A submission anonymization plugin for OJS

anonymizer

A plugin that removes identifying properties from uploaded submissions in OJS

About

This plugin for OJS removes identifying properties from submission uploads based on file type. Note that it does not remove identifying data from the contents of a submission, but only from its file metadata. The user is expected to anonymize the contents.

Requirements

OJS 3.0

Installation

Copy the plugin contents to plugins/generic folder.

Configuration

1. Enable the plugin from Settings -> Website -> Plugins

2. Install the command line tool you'd like to use to remove metadata from a document.

In the OJS config.inc.php, under the section [anon], add the command line invocation for the desired file type, where file type can be default, excel, html, image, pdf, word, epub or zip.

For example, for a PDF, we can use exiftool and qpdf to remove metadata. We'd assign the following command:

[anon]
anon[pdf] = "exiftool -all:all= '$fileName' && qpdf --linearize '$fileName' '$fileName_temp' && mv '$fileName_temp' '$fileName' && rm '$fileName_original'"

$fileName will automatically substitute the uploaded file into the command line invocation.
