Detection of obscured copying using known translations files and other operational data

摘要

Systems and methods that automatically compare sets of files to determine what has been copied even when sophisticated techniques for hiding or obscuring the copying have been employed. The file compare system comprises a file compare program that uses various operational data and user interface options to detect illicit copying, highlight and align matching lines, and to produced a formatted report. A known translations file is used to match translated tokens. Other operation data files specify rules that the file program then used to improve its results. The generated report contains statistics and full disclosures of the known translations used and the other methods used in creating the exhibits. The system includes a bulk compare program that automatically detects likely file pairings and candidates for validation as known translations, which can be used on iterative runs. The user is given full control in the final output and the system automatically reforms the reports and recalculations the statistics for consistent and accurate final presentation.
