## Redactions
269
+
The instructor can specify the redaction of portions of one or more
270
+
pages of each student's PDF that contain their name or other
271
+
personally identifying information. The original unredacted PDF is
272
+
saved on the server, but Submitty also prepares .png images of each
273
+
page of the PDF with the specified areas redacted (covered with a grey
274
+
checkerboard pattern). When the grader is in blinded or anonymous
275
+
mode, the redacted .png file will be displayed.

When you upload a bulk PDF, you may want to redact certain information from the students' submissions. Submitty allows you to prepare redactions for the bulk PDF uploads. These redactions will be shown to limited access graders, and along with blinded grading, will help maintain student privacy.

### Preparing Redactions
262
-
To prepare for redactions, you must first create a redactions JSON file. This file should contain the pages and coordinates of the areas you want to redact. The format of the JSON file is as follows where coordinates are in the range of 0 to 1, representing a percentage of the page dimensions:
278
+
To enable page redactions, enter the "Edit Gradeable" menu, make sure
279
+
you have enabled "Manual Grading", then click on the "Rubric" panel,
280
+
and click "yes" for "Are student submissions/uploads a single file PDF
Here is a sample of the JSON format for the page redactions. This
287
+
sample places a rectangle on the first and second pages of the
288
+
document. The (x,y) coordinates specify the upper left and lower
289
+
right corners of each rectangle, where (0,0) is the upper left and
290
+
(1,1) is the lower right corner.

In order to be able to turn on redactions for the gradeable, you must turn on "Are student submissions/uploads a single file PDF with a fixed/prescribed format?" in the "Rubric" tab. This will allow you to upload new redactions json files.
Once you have prepared the redactions JSON file, either start a bulk upload or view an existing bulk upload submission. You will see boxes on the PDF that represent the redactions you have prepared. These boxes will be shown to limited access graders, and they will not be able to see the content within these redacted areas.
