10. The method of claim 8 , wherein calculating a similarity measurement of the hash signature of the DOM object for the classification further comprises: calculating a similarity measurement between the hash signature of the DOM object and each of the plurality of the known hash signatures identified by searching the database, wherein each of the plurality of the known hash signatures are classified as confirmed for the classification or classified as dismissed for the classification; determining a predetermined number of most similar known hash signatures; weighting a similarity of the predetermined number of the most similar known hash signatures according to a distribution of similarity measurements of the predetermined number of the most similar known hash signatures; and calculating a weighted similarity of the DOM object by dividing a sum of similarity weights of a number of the most similar known hash signatures that are classified as confirmed by a sum of similarity weights of a total number of the most similar known hash signatures.
8. The method of claim 1 , wherein comparing the hash signature of the DOM object to the known hash signature of the DOM object associated with the known website further comprises: determining a classification for comparing a similarity of the website to known websites; identifying a plurality of known hash signatures, each of the plurality of known hash signatures corresponding to a different one of DOM objects, wherein each of the DOM objects corresponds to a different one of the known websites associated with the classification, and wherein the plurality of known hash signatures is identified by searching a database of hash signatures for each of the plurality of known hash signatures classified as being associated with the classification; calculating a similarity measurement of the hash signature of the DOM object for the classification; comparing the similarity measurement of the hash signature of the DOM object to a similarity threshold associated with the classification; and reporting the website as being associated with the classification based on the determining that the similarity measurement is over the similarity threshold associated with the classification.
