Abstract
A method of identifying potential phishing abuse images includes: producing a first color map that represents a subset of color values and pixel locations within a base image; producing a second color map that represents color values and pixel locations within a target image; selecting an alignment the first color map with the second color map such that at least some pixel locations of the first color map align with at least some pixel locations of the second color map; determining a measure of color value matching of aligned pixel locations for the selected alignment; and repeating the acts of selecting and determining until a prescribed threshold measure of color value matching is determined for at least one of the selected alignments or until an evaluation limit is reached.
Claims20
A method of identifying potential phishing abuse images, comprising:
- generating a plurality of base color palettes, each representing a subset of color values within a different base image of a plurality of base images;
- generating a target color palette that represents a subset of color values within a target image;
- for each base color palette of the plurality of base color palettes:
- comparing the target color palette with said each base color palette to generate a score,
- associating the score with the base image that corresponds to said each base color palette, and
- determining whether the score exceeds a threshold;
- comparing the target image with a base image only if the score associated with the base image exceeds the threshold;
- wherein the method is performed by one or more computing devices.
