Abstract

The invention discloses a system and method for censoring documents of release-sensitive information. The system preferably uses a censor database of restricted or sensitive terms to filter a document for occurrences of the restricted terms. When such restricted terms are found in the document, they are highlighted or marked to preferably draw the user'"'"'s attention. A second database of alternate non-restricted terms, which correspond to the restricted terms, is preferably used to offer non-restricted terms to replace the restricted ones. Both databases are preferably customizable by users, and may also preferably include access restrictions in order to ensure the accuracy of the censor terms as well as the alternative non-restricted terms.

Claims

1. A computerized document censor comprising:

a censor database of restricted terms;

a text comparator program for finding ones of said restricted terms in said document; and

a text highlighter program for highlighting said restricted terms found in said document.

2. The document censor of claim 1 further comprising:

a generalization database of non-restricted terms, wherein ones of said non-restricted terms correspond to ones of said restricted terms.

3. The document censor of claim 1 wherein said restricted terms comprise at least one of:

single words;

phrases; and

numbers.

4. The document censor of claim 1 wherein said text comparator program finds ones of said restricted terms via rules-based relationships.

5. The document censor of claim 1 wherein said non-restricted terms are gathered into said generalization database by a user.

6. The document censor of claim 2 wherein said censor provides alternative ones of said non-restricted terms to a user for selectively replacing said restricted terms found in said document.

7. The document censor of claim 2 further comprising:

a text editor for replacing said restricted terms found in said documents with selected ones of said non-restricted terms.

8. The document censor of claim 2 wherein said censor database and said generalization database are accessible by remote users.

9. A method for censoring a document comprising the steps of:

storing a list of prohibited expressions;

filtering said document to find ones of said prohibited expressions; and

visibly marking ones of said prohibited expressions found in said document.

10. The method of claim 9 further comprising the steps of:

storing a list of alternate expressions corresponding to said prohibited expressions;

and presenting a group of said alternative expressions corresponding to ones of said prohibited expressions found in said document.

11. The method of claim 9 wherein said storing said list of said prohibited expressions step comprises at least one of the steps of:

entering prohibited words;

entering prohibited phrases; and

entering rules of prohibited communication relationships.

12. The method of claim 10 wherein said storing said list of said alternate expressions step comprises at least one of the steps of:

entering alternate words;

entering alternate phrases; and

entering rules of alternate communication relationships.

13. The method of claim 10 further comprising the steps of:

selecting a corresponding alternate expression from said presented group of said alternate expressions; and

replacing said prohibited expression found in said document with said selected corresponding alternate expression.

14. The method of claim 9 wherein said storing said list of prohibited expressions is restricted to at least one predetermined administrator.

15. The method of claim 10 wherein said storing said list of alternate expressions is restricted to at least one predetermined administrator.

17. The computer program product of claim 16 further comprising:

means for storing a list of generalized expressions corresponding to said restricted expressions; and

means for presenting a group of said generalized expressions corresponding to ones of said restricted expressions found in said document.

18. The computer program product of claim 16 wherein said means for storing said list of said restricted expressions comprises at least one of:

means for entering restricted words;

means for entering restricted phrases; and

means for entering rules of restricted communication relationships.

19. The computer program product of claim 17 wherein said means for storing said list of said generalized expressions comprises at least one of:

means for entering generalized words;

means for entering generalized phrases; and

means for entering rules of generalized communication relationships.

20. The computer program product of claim 17 further comprising:

means for selecting a corresponding generalized expression from said presented group of said generalized expressions; and

means for replacing said restricted expression found in said document with said selected corresponding generalized expression.

16. A computer program product having a computer readable medium having computer program logic recorded thereon for reviewing a document for restricted expressions comprising:

means for storing a list of said restricted expressions;

means for searching said document to find ones of said restricted expressions; and

means for visibly marking ones of said restricted expressions found in said document.
