Abstract
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 query shingles. The query fingerprint is compared to the fingerprints of the documents to be queried to determine whether there are any matches.
