Coordinated de-identification of a dataset across a network

1. A method of de-identifying a dataset comprising:

receiving information from a client device at a network device, wherein the information includes a list of at least one group of techniques supported by the client device and selected from groups consisting of a group of data masking techniques and a group of data pseudonymization techniques, configuration options associated with the at least one group of techniques supported by the client device, and a first data dictionary of a dataset to be de-identified, the first data dictionary including attribute names, attribute types and associated metadata including attribute descriptions of attributes of the dataset;

mapping at the network device attributes of the first data dictionary to attributes of a second data dictionary included in the network device by matching attributes of the first data dictionary with attributes of the second data dictionary based on corresponding attribute names and attribute descriptions, the second data dictionary being different from the first data dictionary and including attribute names, attribute types and associated metadata including attribute descriptions of attributes that appear in each ingested data source, the second data dictionary further including a characterization of all direct identifiers from the each ingested data source leading to recognition of direct identifiers of the dataset;

determining at the network device first techniques and associated configuration options mutually supported by the client device and the network device based on the at least one group of techniques, wherein the determined first techniques are compatible with de-identification techniques of the network device and selected from a group of data masking techniques and data pseudonymization techniques;

sending the determined first techniques to the client device;

receiving at the network device the dataset from the client device, wherein the dataset is produced at the client device by applying one or more of the determined first techniques and the associated configuration options to corresponding attributes; and

applying a de-identification technique to the dataset at the network device to produce a resulting set of de-identified data, wherein the de-identification technique is compatible with the applied one or more first techniques and the associated configuration options to de-identify the dataset.

2. The method of claim 1 , wherein the network device resides within a cloud computing environment.

3. The method of claim 1 , wherein the attributes of the first data dictionary include one or more direct identifiers.

4. The method of claim 3 , wherein the applying the de-identification technique further comprises:

identifying one or more sets of quasi-identifiers within the dataset; and

applying the de-identification technique to the identified one or more sets of quasi-identifiers to produce the resulting set of de-identified data.

5. The method of claim 4 , wherein the identifying the one or more sets of quasi-identifiers comprises:

analyzing values of attributes of each record to find unique combinations of the values; and

identifying attributes of the unique combinations of the values as the one or more sets of quasi-identifiers.

6. The method of claim 1 , further comprising:

applying further protection to the resulting set of de-identified data at the network device to improve a privacy level by extending the one or more first techniques applied at the client device using compatible techniques supported at the network device;

identifying at least one sensitive attribute within the dataset; and

applying the de-identification technique to the at least one identified sensitive attribute to produce the resulting set of de-identified data.
