1. A method to determine an authenticity of an Integrated Circuit (IC) by computer comprising the steps of:

  • providing a computer configured to perform a pattern matching process and an authentication process, and an imager communicatively coupled to said computer, said imager configured to image a package or a die of at least one IC;

    providing a reference library accessible by said computer;

    imaging a die of at least one IC and a package of said at least one IC to generate an image of a package and an image of a die of said at least one IC;

    selecting by computer at least one library image from said reference library which corresponds to said at least one IC based on a first manufacturer mark within said image of a package or within said image of a die;

    performing at least the following comparing steps of a mark in any order;

    comparing by computer by pattern matching said mark found in said image of a package or said image of a die to said mark in said library image and generating a first indicator of a quality of a first pattern match;

    comparing by computer by pattern matching said mark or another mark found in said image of a package to said mark or another mark in said image of said die and generating a second indicator of the quality of a second pattern match; and

    determining by computer an indication of confidence of authenticity of said at least one IC based on said first indicator and said second indicator and accepting said at least one IC as authentic if said indication of confidence of authenticity is greater than an authenticity threshold.
