Markov anonymization process to increase data set anonymity. Markov processes to increase the anonymity level in a data set: an increase in the anonymity level of a data set, for example, increasing from k = 50 to k = 100, could be achieved by increasing the skew level of the k = 50 data set without knowledge of the authentic data. If increases are done in this way, the risk of a reverse identification attempt using averaging can be avoided.
