1. A method comprising:

determining a risk value representing a risk of re-identification for data received from a data source;

determining that the risk value does not satisfy a threshold risk value;

in response to determining that the risk value does not satisfy the threshold risk value, performing the following operations iteratively using a statistical model for a plurality of iterations, the operations comprising:

for each iteration of the plurality of iterations, updating the data with a respective transformation using the statistical model; and

determining a respective risk value representing the risk of re-identification for the updated data at the iteration; and

providing the updated data to a data pool.
