Abstract
Various implementations disclosed herein provide a method for anonymizing data in a distributed hierarchical network. In various implementations, the method includes determining a first set of attribute hierarchy counts that indicate a number of occurrences of corresponding attributes that are stored at the first network node and have not been transmitted upstream towards the hub. In various implementations, the method includes receiving, from a second network node, a second set of attribute hierarchy counts that indicate a number of occurrences of corresponding attributes at the second network node. In various implementations, the method includes determining whether a sum based on the first and second set of attribute hierarchy counts satisfies an anonymization criterion. In some implementations, the sum indicates a total number of occurrences for a corresponding attribute that are stored at the first and second network nodes and have not been transmitted upstream towards the hub.
