I can help you create an application that identifies and masks personally identifiable information (PII) in photos and documents. This is a common need for privacy protection when sharing documents.

Let's build a Next.js application that:

1. Accepts image uploads
2. Uses AI to detect potential PII
3. Masks the sensitive information
4. Provides the redacted image for safe sharing

How It Works

1. Upload Interface: Users can upload photos or documents containing potential PII
2. Processing: The application processes the image to identify sensitive information
3. Masking: Black redaction boxes are placed over detected PII
4. Download: Users can download the masked version for safe sharing

Implementation Notes

• In a production application, you would integrate with AI services like AWS Rekognition, Google Cloud Vision, or Azure Computer Vision to accurately detect PII
• The demo uses simulated masking for illustration purposes

• For a complete solution, you would need to implement:

  • More sophisticated PII detection algorithms
  • Different masking techniques (blurring, pixelation, etc.)
  • Support for multiple document types
  • Secure handling of the original documents

Would you like me to expand on any specific part of this implementation?

I'll fix that error. The issue is with how we're creating the image element in the processImage function. Let's correct it:

The error occurred because new HTMLImageElement() is not the correct way to create an image element in JavaScript. Instead, we should use document.createElement('img') which is the standard DOM API for creating HTML elements.

This change will fix the error and allow the image processing to work correctly. The rest of the code remains the same and should function as expected.
