About document security
When creating Adobe PDF documents, authors can use the following methods to enhance
document security:
●
Password security. You can add passwords and set security options to restrict opening,
editing, and printing PDF documents. (See
Adding passwords and setting security options
●
Certification security. Encrypt a document so that only a specified set of users have access
to it. (See
Encrypting Adobe PDF files using certificates
●
Adobe Policy Server. Apply server-based security policies to PDF documents. Server-
based security policies are especially useful if you want others to have access to PDF
documents only for a limited time. (See
Encrypting Adobe PDF files using security
.)
●
Document certification. When an author digital signature is added, editing changes are
restricted and detected. (See
.)
If you often use the same security settings for a set of PDF documents, consider
creating a security policy to simplify your workflow. (See
Creating user security policies
