Intel's Tiber AI: Confidential Federated Learning Redefined with Confidential Computing

Introduction

As AI is reinventing industries, data security and privacy continue to be the most important challenges so far. Intel's Tiber Secure Federated AI service proposes addressing this by having a secure means of training AI without needing to move sensitive data.

Rather than filling AI models with data, Tiber reverses that—seeding fragments of AI models via a secure pipeline to communicate with data where it lives. That's especially critical in healthcare and finance, where data security needs to be paramount above all else.

How Tiber Secure Federated AI Works

Traditionally, AI models need huge amounts of data, which are being moved across networks, and there are threats of data exposure and compliance violations. Intel's Tiber service uses confidential computing, so data never leaves its source. This is how it works:

This federated learning process allows organizations to work together on AI training without exchanging sensitive data.

Key Use Cases: A Game Changer for Regulated Industries

Intel's Tiber AI is well suited to companies requiring the best security and AI training offloaded to regulatory compliance requirements, i.e.:

"Businesses can take advantage of next-gen AI breakthroughs while assisting in delivering data confidentiality and AI model trustworthiness of data for multi-party collaboration in distributed environments," says Rajan Panchanathan, Head of Product, Intel's Trust and Security Services.

The Role of Confidential Computing

Underpinned by Tiber's security architecture is Intel's Trusted Execution Environment (TDX), which provides an even more secure safe for processing data. Confidential computing does protect interactions of sensitive data with the model from access except by authorized systems and staff.

Security issues still exist, though, as prior breaches of confidential computing architecture foretell weaknesses that need to be continuously enhanced.

Challenges in Federated AI Training

While federated AI training offers significant advantages, it also comes with its own set of challenges:

• Data Standardization and Quality: Standardization and quality of data within companies are the pillars of AI model performance.
• Governance and Collaboration: Multi-party AI building requires precise agreements on objectives, security controls, and regulatory requirements.
• Security Vulnerabilities: Previous security weaknesses in secure computing environments, such as attacks against TDX and AMD's SEV-SNP, highlight the ongoing need for improvement.

Binary CEO Alex Matrosov comments, "It's very challenging to truly have confidential computing when companies just layer on top of a broken-by-design stack. We need to go back and rebuild the building blocks first before we get to make that kind of flashy claim."

Conclusion

Intel's Tiber Secure Federated AI is an important milestone in securing AI training by using confidential computing to protect data while enabling federated AI co-development.

While there are obstacles, the fact that it provides a secure, federated learning platform makes it a viable option for industries handling sensitive data. As AI security continues to evolve, technologies like Tiber will play a key role in fostering a world where businesses can harness AI's potential without compromising data privacy.
