Abstract

Systems and methods for detecting copies of documents are described. In one example, a system and method for detecting copies of documents utilizes multiple authentication tests performed using original and scanned copy detection patterns. The system captures a CDP that may be skewed or improperly sized. The system also retrieves or reconstitutes the expected CDP. Then the system performs a first correlation to determine if the captured CDP indicates the correct document identification and then if necessary, one or more authentication tests are applied wherein the authentication test may be grouped into distinct orthogonal test groups. The authentication tests applied may be selected according to usefulness, system throughput or target document valuation parameters.
