Patterns can match sensitive information in unstructured data such as what?

The correct choice pertains to the notion of unstructured data, which includes various formats where information is not organized in a predefined manner. Word documents are prime examples of unstructured data, as they can contain a plethora of text, images, and formatting that do not adhere to a strict format, making them suitable for pattern matching to identify sensitive information.

Email addresses, credit card numbers, and social security numbers, while considered sensitive information, are typically found in structured formats. This structured data often follows a specific pattern that makes it easier to identify, such as numerical sequences or specific formats (like the pattern of social security numbers). Unlike these more structured examples, word documents can encompass complex and varied content, making them more challenging to analyze but crucial for identifying sensitive information spread throughout narrative text. This complexity highlights the relevance of utilizing patterns to sift through the vast information contained in unstructured formats like word documents.
