Abstract
Systems, methods, computer program products, and means are provided for verifying the integrity of data structures. A system includes a first data structure, a second data structure, and a fingerprint block. The first data structure has a first set of unique identifiers. The second data structure has a second set of unique identifiers. The fingerprint block verifies correspondence between the first and second data structures by performing a mathematical function on the first and second sets of unique identifiers to produce a result indicative of correspondence.
