Abstract:
1. A method, comprising; scanning, by a programmable control device, a data element for a known unwanted data and placing an entry corresponding to the data element in a table external to the data element, said table including a plurality of entries, at least one entry corresponding to each data element scanned for the known unwanted data, each entry including information identifying the data element and a version of the known unwanted data used in the scan of the data element, wherein scanning and placing the entry does not modify the data element; receiving, at the programmable control device, a request to scan the data element; retrieving, by the programmable control device, in response to receiving said request, the entry from the table identifying the version of the known unwanted data used when the data element was previously scanned, wherein the entry is retrieved from the plurality of entries in the table utilizing a document identifier of the data element, wherein said retrieving the entry is performed without accessing the data element; determining, by the programmable control device, in response to receiving said request, if a current version of the known unwanted data is equal to the version of the known unwanted data used when the data element was previously scanned; and omitting, by the programmable control device, scanning of the data element in response to a determination of equal versions of the known unwanted data.
