De-identifying source entity data

Abstract:

De-identification of source entity data is provided, in which a process obtains source entity data having an entity identifier and entity attribute data in respective formats for entity attributes of that entity, obtains a predefined library of fictitious entities with corresponding fictitious entity attribute data, for the entity attributes, that is in the respective formats, and generates a de-identified entity lookup list by applying a transformation to the entity identifier to produce a transformed entity identifier, selecting a fictitious entity from the predefined library of fictitious entities, and writing to the de-identified entity lookup list the entity identifier, the transformed entity identifier, and the fictitious entity attribute data, for the entity attributes, that corresponds to the selected fictitious entity. The process also processes entity file(s) using the de-identified entity lookup list to de-identify the entity and produces de-identified entity file(s).
