It’s shockingly easy to buy sensitive data about US military personnel

For as little as $0.12 per record, data brokers in the US are selling sensitive private data about both active-duty military members and veterans, including their names, addresses, geolocation, net worth, and religion, and information about their children and health conditions. 

In an unsettling study published today, researchers from Duke University approached 12 data brokers and purchased thousands of records about American service members with minimal vetting.

The study highlights the extreme privacy and national security risks created by data brokers. These companies are part of a shadowy multibillion-dollar industry that collects, aggregates, buys, and sells data, practices that are currently legal in the US, exacerbating the erosion of personal and consumer privacy.

The inside scoop on watermarking and content authentication

Last week, President Biden released his executive order on AI, a sweeping set of rules and guidelines designed to improve AI safety and security. The order put great emphasis on watermarking and content authentication tools, which aim to label content to determine whether it was made by a machine or a human. The White House is making a big bet on these methods as a way to fight AI-generated misinformation.

The White House is encouraging tech companies to create new tools to help consumers discern if audio and visual content is AI-generated, and plans to work with the group behind the open-source internet protocol known as the Coalition for Content Provenance and Authenticity, or C2PA. Tate Ryan-Mosley, our senior tech policy reporter, has written a handy guide to C2PA, what it can achieve, and, crucially, what it can’t. Read the full story.

How AI impacts free speech online

AI is everywhere right now. But while it may not have constitutional rights, is the content it creates or serves up protected speech? This is just one of the fascinating topics we'll be exploring at EmTech MIT 2023, our flagship technology event kicking off 14 November.

The big story

What does GPT-3 “know” about me? 

August 2022

One of the biggest stories in tech is the rise of large language models that produce text that reads like a human might have written it.

These models’ power comes from being trained on troves of publicly available human-created text hoovered up from the internet. If you’ve posted anything even remotely personal in English on the internet, chances are your data might be part of some of the world’s most popular LLMs. 

Melissa Heikkilä, MIT Technology Review’s AI reporter, wondered what data these models might have on her—and how it could be misused. So she put OpenAI’s GPT-3 to the test. Read about what she found.
