Abstract:
1. A method for anonymizing data over multiple temporal releases of the data, the method comprising: receiving a graph at a computer executing an anonymization engine, the graph relating to a temporal release or the multiple temporal releases of the data, the graph comprising a plurality of nodes and connections between at least two of the plurality of nodes; applying a connection prediction model to the graph to identify predicted connections between the plurality of nodes; grouping the plurality of nodes into groups of nodes; publishing an anonymized version of the graph, the anonymized version of the graph comprising the groups of nodes and a list identifying each of the plurality of nodes in each of the groups of nodes; determining if a further graph has been received, the further graph comprising additional nodes and relating to a subsequent temporal release of the data; in response to determining that the further graph has been received, placing the additional nodes included in the further graph into the groups of the nodes; and publishing a further anonymized version of the graph, the further anonymized version of the graph comprising the groups of nodes and the list.
