9. A system comprising: one or more hardware processors; and a memory device accessible to the one or more hardware processors, wherein the memory device stores one or more instructions that, upon execution by the one or more hardware processors, causes the one or more hardware processors to: render a document object model (DOM) object of a website using website information; generate a hash signature of the DOM object of the website by: applying a number of hashing functions to each of a plurality of data portions separated from content within the DOM object; and generating a hash signature of the DOM object of the website by selecting a number of hashed data portions of the plurality of hashed data portions; obtain a known hash signature of a DOM object associated with each of a plurality of known websites associated with a classification; compare the hash signature of the DOM object of the website to a known hash signature of the DOM object associated with each of the plurality of known websites, wherein comparing the hash signature of the DOM object of the website to the known hash signature of the DOM object associated with each of the plurality of known web sites includes comparing each of the plurality of hashed data portions to a plurality of known hashed data portions of the known hash signature; based on determining that the hash signature of the DOM object of the website does not match the known hash signature of the DOM object associated with each of the plurality of known websites: for each of the plurality of known websites associated with the classification: compute a similarity measurement between the hash signature of the DOM object of the website and the known hash signature of the DOM object associated with the known websites associated with the classification; determine whether a threshold associated with the classification is satisfied based on the similarity measurement computed between the hash signature of the DOM object of the web site and the known hash signature of the DOM object for each of the plurality of known websites; and determine whether to classify the website as confirmed for the classification based on determining whether the threshold associated with the classification is satisfied.

The system of claim 9 , wherein the website is classified as confirmed for the classification based on determining that the threshold associated with the classification is satisfied, and wherein the website is classified as dismissed for the classification based on determining that the threshold associated with the classification is not satisfied.
