Abstract
A system that determines whether a data element exists within a set of data elements observed from a stream of data. During operation, the system receives a query which seeks to determine whether the data element exists within a set of data elements observed from a stream of data. In response to the query, the system performs a lookup in an enhanced Bloom filter to determine whether the pattern of data elements was observed in the stream of data, wherein the enhanced Bloom filter includes multiple instances of a Bloom filter, and wherein each instance of the Bloom filter is associated with a different time interval. If so, the system generates a notification that the data element was observed.
