Abstract
Methods and systems for identifying content of interest. Accessed textual information is processed by at least one of character unification, phrase unification, and concept unification. A configured processor executes at least one predefined rule to determine whether the unified content includes certain types of information. Unified content that matches may be subject to further action such as alerts, encryption, logging, etc.
Claims20
A method for identifying content of interest, the method comprising:
- accessing, through an interface to a programmable device, a text for analysis;
- applying, using a configured processor, at least one unification process to the accessed text to create a processed text, the at least one unification process selected from the group consisting of character unification, phrase unification, and concept unification;
- comparing, using the configured processor, the processed text to at least one predefined rule to identify content of interest;
- and
- issuing, using the configured processor, an alert indicating that content of interest has been identified in the processed text.
A system for identifying content of interest, the system comprising:
- an interface to a programmable device configured to access a text for analysis;
- a processor in communication with the interface, the processor configured to:
- apply at least one unification process to the accessed text to create a processed text, the at least one unification process selected from the group consisting of character unification, phrase unification, and concept unification;
- compare the processed text to at least one predefined rule to identify content of interest;
- and
- issue an alert indicating that content of interest has been identified in the processed text;
- and
- a data store in communication with the processor, the data store containing the at least one predefined rule.
A computer readable medium containing computer-executable instructions for performing a method for identifying content of interest, the medium comprising:
- computer-executable instructions for accessing, through an interface to a programmable device, a text for analysis;
- computer-executable instructions for applying, using a configured processor, at least one unification process to the accessed text to create a processed text, the at least one unification process selected from the group consisting of character unification, phrase unification, and concept unification;
- computer-executable instructions for comparing, using the configured processor, the processed text to at least one predefined rule to identify content of interest, the at least one predefined rule including at least one of a token and a regular expression;
- computer-executable instructions for issuing, using the configured processor, an alert indicating that content of interest has been identified in the processed text;
- and
- computer-executable instructions for preventing the transmission of the accessed text beyond the programmable device.
