Chong Shen Ng emphasizes the critical tension in AI development between privacy preservation and model accuracy. Among the significant threats he highlights is the attackers' ability to extract confidential information from training data patterns retained by an AI model after training.

Chong notes that, despite the perceived security of Federated AI, a degree of privacy vulnerability remains. However, stronger privacy regulations are necessary but could impede the model's performance or utility. Hence, there is growing interest in adopting Anonymous or Federated AI models to leverage domain-specific data without violating essential privacy norms.

Chong insights elaborate on:

    • How AI models can unintentionally surface patterns that expose sensitive signals from the data they were trained on.

    • Why improving privacy protections often comes at the cost of model accuracy—and how teams must navigate that trade-off deliberately.

    • Where traditional federated approaches fall short, making additional privacy-enhancing technologies essential.

    • What the growing adoption of federated AI signals about rising industry awareness around data protection.

    • Why he expects implementation timelines to shrink rapidly as federated solutions move from experimentation to mainstream deployment.

There's always a privacy utility trade-off when you train a model in a private way. If you increase the amount of privacy that you want, the utility of the model drops. Because what you do is you introduce too much noise, and your model effectively cannot learn. But if you have too little privacy or you have just a marginal amount, you might have a very good performance. There's always a trade-off there.quotation-marks icon

Here's how to navigate the privacy-security tension in AI-assisted software development:

  • Be aware of inherent threats. Understand that AI models, while not directly storing data, do retain patterns that can potentially expose underlying information.
  • Prioritize privacy-enhancing technologies. Additional measures should complement Federated AI models, given their inherent limitations in preserving user data privacy.
  • Balance utility with privacy. Acknowledge and manage the trade-off between enhancing privacy measures and maintaining model performance. Security should not compromise utility.
  • Sensitize teams about data privacy. Training sessions should inform software professionals about the importance of data privacy and secure coding practices.
  • Control access to critical AI models. Restrict access to sensitive domain-specific AI models, such as those trained using healthcare data, to authorized personnel only.
  • Adopt Federated AI progressively. Take advantage of the growth stage of Federated AI and integrate it as a new layer in your stack, enabling a more secure exploration of AI's capabilities.
  • Be patient but prepared for evolving regulation. As standards mature and compliance requirements tighten, having a privacy-first approach will pay dividends.
