Automated vs Manual Blurring
In modern web browsing, private information appears in two distinct forms:
- Standard Structured Patterns: Email addresses, telephone numbers, passwords, and 16-digit credit card sequences that can be identified automatically using regex and Luhn checksum validation.
- Contextual & Unstructured Data: Proprietary client names, revenue metrics, sensitive dashboard sections, or internal database identifiers that require custom targeting.
PrivacyBlur Plus handles both scenarios through a dual detection system: Automated Background Scanners for standard identifiers and an interactive Select & Protect visual picker for custom page elements.
1. Automatic Detectors: What Gets Masked?
📧 Email Addresses
Catches standard email patterns across body text, table cells, and input fields without catching false positives.
🔑 Passwords & Tokens
Masks password fields, secret inputs, API key inputs, and authorization token fields.
📞 Phone Numbers
Identifies international E.164 and standard domestic formats across page text.
💳 Payment Cards
Mathematical Luhn Mod-10 checksum validation ensures only genuine card numbers are masked.
2. Manual "Select & Protect" Tools
For non-standard sensitive information (such as internal project codenames or whole dashboard widgets), PrivacyBlur Plus provides 4 visual picker modes:
- Select Text: Highlight any text with your mouse and click Protect selected text to generate a scoped exact-match rule.
- Select Element & Media: Hover over any table row, video card, image, or div and click to mask the target element.
- YouTube Videos & Shorts: Isolate specific YouTube videos or Shorts by permalink, masking feed thumbnails and the video player while leaving other videos unblurred.
- Select Area (Drag Box): Click and drag a bounding box over complex charts or multi-element regions to obscure all overlapping content.
- Smart Right-Click Menu: Right-click to protect elements, or right-click already-protected elements to remove protection in one click, plus 5/15/30m temporary pause.
