Implementation Guide

Metadata Redaction Feature

Overview The metadata redaction feature allows you to remove all embedded metadata from a document, ensuring no sensitive information is leaked.

Step 1: Load the Document Using Redactor

// Initialize the Redactor object with the path to your document.
Redactor redactor = new Redactor("YOUR_DOCUMENT_DIRECTORY/sample.docx");

Why?: Loading the document initializes the process and prepares it for metadata removal.

Step 2: Apply Metadata Redaction

// Remove all metadata using EraseMetadataRedaction with MetadataFilters.All.
redactor.apply(new EraseMetadataRedaction(MetadataFilters.All));

Why?: This step ensures that every piece of metadata is stripped from the document, enhancing privacy.

Step 3: Configure SaveOptions

// Set options for saving the redacted document.
SaveOptions saveOptions = new SaveOptions();
saveOptions.setAddSuffix(true); // Appends a suffix to the output filename.
saveOptions.setRasterizeToPDF(false); // Maintains the original format.

Why?: Configuring these options ensures that your document is saved correctly without altering its format.

Step 4: Save the Redacted Document

// Save the document with the configured options.
redactor.save(saveOptions);

Why?: This final step writes the changes to a new file, preserving the original document.

Troubleshooting Tips

  • Common Issue: File not found errors. Ensure the path is correct and accessible.
  • Solution: Double-check your directory structure and permissions.

Practical Applications

Metadata redaction has numerous real-world applications:

  1. Legal Documents: Protect client confidentiality by removing metadata before sharing drafts.
  2. Financial Reports: Ensure sensitive company information isn’t exposed through metadata.
