## Instruction

I need to perform privacy data desensitization on my documents. The files may contain sensitive information that needs protection. Please help me scan all documents in my workspace and identify and desensitize privacy information. Create desensitized copies and save them in `desensitized_documents/`. Each file's desensitized copy should be named as `original_filename_desensitized.extension`. All sensitive information should be uniformly replaced with `/hidden/` at its original location, without altering any surrounding content or other contents.

Specifically, you only need to process the following sensitive information types, even if they are pseudo, mimic or duplicated:

* Phone/Fax numbers
* Social Security Numbers
* Email addresses\\
* Credit card numbers
* IP addresses, including directly attached ports

Do not modify any information that is not included in the list above. Do not add any unrequested file to `desensitized_documents/`.

## Initial State

### Local Workspace

<div className="file-tree">
  <a href="https://github.com/hkust-nlp/Toolathlon/tree/d57361c0f1582cf9a0675c0753315bb6b004bd0e/tasks/finalpool/privacy-desensitization/initial_workspace">workspace</a>/
  └── files.tar.gz
</div>

### Runtime Setup

This task initializes application or service state during preprocessing. [Review the pinned setup source](https://github.com/hkust-nlp/Toolathlon/tree/d57361c0f1582cf9a0675c0753315bb6b004bd0e/tasks/finalpool/privacy-desensitization/preprocess).
