Outbound content filtering via automated inference detection

A computer-executed method for filtering outbound content via inference detection, the method comprising:

• receiving a piece of outbound content;
• extracting keywords from the outbound content;
• issuing Web queries based on the keywords;
• extracting keywords from documents corresponding to the hits returned by a search engine in response to the queries;
• ranking the keywords extracted from the hits;
• selecting one or more raniked keywords to represent the outbound content;
• and
• producing a result which indicates a destination identifier for the outbound content and at least one keyword which is selected to represent the outbound content, thereby allowing a user to determine whether the outbound content has the proper content and destination identifier.

A computer system for filtering outbound content via inference detection, the computer system comprising:

• a processor;
• a memory coupled to the processor;
• an content-selection mechanism configured to identify previously sent content with a common first destination identifier;
• a keyword-extraction mechanism configured to extract a set of keywords from the identified previously sent content;
• a query mechanism configured to:
• issue a number of Web search queries based on the keywords extracted from the identified content;
• receive a number of hits in response to the queries;
• extract a set of expected-content keywords from the hits;
• and
• associate the expected-content keywords with the first destination identifier;
• a receiving mechanism configured to receive a piece of outbound content;
• a decision mechanism configured to determine the number of expected-content keywords present in the outbound content;
• and
• a display mechanism configured to produce a result which indicates the destination identifier for the outbound content and at least one expected-content keyword present in the outbound content, thereby allowing a user to determine whether the outbound content has the proper content and destination identifier.

• a processor;
• a memory coupled to the processor;
• a receiving mechanism configured to receive a piece of outbound content;
• a first keyword-extraction mechanism configured to extract keywords from the output content;
• a query formulation mechanism configured to issue Web queries based on the keywords;
• a second keyword-extraction mechanism configured to extract keywords from documents corresponding to the hits returned by a search engine in response to the queries;
• a ranking mechanism configured to rank the keywords extracted from the hits;
• a selection mechanism configured to select one or more ranked keywords to represent the outbound content;
• and
• a display mechanism configured to produce a result which indicates a destination identifier for the outbound content and at least one keyword which is selected to represent the outbound content, thereby allowing a user to determine whether the outbound content has the proper content and destination identifier.
