10. A method for associating objects within one or more groups of objects within a plurality of objects, each object comprising a first plurality of properties, each property comprising data reflecting a characteristic of an entity represented by the object, the associated objects within a group of objects comprising matching data in corresponding properties for a second plurality of properties that includes at least some of the first plurality of properties, the method comprising the following operations performed by one or more processors: executing, for each object within the plurality of objects, the following: creating a slug for the object, the slug comprising the second plurality of properties from the object; and inputting the slug for the object into a counting Bloom filter; inputting for each created slug, the slug and its corresponding object into a multimap, if a bin within the counting Bloom filter corresponding to the slug has a count value greater than 1, wherein the slug is a key to the multimap and the object is a value to the multimap; and associating the objects stored as values for each multimap key with two or more corresponding values.

The method of claim 10 , further comprising: sizing the counting Bloom filter for a predetermined error rate and number of objects within the plurality of objects.
