1. A system for obscuring private information in input data, the system comprising:
a computing device comprising at least one processor and an associated storage device, the at least one processor programmed to perform operations comprising:
accessing an input data unit;
applying an encoder model to the input data unit to generate a latent space representation of the input data unit in a latent space, the latent space having a first latent space dimension and a second latent space dimension;
applying multi-dimensional noise to the latent space representation of the input data unit, the multi-dimensional noise having a first value in the first latent space dimension and a second value different than the first value in the second latent space dimension; and
applying a decoder model to the latent space representation of the input data unit to generate an obscured data unit.
