Claim 14:
15. A system, comprising:
a database storing a biometric dataset of biometric datums;
a user interface that receives a value k representing a number of records to hide a biometric datum among, a value t that represents a t-closeness parameter for a t-close distribution, a weight parameter, a first number of features to retain for determining an attribute of interest, and the attribute of interest; and
an electronic device comprising a computer processor and a memory storing an anonymization computer program that receives the value k, the value t, the value w, the value n1, and the attribute of interest, calculates a distribution of the attribute of interest in the biometric dataset, splits the biometric dataset into a plurality of k-sized clusters that satisfy the t-close distribution, anonymizes each biometric datum in the plurality of k-sized clusters using a weighted average of landmarks for the biometric datums in k-sized clusters using the weight parameter, adds each anonymized biometric datum into an anonymized biometric dataset, and persists the anonymized biometric dataset.
