Claim 8:
9. A tangible, non-transitory, machine-readable medium storing instructions that when executed by one or more processors effectuate operations comprising:
obtaining, by a computer system, a access to a machine learning model, wherein the machine learning model is a trained machine learning model, wherein the machine learning model is a foundation model, and wherein the machine learning model generates embeddings based on input records;
obtaining, by the computer system, a training data set;
determining, by the computer system, an obfuscation transform based on the machine learning model and the training data set by self-supervision, wherein determining the obfuscation transform comprises:
obtaining training embeddings based on the training set from the machine learning model;
generating the obfuscation transform based on dimensionality of the training embeddings, wherein the obfuscation transform injects noise by, for each of at least a plurality of dimensions of the training embedding, sampling from a parametric noise distribution and applying the sampled parametric noise to a given embedding;
training the obfuscation transform by adjusting parameters of the parametric noise distribution according to an objective function that is differentiable, wherein the object function comprises a measure of mutual information and a measure of data loss; and

storing, with the computer system, the trained obfuscation transform in memory.
