Privacy for Agentic AI

Sooner or later, it’s going to happen. AI systems will start acting as agents, doing things on our behalf with some degree of autonomy. I think it’s worth thinking about the security of that now, while its still a nascent idea.

In 2019, I joined Inrupt, a company that is commercializing Tim Berners-Lee’s open protocol for distributed data ownership. We are working on a digital wallet that can make use of AI in this way. (We used to call it an “active wallet.” Now we’re calling it an “agentic wallet.”)

I talked about this a bit at the RSA Conference earlier this week, in my keynote talk about AI and trust. Any useful AI assistant is going to require a level of access—and therefore trust—that rivals what we currently our email provider, social network, or smartphone.

This Active Wallet is an example of an AI assistant. It’ll combine personal information about you, transactional data that you are a party to, and general information about the world. And use that to answer questions, make predictions, and ultimately act on your behalf. We have demos of this running right now. At least in its early stages. Making it work is going require an extraordinary amount of trust in the system. This requires integrity. Which is why we’re building protections in from the beginning.

Visa is also thinking about this. It just announced a protocol that uses AI to help people make purchasing decisions.

I like Visa’s approach because it’s an AI-agnostic standard. I worry a lot about lock-in and monopolization of this space, so anything that lets people easily switch between AI models is good. And I like that Visa is working with Inrupt so that the data is decentralized as well. Here’s our announcement about its announcement:

This isn’t a new relationship—we’ve been working together for over two years. We’ve conducted a successful POC and now we’re standing up a sandbox inside Visa so merchants, financial institutions and LLM providers can test our Agentic Wallets alongside the rest of Visa’s suite of Intelligent Commerce APIs.

For that matter, we welcome any other company that wants to engage in the world of personal, consented Agentic Commerce to come work with us as well.

I joined Inrupt years ago because I thought that Solid could do for personal data what HTML did for published information. I liked that the protocol was an open standard, and that it distributed data instead of centralizing it. AI agents need decentralized data. “Wallet” is a good metaphor for personal data stores. I’m hoping this is another step towards adoption.

Windscribe Acquitted on Charges of Not Collecting Users’ Data

The company doesn’t keep logs, so couldn’t turn over data:

Windscribe, a globally used privacy-first VPN service, announced today that its founder, Yegor Sak, has been fully acquitted by a court in Athens, Greece, following a two-year legal battle in which Sak was personally charged in connection with an alleged internet offence by an unknown user of the service.

The case centred around a Windscribe-owned server in Finland that was allegedly used to breach a system in Greece. Greek authorities, in cooperation with INTERPOL, traced the IP address to Windscribe’s infrastructure and, unlike standard international procedures, proceeded to initiate criminal proceedings against Sak himself, rather than pursuing information through standard corporate channels.

DIRNSA Fired

In “Secrets and Lies” (2000), I wrote:

It is poor civic hygiene to install technologies that could someday facilitate a police state.

It’s something a bunch of us were saying at the time, in reference to the vast NSA’s surveillance capabilities.

I have been thinking of that quote a lot as I read news stories of President Trump firing the Director of the National Security Agency. General Timothy Haugh.

A couple of weeks ago, I wrote:

We don’t know what pressure the Trump administration is using to make intelligence services fall into line, but it isn’t crazy to worry that the NSA might again start monitoring domestic communications.

The NSA already spies on Americans in a variety of ways. But that’s always been a sideline to its main mission: spying on the rest of the world. Once Trump replaces Haugh with a loyalist, the NSA’s vast surveillance apparatus can be refocused domestically.

Giving that agency all those powers in the 1990s, in the 2000s after the terrorist attacks of 9/11, and in the 2010s was always a mistake. I fear that we are about to learn how big a mistake it was.

Here’s PGP creator Phil Zimmerman in 1996, spelling it out even more clearly:

The Clinton Administration seems to be attempting to deploy and entrench a communications infrastructure that would deny the citizenry the ability to protect its privacy. This is unsettling because in a democracy, it is possible for bad people to occasionally get elected—sometimes very bad people. Normally, a well-functioning democracy has ways to remove these people from power. But the wrong technology infrastructure could allow such a future government to watch every move anyone makes to oppose it. It could very well be the last government we ever elect.

When making public policy decisions about new technologies for the government, I think one should ask oneself which technologies would best strengthen the hand of a police state. Then, do not allow the government to deploy those technologies. This is simply a matter of good civic hygiene.

UK Is Ordering Apple to Break Its Own Encryption

The Washington Post is reporting that the UK government has served Apple with a “technical capability notice” as defined by the 2016 Investigatory Powers Act, requiring it to break the Advanced Data Protection encryption in iCloud for the benefit of law enforcement.

This is a big deal, and something we in the security community have worried was coming for a while now.

The law, known by critics as the Snoopers’ Charter, makes it a criminal offense to reveal that the government has even made such a demand. An Apple spokesman declined to comment.

Apple can appeal the U.K. capability notice to a secret technical panel, which would consider arguments about the expense of the requirement, and to a judge who would weigh whether the request was in proportion to the government’s needs. But the law does not permit Apple to delay complying during an appeal.

In March, when the company was on notice that such a requirement might be coming, it told Parliament: “There is no reason why the U.K. [government] should have the authority to decide for citizens of the world whether they can avail themselves of the proven security benefits that flow from end-to-end encryption.”

Apple is likely to turn the feature off for UK users rather than break it for everyone worldwide. Of course, UK users will be able to spoof their location. But this might not be enough. According to the law, Apple would not be able to offer the feature to anyone who is in the UK at any point: for example, a visitor from the US.

And what happens next? Australia has a law enabling it to ask for the same thing. Will it? Will even more countries follow?

This is madness.

The Scale of Geoblocking by Nation

Interesting analysis:

We introduce and explore a little-known threat to digital equality and freedom­websites geoblocking users in response to political risks from sanctions. U.S. policy prioritizes internet freedom and access to information in repressive regimes. Clarifying distinctions between free and paid websites, allowing trunk cables to repressive states, enforcing transparency in geoblocking, and removing ambiguity about sanctions compliance are concrete steps the U.S. can take to ensure it does not undermine its own aims.

The paper: “Digital Discrimination of Users in Sanctioned States: The Case of the Cuba Embargo”:

Abstract: We present one of the first in-depth and systematic end-user centered investigations into the effects of sanctions on geoblocking, specifically in the case of Cuba. We conduct network measurements on the Tranco Top 10K domains and complement our findings with a small-scale user study with a questionnaire. We identify 546 domains subject to geoblocking across all layers of the network stack, ranging from DNS failures to HTTP(S) response pages with a variety of status codes. Through this work, we discover a lack of user-facing transparency; we find 88% of geoblocked domains do not serve informative notice of why they are blocked. Further, we highlight a lack of measurement-level transparency, even among HTTP(S) blockpage responses. Notably, we identify 32 instances of blockpage responses served with 200 OK status codes, despite not returning the requested content. Finally, we note the inefficacy of current improvement strategies and make recommendations to both service providers and policymakers to reduce Internet fragmentation.
