Patent ID: 8893281

Claim:
A computer implemented method for predicting and outputting an impact of a security breach at a particular computer in an enterprise comprising: a. electronically accessing data files available at a plurality of computers in the enterprise; b. reading the contents of the data files and identifying data files having a threshold similarity as different versions of a document, thereby determining a plurality of documents, wherein each said document is a collection of similar data files; c. accessing data indicating group assignments of computers in said plurality of computers, the group assignments indicating rank, department, business function, user, or other criteria of the computers, d. calculating a document security value of each said document based upon the document's distribution with respect to said computers and groups; e. predicting the impact of a security breach to said particular computer by combining document security values of documents present on said particular computer; wherein the impact (I c ) for a computer (c) is determined by I c =Σ c V d , where the summation Σ combines security values (V d ) for documents present on computer (c); ands f. outputting the predicted impact.
