Table 24 – Public-Key security handler user access permissions

Bit position

Meaning

2

When set permits change of encryption and enables all other permissions.

3

Print the document (possibly not at the highest quality level, depending on whether bit 12 is also set).

4

Modify the contents of the document by operations other than those controlled by bits 6, 9, and 11.

5

Copy or otherwise extract text and graphics from the document by operations other than that controlled by bit 10.

6

Add or modify text annotations, fill in interactive form fields, and, if bit 4 is also set, create or modify interactive form fields (including signature fields).

9

Fill in existing interactive form fields (including signature fields), even if bit 6 is clear.

10

Extract text and graphics (in support of accessibility to users with disabilities or for other purposes).

11

Assemble the document (insert, rotate, or delete pages and create bookmarks or thumbnail images), even if bit 4 is clear.

12

Print the document to a representation from which a faithful digital copy of the PDF content could be generated. When this bit is clear (and bit 3 is set), printing is limited to a low-level representation of the appearance, possibly of degraded quality.
