1. A method for identifying content in electronic messages, the method comprising:
- storing a plurality of thumbprints in a database in memory, wherein each of the plurality of thumbprints is associated with messages identified as spam;
receiving an electronic message sent over a communication network; and
executing instructions stored in memory, wherein execution of the instructions by a processor;
detects content in the received electronic message,identifies metadata including a numerical signature characterizing one or more colors in the content,generates a plurality of variations for the numerical signature, wherein each variation characterizes at least one aspect of content that is different from any content in the received electronic message,matches a thumbprint of at least one variation to one of the thumbprints stored in the database as being associated with spam, andclassifies the received electronic message as spam based on the match.

Abstract
Systems and methods for identifying content in electronic messages are provided. An electronic message may include certain content. The content is detected and analyzed to identify any metadata. The metadata may include a numerical signature characterizing the content. A thumbprint is generated based on the numerical signature. The thumbprint may then be compared to thumbprints of previously received messages. The comparison allows for classification of the electronic message as spam or not spam.

10. A system for identifying content in electronic messages, the system comprising:
-
memory that stores a plurality of thumbprints in a database, wherein each of the plurality of thumbprints is associated with messages identified as spam; a communication interface that receives an electronic message sent over a communication network; and a processor that executes instructions stored in memory, wherein execution of the instructions by the processor; detects content in the received electronic message, identifies metadata including a numerical signature characterizing one or more colors in the content, generates a plurality of variations for the numerical signature, wherein each variation characterizes at least one aspect of content that is different from any content in the received electronic message, matches a thumbprint of at least one variation to one of the thumbprints stored in the database as being associated with spam, and classifies the received electronic message as spam based on the match. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A non-transitory computer-readable storage medium, having embodied thereon a program executable by a processor to perform a method for identifying content in electronic messages, the method comprising:
-
storing a plurality of thumbprints in a database, wherein each of the plurality of thumbprints is associated with messages identified as spam; receiving an electronic message sent over a communication network; detecting content in the received electronic message; identifying metadata including a numerical signature characterizing one or more colors in the content; generating a plurality of variations for the numerical signature, wherein each variation characterizes at least one aspect of content that is different from any content in the received electronic message; matching a thumbprint of at least one variation to one of the thumbprints stored in the database as being associated with spam; and classifying the received electronic message as spam based on the match.
