k-anonymity : is a property possessed by certain anonymized data

k-anonymity is a property possessed by certain anonymized data. The concept of k-anonymity was first introduced by Latanya Sweeney and Pierangela Samarati in a paper published in 1998[1] as an attempt to solve the problem: "Given person-specific field-structured data, produce a release of the data with scientific guarantees that the individuals who are the subjects of the data cannot be re-identified while the data remain practically useful."[2][3][4] A release of data is said to have the k-anonymity property if the information for each person contained in the release cannot be distinguished from at least {\displaystyle k-1}k – 1 individuals whose information also appear in the release.
