# About Restricting Operations

## Restricting the display of documents

You can restrict a document from being opened or displayed as a thumbnail in Desk.
For the password-protected security, you set a password for opening a document and allow only the users who know that password to open the document.
For the Electronic Signature-protected security, you specify an Electronic Signature for opening a document and allow only the users who have that Electronic Signature to open the document.
For the Digital Certificate-protected security, you specify a certificate for opening a document and allow only the users who have the private key for that certificate to open the document. Certificates registered with [Personal] in the Windows Certificate Manager are considered to have a private key.

## Restricting the operations of documents

The operations that can be restricted are the same regardless of the security module used. You can set 4 types of operation restrictions for each document or binder. Use these restrictions when you don't want your documents or binders modified or re-used.

### When operations on documents are prohibited

Operations such as moving, adding, or deleting pages, stacking or unstacking, rotating, reducing noise, changing the organization of documents in a binder, and adding or deleting original data are not possible. Annotations can be manipulated.

### When operations on annotations are prohibited

Operations such as hiding or showing, adding, editing, and deleting annotations are not possible.
Copying or editing OLE annotations can also be prohibited.

### When printing is prohibited

Printing and print previewing are not possible. Also internal processing used for printing (such as [Page Layout] plug-in, [Conversion to PDF(DocuWorks PDF)] plug-in or [Conversion to PDF(Adobe PDF)] plug-in) cannot be used.
Since printing on DocuWorks Printer or on paper can be prohibited, there is no risk that documents are copied when converted back to electronic data.

### When copying is prohibited

Operations such as copying a page, an annotation, or a document in a binder, exporting original data, and image conversion are not possible.
Information such as attributes (thumbnail view, document outline, custom attributes, page properties, settings for each annotation, etc.) and operations such as copying while editing OLE annotations can be copied even when copying is prohibited.
Since copying a page to another document can be prohibited, there is no risk that the page is printed or edited after being copied.
Note

- Combine the prohibitions above to attain the intended restriction effect.
- See "Restricted Operations for Protected Documents (Desk / Viewer)" for more information on how each setting affects operations.
- Screen capture or file manipulation cannot be restricted. If you want to restrict them, we recommend that you use software that controls system function.
- You can specify whether to show prohibited operations when a protected document is opened, by using [DocuWorks Viewer Options] in the [Preferences] dialog box.

## Full access mode

In full access mode, restricted operations can be performed on the document regardless of the security settings. You can also change or remove the security settings.
For the password-protected security, you set a full access password and allow only the users who know that password to open the document in full access mode.
For Electronic Signature-protected security, you specify an Electronic Signature that grants full access mode to users and allow only the users who have that Electronic Signature to open the document in full access mode.
For Digital Certificate-protected security, you specify a certificate that grants full access mode to users and allow only the users who have the private key for that certificate to open the document in full access mode. Certificates listed on the [Personal] in the Windows Certificate Manager are considered to have a private key.
