Implementation Guide

Feature 1: Apply Redaction Policy to Files Efficiently

This feature demonstrates how to apply a redaction policy across multiple files within a specified directory. Follow these steps:

Step 1: Prepare Output Directories

Create directories for storing successfully processed files and those that fail during processing.

string sourceFile = Utils.PrepareOutputDirectory("YOUR_DOCUMENT_DIRECTORY/PolicyFile.json");
var path = Path.GetDirectoryName(sourceFile);
string success_path = Path.Combine(path, "Success");
if (!Directory.Exists(success_path)) { Directory.CreateDirectory(success_path); }
string fail_path = Path.Combine(path, "Fail");
if (!Directory.Exists(fail_path)) { Directory.CreateDirectory(fail_path); }

Step 2: Load Redaction Policy

Load your redaction policy from a predefined JSON file containing rules for data to be redacted.

RedactionPolicy policy = RedactionPolicy.Load(sourceFile);

Step 3: Apply Redaction Policy to Files

Iterate through each file in your input directory, apply the redaction policy, and save the output accordingly.

foreach (var fileEntry in Directory.GetFiles("YOUR_DOCUMENT_DIRECTORY/Inbound"))
{
    using (Redactor redactor = new Redactor(fileEntry))
    {
        // Apply the redaction policy.
        RedactorChangeLog result = redactor.Apply(policy);

        // Determine where to save the output based on processing status.
        String resultFolder = result.Status != RedactionStatus.Failed ? success_path : fail_path;
        var outputFile = Path.Combine(resultFolder, Path.GetFileName(fileEntry));

        // Save the processed file.
        using (Stream fileStream = File.Create(outputFile))
        {
            redactor.Save(fileStream, new RasterizationOptions() { Enabled = false });
        }
    }
}

Feature 2: Directory Preparation for Redaction Output

This feature ensures that directories for storing output files are ready before processing begins. The above code snippet efficiently handles this step.

Practical Applications

GroupDocs.Redaction can be applied in various scenarios, such as:

  1. Legal Document Management: Automatically redact sensitive client information from legal documents.
  2. Financial Reporting: Ensure compliance by masking confidential financial data in reports.
  3. Healthcare Records Processing: Protect patient privacy by redacting identifiable information from medical records.
  4. Government Document Sharing: Safeguard citizen data when distributing public documents.
  5. Human Resources Management: Anonymize personal details in HR documents before sharing internally.

Performance Considerations

When working with large datasets or numerous files, consider these tips to optimize performance:

  • Use asynchronous file operations where possible.
  • Manage memory efficiently by disposing of streams and objects promptly.
  • Implement logging to monitor processing times and identify bottlenecks.

Following best practices for .NET memory management will ensure your application runs smoothly without excessive resource consumption.
