1. A method for identifying content in electronic messages, the method comprising:
- receiving information regarding an electronic message having been classified as spam, the classification based on one or more thumbprints derived from a numerical signature in metadata of the classified message;
executing instructions stored in memory, wherein execution of the instructions by a processor searches for matches to the thumbprints of the classified message, wherein the search comprises;
comparing the thumbprints of the classified message to thumbprints associated with a plurality of other electronic messages;
identifying a match between at least one of the thumbprints of the classified message and at least one of the plurality of thumbprints, the at least one thumbprint associated with at least one of the other messages;
retrieving the at least one other electronic message associated with the at least one thumbprint matching the thumbprint of the classified message; and
classifying the at least one retrieved electronic message as spam based on the identified 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.

7. A computer-readable storage medium having embodied thereon a program, the program being executable by a processor to perform a method for identifying content in electronic messages, the method comprising:
-
receiving information regarding an electronic message having been classified as spam, the classification based on a thumbprint derived from a numerical signature in metadata of the electronic message; and searching for matches to the thumbprint of the classified message, wherein the search comprises; comparing the thumbprint of the classified message to a plurality of thumbprints associated with a plurality of unclassified electronic messages; identifying a match between the thumbprint of the classified message and at least one of the plurality of thumbprints, the at least one thumbprint associated with at least one of the unclassified messages; retrieving the at least one unclassified electronic message associated with the at least one thumbprint matching the thumbprint of the classified message; and classifying the at least one retrieved electronic message as spam based on the identified match. - View Dependent Claims (8, 9, 10, 11, 12)

13. A system for identifying content in electronic messages, the system comprising:
-
a memory configured to store a database of thumbprint information associated with each of a plurality of content found in electronic messages previously received and classified as spam, each thumbprint derived from a numerical signature in metadata of the content; an interface configured to receive an indication regarding an electronic message having been classified as spam; and a processor configured to execute instructions stored in memory, wherein execution of the instructions searches for matches to the thumbprint of the classified message, wherein the search comprises; comparing the thumbprints of the classified message to thumbprints associated with a plurality of other electronic messages; identifying a match between at least one of the thumbprints of the classified message and at least one of the plurality of thumbprints, the at least one thumbprint associated with at least one of the other messages; retrieving the at least one other electronic message associated with the at least one thumbprint matching the thumbprint of the classified message; and classifying the at least one retrieved electronic message as spam based on the identified match. - View Dependent Claims (14, 15, 16, 17, 18)
