SYSTEM AND METHOD FOR EASILY EXTRACTING ORIGINATION/DESTINATION FEATURES AND LISTS FOR SPAM PREVENTION FROM MESSAGES

摘要

PURPOSE: A system and a method for easily extracting origination/destination features and lists for spam prevention from messages are provided to easily identify disguised spam messages by examining a specified part of the messages. CONSTITUTION: A message receiving component(120) receives items, and extracts features related or partially related to origination of the message, and/or information to enable a receiver to contact, respond, or receive the message in association with the message. A feature extracting/deobfuscating component(130) uses a subset of the extracted features by relating to formation of a filter. A standardization component deobfuscates the features of the subset. A mechanical learning system component is used to learn spam or non-spam of the deobfuscated features.
