Document matching engine using asymmetric signature generation
First Claim
1. An automated method of document matching using asymmetrical signature generation, the method comprising:
- receiving documents from a document repository;
generating signatures for each of the documents using a first signature generator;
providing the signatures and a document identifier for each of the documents to a signature database;
receiving an input document;
generating signatures for the input document using a second signature generator; and
searching the signature database using the signatures generated for the input document,wherein the first and second signature generators are configured such that different numbers of signatures are generated for a same document.

Abstract
An automated method of matching an input document to a set of documents from a document repository. A signature database is stored, the signature database including a document identifier and signatures generated by a first signature generator for each of the set of documents. The input document is received and signatures are generated for the input document using a second signature generator, and the signature database is searched using the signatures generated for the input document. The first and second signature generators are configured such that different numbers of signatures are generated for a same document. Other embodiments, aspects and features are also disclosed.
