11. The system of claim 5 , wherein the identifying the at least one data element with information entropy at least equal to a threshold information entropy further comprises: determining a baseline information entropy that indicates a randomness of information included in a set of documents that includes the document; analyzing the document to determine an information entropy of at least one portion of the document; determining that the information entropy of the at least one portion of the document is equal to at least the threshold information entropy, the threshold information entropy based at least in part on the baseline information entropy; and identifying the at least one portion of the document as the at least one data element.
