centralized social networks like Mastodon, combines content sharing with built-in attribution. Tim Berners-Lee's Solid protocol restructures the Web around personal data pods with granular access controls.

These technologies prioritize integrity through cryptographic verification that proves authorship, decentralized architectures that eliminate vulnerable central authorities, machine-readable semantics that make meaning explicit -- structured data formats that allow computers to understand participants and actions, such as "Alice performed surgery on Bob" -- and transparent governance where rules are visible to all. As AI systems become more autonomous, communicating directly with one another via standardized protocols, these integrity controls will be essential for maintaining trust.

Why Data Integrity Matters in AI

For AI systems, integrity is crucial in four domains. The first is decision quality. With AI increasingly contributing to decision-making in health care, justice, and finance, the integrity of both data and models' actions directly impact human welfare. Accountability is the second domain. Understanding the causes of failures requires reliable logging, audit trails, and system records.

The third domain is the security relationships between components. Many authentication systems rely on the integrity of identity information and cryptographic keys. If these elements are compromised, malicious agents could impersonate trusted systems, potentially creating cascading failures as AI agents interact and make decisions based on corrupted credentials.

Finally, integrity matters in our public definitions of safety. Governments worldwide are introducing rules for AI that focus on data accuracy, transparent algorithms, and verifiable claims about system behavior. Integrity provides the basis for meeting these legal obligations.

The importance of integrity only grows as AI systems are entrusted with more critical applications and operate with less human oversight. While people can sometimes detect integrity lapses, autonomous systems may not only miss warning signs -- they may exponentially increase the severity of breaches. Without assurances of integrity, organizations will not trust AI systems for important tasks, and we won't realize the full potential of AI.

How to Build AI Systems With Integrity

Imagine an AI system as a home we're building together. The integrity of this home doesn't rest on a single security feature but on the thoughtful integration of many elements: solid foundations, well-constructed walls, clear pathways between rooms, and shared agreements about how spaces will be used.

We begin by laying the cornerstone: cryptographic verification. Digital signatures ensure that data lineage is traceable, much like a title deed proves ownership. Decentralized identifiers act as digital passports, allowing components to prove identity independently. When the front door of our AI home recognizes visitors through their own keys rather than through a vulnerable central doorman, we create resilience in the architecture of trust.

Formal verification methods enable us to mathematically prove the structural integrity of critical components, ensuring that systems can withstand pressures placed upon them -- especially in high-stakes domains where lives may depend on an AI's decision.

Just as a well-designed home creates separate spaces, trustworthy AI systems are built with thoughtful compartmentalization. We don't rely on a single barrier but rather layer them to limit how problems in one area might affect others. Just as a kitchen fire is contained by fire doors and independent smoke alarms, training data is separated from the AI's inferences and output to limit the impact of any single failure or breach.

Throughout this AI home, we build transparency into the design: The equivalent of large windows that allow light into every corner is clear pathways from input to output. We install monitoring systems that continuously check for weaknesses, alerting us before small issues become catastrophic failures.

But a home isn't just a physical structure, it's also the agreements we make about how to live within it. Our governance frameworks act as these shared understandings. Before welcoming new residents, we provide them with certification standards. Just as landlords conduct credit checks, we conduct integrity assessments to evaluate newcomers. And we strive to be good neighbors, aligning our community agreements with broader societal expectations. Perhaps most important, we recognize that our AI home will shelter diverse individuals with varying needs. Our governance structures must reflect this diversity, bringing many stakeholders to the table. A truly trustworthy system cannot be designed only for its builders but must serve anyone authorized to eventually call it home.

That's how we'll create AI systems worthy of trust: not by blindly believing in their perfection but because we've intentionally designed them with integrity controls at every level.

A Challenge of Language

Unlike other properties of security, like "available" or "private," we don't have a common adjective form for "integrity." This makes it hard to talk about it. It turns out that there is a word in English: "integrous." The Oxford English Dictionary recorded the word used in the mid-1600s but now declares it obsolete.

We believe that the word needs to be revived. We need the ability to describe a system with integrity. We must be able to talk about integrous systems design.

The Road Ahead

Ensuring integrity in AI presents formidable challenges. As models grow larger and more complex, maintaining integrity without sacrificing performance becomes difficult. Integrity controls often require computational resources that can slow systems down -- particularly challenging for real-time applications. Another concern is that emerging technologies like quantum computing threaten current cryptographic protections. Additionally, the distributed nature of modern AI -- which relies on vast ecosystems of libraries, frameworks, and services -- presents a large attack surface.

Beyond technology, integrity depends heavily on social factors. Companies often prioritize speed to market over robust integrity controls. Development teams may lack specialized knowledge for implementing these controls, and may find it particularly difficult to integrate them into legacy systems. And while some governments have begun establishing regulations for aspects of AI, we need worldwide alignment on governance for AI integrity.

Addressing these challenges requires sustained research into verifying and enforcing integrity, as well as recovering from breaches. Priority areas include fault-tolerant algorithms for distributed learning, verifiable computation on encrypted data, techniques that maintain integrity despite adversarial attacks, and standardized metrics for certification. We also need interfaces that clearly communicate integrity status to human overseers.

As AI systems become more powerful and pervasive, the stakes for integrity have never been higher. We are enteri
