摘要： A method for detecting possible fraud in a document includes receiving an electronic image of the document and extracting data from the image that includes a plurality of printed characters. Next, one or more properties of the characters are measured, the properties are compared to at least one corresponding normative property to determine whether anomalies are present, and a determination is made as to whether to provide a fraud alert based on the anomalies, if any. Preferably, the method includes reporting the one or more anomalies, if any, to a classifier engine, wherein the classifier engine determines whether to provide the alert. Also, methods for determining character spacing ands/or acuity are provided.

摘要： A method of printing a two-dimensional barcode by tilting the print head, which results in tilted barcode, and methods of detecting various types of attempts to forge the tilted barcode including: (i) a low level forgery that consists of a simple scan and reprint of the barcode, (ii) a low level forgery that consists of a reproduction (i.e., a read and regeneration) and subsequent printing of the barcode using a printer with a non-tilted print head by a fraudster that is not aware of the tilt in the original barcode, and (iii) a higher level forgery by a fraudster that is aware of the tilt in the original barcode and that digitally tilts/shears an image of the barcode and prints the digitally tilted/sheared image using a printer with a non-tilted print head in an effort to mimic the tilt present in the legitimate barcode.

摘要： A confidentiality preserving system and method for performing a rank-ordered search and retrieval of contents of a data collection. The system includes at least one computer system including a search and retrieval algorithm using term frequency and/or similar features for rank-ordering selective contents of the data collection, and enabling secure retrieval of the selective contents based on the rank-order. The search and retrieval algorithm includes a baseline algorithm, a partially server oriented algorithm, and/or a fully server oriented algorithm. The partially and/or fully server oriented algorithms use homomorphic and/or order preserving encryption for enabling search capability from a user other than an owner of the contents of the data collection. The confidentiality preserving method includes using term frequency for rank-ordering selective contents of the data collection, and retrieving the selective contents based on the rank-order.
