Systems and methods of detecting copying of code or portions of code involve disassembling a set of compiled code into an architecture-agnostic intermediate representation. The intermediate representation is used to form a number of cryptographically hashed overlapping shingles. The number of cryptographically hashed overlapping shingles can be searched against a database of cryptographically hashed overlapping shingles to identify copied code.

Detecting copied computer code using cryptographically hashed overlapping shingles

A protected querying technique involves creating shingles from a query and then fingerprinting the shingles. The documents to be queried are also shingled and then fingerprinted. The overlap between adjacent shingles for the query and the documents to be queried is different, there being less, or no overlap for the document shingles. The query fingerprint is compared to the fingerprints of the documents to be queried to determine whether there are any matches.

Protected indexing and querying of large sets of textual data

Systems and methods of detecting copying of computer code or portions of computer code involve generating unique fingerprints from compiled computer binaries. The unique fingerprints are simplified representations of functions in the compiled computer binaries and are compared with each other to identify similarities between functions in the respective compiled computer binaries. Copying can be detected when there are sufficient similarities between fingerprints of two functions.
