Abstract

See full text

Provided is a system and method for hybrid windowing for string-matching of input patterns to a corpus. The method including: establishing a first window size and a hash function; performing hashing on input patterns having a size within a given range using dynamic-sized windows to determine a dynamic-windowed hash set, the given range established using the first window size; performing hashing on input patterns having a size outside the given range using fixed-sized windows to determine a fixed-windowed hash set; combining the dynamic-windowed hash set and the fixed-windowed hash set to determine a combined hash set; and outputting the combined hash set for use in the confidential string-matching.
