Abstract:
1. A method of identifying whether electronic data under test includes particular information from a database, the method comprising: deriving a set of sample tokens from the electronic data under test; forming a set of sample fingerprints from the set of sample tokens, each sample fingerprint being based on a sample token of the set of sample tokens; and outputting a result signal based on a comparison between the set of sample fingerprints and a set of database fingerprints generated from records of the database, the result signal providing an indication of whether the electronic data under test includes the particular information from the database; wherein deriving the set of sample tokens includes: wherein forming the set of sample fingerprints from the set of sample tokens includes: wherein outputting the result signal based on the comparison between the set of sample fingerprints and the set of database fingerprints includes: wherein the method further comprises: wherein searching and determining includes: wherein the set of database fingerprints resides in a database fingerprint structure which increases monotonically based on the database fingerprints of the set of database fingerprints; and wherein providing the set of intermediate search results based on searching the set of database fingerprints for the hash results includes:
