Project Description

The project focuses on training AI models on data encrypted through Fully Homomorphic Encryption (FHE), a cutting-edge approach aimed at safeguarding user privacy while enabling secure data processing. FHE is a form of encryption that allows computations to be performed directly on encrypted data without needing to decrypt it first. This means that AI models can process data, perform predictions, or extract insights without ever exposing the raw, sensitive information. By leveraging FHE, the project seeks to address critical privacy concerns associated with the increasing use of AI in sensitive domains like healthcare, finance, and personal data analytics.

Traditional methods of encrypting data require decryption before processing, which exposes the data to potential breaches and compromises privacy. However, FHE allows data to remain encrypted throughout the entire AI training and inference process. This approach ensures that user data remains confidential, as it is never revealed to the model, the infrastructure, or even the developers managing the AI system. This level of privacy protection is particularly crucial in today’s landscape, where data privacy regulations like GDPR and CCPA demand stringent measures to protect personal information.

The challenge of integrating FHE with AI training lies in the computational overhead and complexity of working with encrypted data. Encrypted data is often significantly larger and more complex to manipulate than plaintext data, making the training process computationally intensive and slower. However, advancements in both FHE schemes and AI model optimization are gradually mitigating these hurdles, making the combination more feasible.

This project aims to push the boundaries of AI and cryptography, developing systems where privacy does not come at the expense of performance or accuracy. By enabling AI models to operate on encrypted data, it envisions a future where user privacy is not just an afterthought but a foundational aspect of AI-driven solutions.
