Abstract: In some implementations, a device may provide a data structure storing first data, wherein the first data indirectly identifies second data, and wherein the second data identifies a particular individual. The device may obtain, from the data structure, the first data. The device may generate a cryptographically random value using a secure generator. The device may combine the first data and the cryptographically random value to generate hashing input data. The device may perform, using a hashing algorithm, a hashing operation on the hashing input data to generate de-identified first data, wherein re-identification of the de-identified first data requires knowledge of at least the first data, the cryptographically random value, and the de-identified first data. The device may perform an action using the de-identified first data.
