Degree-Based Network Anonymization
منشور في 2020"…Our model suggests a convenient privacy level for each net- work based on the standard deviation of its degrees. The objective is to modify the degrees in a way that respects some given local restrictions, per node, such that the total modifications at the global level (in the whole graph/network) are bounded by some given value. …"
