Abstract

Embodiments disclosed include computer implemented systems and methods comprising multiple computer programs that when used together as part of the system enable the detection of one set of computer files within another set of files without having direct access to the files themselves. A computer program generated unique fingerprint for each set of files that is a condensed representation of that file that ensures no reverse engineering is possible from its use. Another computer program serves as a public repository to securely store fingerprints from multiple sources (e.g. companies).Additionally, another computer program is used to analyze the two or more file sets and produces a report that shows whether files in one set are contained in the other.

analyzing based on an analysis program, by the computer, the second fingerprint file with reference to the first fingerprint file to determine a presence in the second mathematical representation of any of the first elements of the first mathematical representation;

augmenting, by the computer, the second fingerprint such that the analysis program can be periodically extended over time to improve likelihood of detection of malicious tampering of files for avoiding detection by other analysis program; and

issuing, by the computer, from said analyzing, where any of the first elements of the first mathematical representation are determined to be present in the second mathematical representation, a report in relation to license authorization for using the second content engineering data to manufacture the second semiconductor device in relation to the licensed original content engineering data for manufacturing the first semiconductor device, wherein the report includes a summary of files detected and a score of a percentage of files that indicates match of files.
