Abstract
A data processing apparatus includes a memory configured to store a bit array including a first Bloom filter associating with a first subset containing a data element matching a first classification condition and a second Bloom filter associating with a second subset containing a data element matching a second classification condition, and a processor configured to, when a first data element to be a search target is inputted, determine whether the same data element as the first data element is present in the first subset by using the first Bloom filter, determine whether the same data element as the first data element is present in the second data subset by using the second Bloom filter, and when all the data elements contained in the first subset are deleted, delete the first Bloom filter from the bit array.
