users' data to sell to advertisers, Mastodon offers a human-centric alternative that doesn't seek profits from your data and attention. This means better social connections, better controls, and better privacy.

In Praise of Tor: Why You Should Support and Use Tor

You might have heard of Tor in the news a few times, yet never dared to try it yourself. Despite being around for decades, Tor is still a tool too few people know about.

Today, Tor is easy to use for anyone. It helps not only journalists and activists, but anybody who seeks greater privacy online or access to information regardless of location. But what is Tor exactly? How can Tor help you? And why is it such an important tool?

Privacy Pass: The New Protocol for Private Authentication

Services that require authentication can correlate your activity on that service with your account, and that account is normally linked with payment information that could potentially link back to your real identity. With the Privacy Pass protocol, it doesn't have to be that way.

Privacy is Also Protecting the Data of Others

In privacy, we talk a lot about how to protect our own data, but what about our responsibility to protect the data of others?

If you care about privacy rights, you must also care for the data of the people around you. To make privacy work, we need to develop a culture that normalizes caring for everyone's data, not just our own. Privacy cannot solely be a personal responsibility, data privacy is team work.

Toward a Passwordless Future

Passwords are annoying, vulnerable to attack, and prone to human error. The multitude of issues with passwords has cost millions of dollars and forced terrible band-aid solutions in how we handle signing up for, logging in to, and securing online accounts. I'd like to break down some of these design paradigms that have entrenched themselves in our lives and how passkeys can lead to more secure and private online accounts.

Biometrics Explained

Biometrics are a convenient and secure way to authenticate our devices. Many of us use and trust the biometrics of our devices without much thought, but are they really secure? With so many options, which ones are the best?
