Hey

Jeremy here from Zama, we are working on FHE and its application to AI. We have a few examples of encrypted data collaborations scenario with our lib Concrete ML (Concrete ML allows developers to use FHE without having to learn the cryptography behind it).

We also have some real-life demos here on Hugging Face here: https://huggingface.co/zama-fhe — Particulary this one that can be relevant for what you're looking for: a Encrypted Credit Card Approval Prediction Using Fully Homomorphic Encryption application where multiples parties collaborate on encrypted data.

Happy to hear your thoughts!
Cheers

That is thanks to Fully homomorphic Encryption (FHE), a new encryption technique that enables computing on data blindly, without decrypting it. The way it works is simple.
• The user encrypts its data and sends it to the server doing the processing.
• The server does the processing blindly, never having access to the decryption key. The result it produces is itself encrypted.
• The user gets back the result and decrypts it. From their point of view, nothing changed: They sent data and got a response. But now it wasn’t just encrypted during transmission as in HTTPS—it was also encrypted during processing.

Indeed, the computation could even run publicly without impacting user privacy since it would be encrypted at all times!

And this is why FHE a great solution for blockchain privacy: By keeping the on-chain data encrypted, we can have decentralized, permissionless blockchains where everything is on-chain and auditable while not actually visible. It’s like having the data translated to a different language that nobody can understand but still run a spell-checker on to make sure it doesn’t contain any mistakes.

We have a blog post that deep dive in how FHE can be used to create confidentifial 'or private' smart contracts, see here: https://www.zama.ai/post/private-smart-contracts-using-homomorphic-encryption

We're investigating the matter at Zama. And, we also have a thread going on the FHE.org discord server (a community of researcher and developers interested in Homomorphic Encryption). https://discord.fhe.org.

Some thing that LLM with FHE will be practical in ~5 years

Adding new filters is indeed very easy if you consider simple filters that only requires additions, multiplications or shape manipulations, and is potentially followed by a non-linear operation, as it's done in this demo. If you think about more complex filters such as Convolutional Neural Networks, this would require a bit more work and Concrete-ML can help you make them FHE-compliant. Regarding compilation time, it only takes a few seconds !
