Deidentify a dataset
Two operations are performed on the dataset:
All ID numbers are randomized from the range 1 to n
All columns containing dates will have the year changed
The year change is done by letting the earliest year in the dataset be used as a reference and by maintaining leap years. The reference year will either be 1901, 1902, 1903 or 1904 depending on its distance to the closest preceeding leap year.
