clasificando el enmascaramiento de datos correctamente [cerrado]

Is data masking a synonym for anonymisation, or or is one of several methods to anonymise data? I read alot about it but now i got a bit confused. Maybe it's because people use it as a synonym, or it really is.

Data Masking isn't a synonym for Data Anonymisation.

Data Anonymisation is making data such that it can't be uniquely mapped to a given entity.

It is quite difficult because even after most Data Anonymisation techniques have been applied to a given data set, if relationships between certain elements in the data remain, these can be used in conjunction with other non anonymised data sets to associate data with a given entity even when the original data set has no direct means for entity association.

Data Masking is a technique used to attempt Data Anonymisation, specifically an attempt of the Data Perturbation type.

Other techniques used in Data Anonymisation include

  • Data Aggregation (Making new summary data from old data that results in loss of entity association precision both directly and via data relationships
  • Data Reduction (Removing data from the data set, either on a record basis or variable basis or by re-coding that variable or variable combination to ensure loss of entity association precision both directly and via data relationships)
  • Data Perturbation (Modifying the data in the data set)
  • Synthetic microdata (Generation of an entire new data set based on the some of the statisical properties of the old data set but with completely synthetic data)
