US Patent 10484419 Classifying software modules based on fingerprinting code fragments

A method includes extracting one or more code fragments from a first software module and computing fingerprints of the code fragments extracted from the first software module. The method also includes determining a similarity score based on distances between the fingerprints of the code fragments extracted from the first software module and fingerprints of one or more code fragments extracted from at least a second software module, the second software module being classified as a given software module type, each of the fingerprints being computed by application of a fuzzy hash function to a given one of the code fragments. The method further includes classifying the first software module as the given software module type based on the similarity score and modifying access by a given client device to the first software module responsive to classifying the first software module as the given software module type.
