Abstract: Various embodiments provide processes for identification of embedded unauthorized data within document data. Such processes may include evaluating document data properties for indications of closing headers, comparing document data sizes against reference sizes, and comparing document data sizes against other document data sizes. Certain embodiments evaluating image data may evaluate image properties, such as histograms or gradient images, to determine random or otherwise unauthorized data. Upon detection of unauthorized data, the document data may be flagged for later processing, such as removal from a storage server.
