pdfSweep: what it does and why you need it
pdfSweep is an iText add-on that removes (redacts) sensitive information from a PDF (Portable Document Format) document. Confidentiality is assured, because the redacted information cannot be recovered. In a secure two-step process, pdfSweep deletes text and images at user-defined coordinates, or as defined by a regular expression. After having parsed the rendering information in the original PDF document, a new document is created without the redacted content.
