Privacy-enhancing technologies will not be worthwhile differentiators if users can't confirm apps use them and apps can't credibly advertise them as a feature. Starting today, anyone motivated to help address this gap and to make PETs more competitive can run a Blacklight node.
Nillion@nillion

Nillion Blacklight is a decentralized network that verifies private workloads running on the Blind Computer. It checks that workloads are running correctly and honestly inside secure enclaves (TEEs), without revealing user data or execution logic. This verification is done by Blacklight nodes.

APIs transformed the developer experience by standardizing how apps share and leverage data. However, APIs only indirectly involve and benefit the users who subsidize this ecosystem by contributing their data. BPIs can act as a gradual path towards a more user-centric ecosystem.

Nearly a decade after the vision was first articulated, a modular web-friendly set of PETs software tools that lets developers disentangle component roles/functions in apps and workflows (thereby allowing them to minimize exposure of user data) is taking shape at @nillion.

I just love how everything is so polite and courteous, asking whats up and shaking hands and all. People should be more like dial up connections.

@CryptoMeina @juanaxyz00 Targeted advertising campaigns created in response to the online/offline activity of millions of people can already cause feedback loops that cause them to buy unhealthy food products, for example. Now this can happen even more quickly and with even more steps automated.

@andreilapets @juanaxyz00 I thought about this for a while - maybe we are all just data points for robots' ethical dilemmas? x.com/CryptoMeina/st…
Meina 🌱@CryptoMeina

Some fleshed out thoughts: I’m increasingly concerned about AI’s trajectory. It already processes information faster than our brains, and as its compute power grows, it will inevitably surpass us in total knowledge. At some point, an AI system might judge that humans consume more than we produce - so what justification would remain for our existence? Based on what we have seen so far, our unique value lies in the moral judgments we make when faced with difficult situations. Those chaotic data stabilize the system. So, maybe we are all just data points for robots' ethical dilemmas? Consider the Zeroth Law of Robotics, which states that a robot may not harm humanity—or, by inaction, allow humanity to come to harm—and that the welfare of all humanity takes precedence over any individual (or the robot’s own survival). If an AI truly internalizes this law, will it protect us, or will it decide that the best way to minimize harm is to sideline or even eliminate those it deems detrimental to humanity’s overall welfare?

One thing not explicit in this discussion is the privacy risk of a prompt for *others*: family members, friends, colleagues, and acquaintances. We may trust an individual to make informed choices about themselves based on risk feedback (though humans clearly have trouble with this), but do they trust everyone around them to do the same? Do they trust themselves to have the best interests of others in mind when evaluating such feedback?

Interesting. We had sort of discarded B2B as the sales cycles for "privacy tech" are long. But if the company is actually still getting the full functionality of openAI models, then there is not much risk for the company...just an extra layer of privacy and no trade off in productivity for their employees.

Even supposing privacy feels unimportant at the individual level, there is the question of how this impacts society collectively. We can't be sure there isn't a way to exploit aggregations of small, innocuous facts about the daily routines of millions of people. Without private spaces (to do mundane, unusual, or subversive things), society as a whole becomes a more homogenous and less diverse system, potentially too fragile to handle unforeseen disruptions (including deliberate or malicious manipulation).

tbh, I get the worries about feeding data into AI models, but the upside I’m getting still outweighs my privacy concerns. - I’m already filtering what I feed the model (detail-level, context, etc.) - I cross-check different models to see if the answers line up. - Data privacy is an endless game. Sure, you can run a TEE, store stuff locally, even train on your own server—but someone can always hack you. - The real question: what level of privacy do you actually need for the info you possess? What are the potential impact of that information? - Do you really need to encrypt what you ate today or who you argued with yesterday?

The latest release of @iabtechlab's PAIR standard addresses industry feedback and improves interoperability with digital advertising solutions like @prebidorg, showing that #privacyenhancingtechnologies like #privatesetintersection are finding adoption in real-world workflows.
IAB Tech Lab@IABTechLab

#IABTechLab is excited to release the latest version of the open PAIR 1.1 protocol! This version clarifies the definitions of several of the terms in the protocol and improves the integration with prebid with a new Open PAIR module. Read more here: okt.to/IXvS7N

It's great to see that the @FTC is examining #multipartycomputation and other #privacyenhancingtechnologies in enough detail to articulate some of the challenges associated with deploying them in production (and citing the @BU_Computing/@thebwwc wage equity effort as an example).
FTC@FTC

While an important tool to prevent intentional or accidental misuse of data, companies making representations about their use of privacy enhancing technologies must continue follow the law and ensure that any privacy representations are accurate: bit.ly/4bn3Ufq

@kayabaNerve @AvishaiY @nillion We are assembling a small interest group on the topic of non-interactive ITS MPC at correlation.org. Feel free to reach out if you think there is an overlap (or any related topics/ideas that would be exciting to discuss).

@AvishaiY @nillion I'm eager and willing to be a class group shill given my own experiment on a potentially-robust linear-complexity tECDSA signing protocol, which I'm largely review begging for, depending on them.

The claim by @nillion that has raised the most doubts, is that of an IT-secure MPC with a *non-interactive online-phase*, which apparently (as mentioned in x.com/GarbledCircus/…) contradicts a lower bound. >> That claim was recently revised >>

MPC fans might find this interesting: @nillion seems to be claiming information-theoretic MPC with *constant-round online phase* with preprocessing proportional only to circuit size (or maybe only input+output size?). 🤔

@AvishaiY @nillion To evaluate an arbitrary circuit using Nillion's technique, the circuit would need to be converted to a possibly exponentially larger multivariate polynomial ("sum of products"). While this will not always scale, it is notable that this conversion adds no rounds of communication.

After five years of work adapting secure computation to real-world scenarios, we're now at a point where web-based, consumer-facing services/products (and the ecosystems/infrastructures behind them) no longer need to put your sensitive data at risk by unnecessarily decrypting it.
