Abstract
Surrogate hashing is described, including a database configured to store data associated with a first file and a second file, and a processor configured to run a first hashing algorithm against a first portion of a first file to generate a first hash value, and running a second hashing algorithm against the first portion of the first file to generate a second hash value, to determine whether the first hash value and the second hash value are substantially similar to one or more stored hash values associated with a second portion of a second file, wherein the second portion is identified by one or more attributes that are substantially similar to one or more corresponding attributes associated with the first portion, and to identify a location of the second file if the first hash value and the second hash value are substantially similar to the one or more stored hash values associated with the second portion of the second file.
