Abstract
Monitored content is classified to determine partial matches with fragments of documents. A set of redundant keys, or sliding sectional fingerprints, are computed for every possible alignment of the documents with respect to the monitored content. The keys are stored in repositories according to the classification of the corresponding documents. Sectional fingerprints are computed for the monitored content, and the repositories are searched. If a match is found in a repository corresponding to public content, then the monitored data section is classified as public. If a match is found only in a repository corresponding to private content, then the data section is classified as private. Otherwise, the data section is classified as unknown. In a related aspect, a set of policies are searched for a first match in part according to the classifications of the monitored data sections, and a designated action taken if the first match is found.
