Systems and methods are disclosed for the utilization of personally identifiable information (PII) to identify an individual while de-identifying the associated data through tokenization. A method includes receiving, at a main tokenizer and from a first trading partner, a first data set comprising a first subset of a plurality of PII fields corresponding to an individual, receiving, at the main tokenizer and from a second trading partner, a second data set comprising a second subset of the plurality of PII fields corresponding to the individual, resolving, a the main tokenizer, the individual, linking a unique patient-centric token (PCT) to the individual based on the resolving, and outputting the PCT for generating a non-PII token linked to the individual.

Referential data grouping and tokenization for longitudinal use of de-identified data

Certain implementations of the disclosed technology include systems and methods for external linking based on hierarchal level weightings. The method may include associating external query data having one or more query field values with a record in a linked hierarchical database. The linked hierarchical database may include a plurality of records, each record having a record identifier and representing an entity in a hierarchy, each record associated with a hierarchy level, each record including one or more fields, each field configured to contain a field value. The associating may include receiving the external query data, wherein the external query data includes one or more search values; and identifying, from the plurality of records in the linked hierarchical database, one or more matched fields having field values that at least partially match the one or more search values.
