Declarations under Rule 4.17: of inventorship (Rule 4.17(iv)) [Continued on next page] (54) Title: UNIQUENESS LEVEL FOR ANONYMIZED DATASETS (57) : A dataset's uniqueness level may be calculated by analyzing a dataset to determine a uniqueness level. In cases where the uniqueness level may be too low for a particular purpose, meaning when the dataset may not provide enough anonymity, the dataset may be adjusted by recomputing the dataset with different resolutions of spatial data, temporal data, content data, 102 i and relationship data. By adjusting the resolution or accuracy of the data de- 106 ments, the uniqueness level may thereby be adjusted. An error calculation may be determined by comparing the adjusted dataset to the original data, 114 and the error value may represent the consistency of the data to the original data. The uniqueness level may be used as an assurance level of anonymity, which may be advertised when a dataset is sold or transferred to a third party for analysis.
