Arbitrary Reduction of Validation Error for AI Decision Tests using Homomorphic AI and Repetition Codes

arXiv:2606.28994v1 Announce Type: cross Abstract: This paper presents new results and breakthrough obtained with the HbHAI techniques (Hash-based Homomorphic Artificial Intelligence) proposed in \cite{filiol0,sepp}. HbHAI is based on a novel class of key-dependent hash functions that naturally preserve most similarity properties, most AI algorithms rely on. It enables to analyse and process data in its cryptographically secure form while using existing native AI algorithms without modification, with unprecedented performances compared to existing homomorphic encryption schemes and most notably

Why this matters
Why now

The increasing need for privacy-preserving AI and secure data processing is driving innovation in homomorphic AI techniques, with new breakthroughs like HbHAI emerging.

Why it’s important

This development proposes a method to process sensitive data with AI without decryption, potentially addressing critical cybersecurity and privacy concerns while maintaining AI performance.

What changes

The ability to run existing AI algorithms on cryptographically secure data 'as is' could significantly accelerate the adoption of privacy-preserving AI across various industries.

Winners
  • · AI algorithm developers
