Abstract

The invention provides a method and device for resisting the image junk e-mail. The method and device comprises a feature vector extractor, a junk image identifier, a screenshot functional module and an e-mail platform, especially the feature vector for extracting the image of the junk e-mail via the image carried by the image junk e-mail. The method archives the feature information of the feature vector in the text format, and transfers the image match into the match of the feature information text comprising the feature vector, which significantly enhances the efficiency of the image match, and saves the system expense. The technical solution of the invention integrally provides a technical line different form the prior anti-junk e-mail line for solving the confirmation and the filter for the image junk e-mail, and the invention improves the speed and the precision of the technical solution for the image junk e-mail, and enhances the capacity for identifying the avoiding interference for the junk image by the junk makers.
