Properties

visual_type

Type
String
Required
true

A machine-readable identifier that indicates the type of file tampering visualization offered in this image. This value will not change; you may rely on it in your application logic.

Possible Values

  • tamper_overview: Tampered fields are highlighted in red.
  • edit_regions: Red highlights indicate the areas of the original document that were changed.
  • original_pdf: Red highlights indicate the areas of the original document that were changed.
  • tampered_fonts: The same field appears to use multiple fonts. Where possible, the fonts within a field are highlighted with different colors.
  • added_fonts: Text that was added to the document is highlighted in red.
  • overwritten_text: Text has been added to (or modified from) the original document. Where possible, unchanged text will be highlighted in green while added text will be highlighted in red. In some cases, only one of these two regions will be shown; this still indicates suspicious activity.
  • misaligned_text: Fields do not match the expected alignment based on where they appear in the doc and how other similar fields in the document are aligned.
  • post_whiteout_content: Indicates that the document is redacted using a photo editor and shows the redacted field values that have been recovered.
