High Code Java API to Hide & Redact Sensitive Data
Product Page | Docs | Demos | API Reference | Examples | Blog | Free Support | Temporary License
GroupDocs.Redaction for Java is on-premise API that enable your Java applications to hide and redact any sensitive or classified data, content, information, or metadata to make it completely unreadable and non-searchable.
Document Redaction Java On-premise API Features
- Preview the document by rendering it in
JPEG
,PNG
, orBMP
image format. - Text Redaction
- Replace or hide the classified text
- Search for an exact phrase and apply redaction on it.
- Support for case-sensitive & case-insensitive search.
- Support to use regular expressions (regex) search.
- Option to use a colored box as well as a replacement string for redaction.
- Metadata Redaction
- Repalce all or specific metadata values empty (blank / minimal)
- Redact the metadata values
- Apply filters to fetch the desired metadata for redaction
- Use regular expressions (regex) to filter out the desired metadata for redaction
- Ability to detect the metadata items for which the redaction failed, skipped or rejected
- Annotation Redaction
- Redact the annotation text or delete the annotations
- Remove all or specific comments from the document
- Search for specific strings within comments and then apply redaction to the matching ones
- Ability to redact specific text from within the comment instead of redacting/removing the whole comment
- Spreadsheet Redaction
- Apply redaction to specific Microsoft Excel® Worksheet or column
- Ability to apply filters to identify & designate the column to be redacted
- Image Redaction
- Redact classfied & sensitive information within an image
- Apply a colored box over the area that contains classified information
- Ability to change image metadata by acting as an
EXIF
eraser - Detect text within the image via OCR and then redact that text
- Search for a specific text to be redacted within the image using regular expressions (regex) via OCR
- Apply area redaction or text redaction on the images embedded in documents
- OCR to perform redaction on Images
- Perform OCR on scanned documents
- Perform OCR on images embedded within Microsoft Word® or PDF files
- Create PDF files with image redaction
- Support for rasterization to make redacted PDF non-searchable and without metadata
- Keeping the document formatting intact even after the removal (redaction) of sensitive data
- You may also implement custom format handler for the file formats which are not currently being supported.

Sample Java code to convert DOCX to rasterized & redacted PDF
ByteArrayInputStream inputStream = null;
// Rasterize the document before applying redactions
final Redactor raterizer = new Redactor("C:\\Temp\\sample.docx");
try
{
// Perform annotation and textual redactions, if needed
ByteArrayOutputStream stream = new ByteArrayOutputStream();
RasterizationOptions options = new RasterizationOptions();
options.setEnabled(true);
raterizer.save(stream, options);
inputStream = new ByteArrayInputStream(stream.toByteArray());
stream.close();
}
finally { raterizer.close(); }
if (inputStream != null)
{
// Re-open the rasterized PDF document to redact its pages as images
final Redactor redactor = new Redactor(inputStream);
try
{
RedactorChangeLog result = redactor.apply(new ImageAreaRedaction(new java.awt.Point(1160, 2375),
new RegionReplacementOptions(java.awt.Color.BLUE, new java.awt.Dimension(1050, 720))));
if (result.getStatus() != RedactionStatus.Failed)
{
final FileOutputStream fileStream = new FileOutputStream("C:\\Temp\\sample_docx_Raster.pdf");
try
{
RasterizationOptions options = new RasterizationOptions();
options.setEnabled(false);
redactor.save(fileStream, options);
}
finally { fileStream.close(); }
}
}
finally { redactor.close(); inputStream.close(); }
