All models have some sort of translation layer between the real world and world of statistics. If you mean a common input format that obfuscates the raw input, anything that deals in a latent space could work, but they’d be pretty generic. It would be interesting if you could make a system that does statistics and (even modeling if you get it to work) with homomorphic encrypted data. That way, even the host of the model couldn’t understand what was going on
