Abstract:
1. A method, including: receiving a first data structure having a first set of unique identifiers that identify one or more files; receiving a second data structure having a second set of unique identifiers that identify the one or more files; and verifying, using one or more processors, correspondence between the first and second data structures, including performing a mathematical function on the first and second sets of unique identifiers to produce a result indicative of correspondence, wherein the verifying includes: calculating a remainder value from a modulo operation for each identifier in the first data set and incrementing a result array using the respective remainder values; and calculating a remainder value from a modulo operation for each identifier in the second data set and decrementing the result array using the respective remainder values, where correspondence is indicated when the decrementing counters the incrementing of the result array.
